At last the dual band on expressif 👍 I wish they did not abandonned to Ethernet PHY and would have brought a 10Mb/s MAC as well... This would make a great WCH alternative and a MCU multiknife 🎉 Meanwhile we have to choose between wifi and ethernet on RISC V 🥴

[@AndreasSpiess]

Having ethernet and WiFi in the same project is probably not a typical scenario. At least here, I usually decide which connection I need and then decide on the chip. The SW interfaces are very similar.

[@testman9541]

@AndreasSpiess Well having both means you can design either redundant ethernet or use the radio for non wifi scenarii for bridge/edge deployment and keep the core full Ethernet+IP. Plus it means you use only one chip/design for all your customer deploymen choices. Here for building IoT if it is WiFi people might choose Espressif for good reasons, but if WiFi is not acceptable for usual security reason then you will have to move to WCH or others ... Or plan to have a board design that accept boths. This adds costs to the bottom line. I would have thought they would have brought a 10base T1S compatible chip, the first MCU with a PHY/MAC on board for it. Definitivelly a killer for automotive or building IoT if they keep the same price point... Thanks for your great videos 👍

[@bigdantn]

@@testman9541 what's the problem with using W5500 or similar SPI Ethernet chips together with C5?

[@callumkingunderwood]

@@testman9541 The standard ESP32 is still actively supported, and the P4 also has RMII. ESP-IDF does now have support for 1 RMII phy for 10Base-T1S also.

[@testman9541]

@callumkingunderwood Nice that T1S is there in idf tnx 👍but unlike WCH there have no phy bundled which means increasing the BOM 🥴 which also means that for T1S you still have to bring a pricey T1S phy 😭 Look like the ESP32 original is most becoming a "legacy" as none outside P4 of the other offspring have brought any wired ethernet ... And none have PHY. Odd.

[@a_pullin]

Amazing. I've always wondered why so few radios included a 5Ghz radio. Sort of assumed it was some process or FET/silicon technology limitation. Now if they just made a 100 pin package version, we could use it for literally everything.

[@AndreasSpiess]

Then it probably would be too expensive for most applications not needing such a big case...

[@a_pullin]

@@AndreasSpiess Would it? I always wonder about this. Adding more GPIO logic and pad drivers would be only a small amount of silicon, I would image. But maybe adding just the area to bond out 30+ more GPIO's might take a tone of area and make it totally uneconomical. Same for the actual packaging, too. But I don't know the economics of it. Still - a high-gpio ESP32-* would be pretty useful.

[@svideodotorg]

If both radios can run at once, this would conceivably allow one to light up a BT to WiFi gateway/proxy device (similar to ESPhome BT proxies) but with much better performance. The 5.8GHz radio can stay in touch with the network while 2.4 is open to receive BT traffic.

[@AndreasSpiess]

I would be astonished if both radios would run at the same time. But maybe they found a way to keep connections on both bands in parallel.

[@desmond-hawkins]

This is very cool and a long time coming, as you pointed out! But I don't understand the mention of "5.8" GHz, is it specific to a particular region? 802.11a was defined all the way back in 1999, and most bands are closer to 5GHz than 5.8GHz. What's so specific about 5.8GHz here? In the original bands (U-NII-1, U-NII-2/2e, U-NII-3) only channel 161 is over 5.8GHz. This makes me wonder if if will support the common bands used indoors (5.15-5.25) or if this chip is actually limited to some very specific channels. Channel 161 at 5.805 GHz is usually more recommended for long-range outdoors use, which isn't particularly where I use my Espressif chips to be honest. Even in newer standards 5.8GHz still only means channels 149-161 so this feels weirdly limited.

[@AndreasSpiess]

You are right about the frequencies. They only differ a bit between regions. I could have used 5GHz, but many people confuse it with 5G cellular technology. In Amateur Radio, our Band is called 5.8GHz. This is why I used it here. But after your comment, I changed the title to 5GHz.

[@mikemalone9678]

The biggest problem with the ESP32 is the lack of good quality analogue peripherals like ADCs, DACs and OpAmps, not the lack of wireless capabilities.

[@AndreasSpiess]

I assume this depends on the application. Not many of my projects use an ADC for anything other than measuring battery voltage.

[@mikemalone9678]

@@AndreasSpiess I use multiple ADCs in practically all of mine. Monitoring and/or controlling a solar panel or wind gen system, monitoring and/or controlling charge systems or inverter systems as examples. Monitoring home energy use. The STM32 series have a wonderful array of analogue peripherals, but lack WiFi. The ESP has very nice WiFi, but horrible analogue. It's a real pity to have to cobble two devices together when one should really do.

I got two sample devkits (with metal case) 3 weeks ago and have been playing with them since. My projects involves 8 channel audio 24/44 over UDP - which works nicely in the 5 GHz band with 11ax 😁 I measured an iperf throughput of about 62 MBit/s with a UDP payload of 1440 bytes and an average UDP packet latency of 540 +/- 180 μs (yeah, jitter).

[@TheEmbeddedHobbyist]

5.8GHz is fine if you want highspeed over a shorter range, but if the ESP32 can't or does not need the highspeed data rates then 2.4GHz will be just fine. Which is why if you want lower power or greater distances you drop back to lower frequency's or much slower data rates and hence narrower bandwidths.

[@AndreasSpiess]

I agree. In addition, it depends on the environment. If you live in a congested area, maybe 5.8GHz is also needed.

[@TheEmbeddedHobbyist]

@@AndreasSpiess In my mum's house the 2.4GHz only just about gets out of the room. i would not expect 5.8GHz to get out of the room at all. we had to put a wifi over mains extender to get a good signal in the kitchen which has only one wall between it and the router. One good thing is it's very electrically quiet and your mobile don't ring much. 🙂

[@rdyer8764]

I watched Great Scott's video earlier today concerning ESP32 and Zigbee. Since I'm not familiar with Zigbee yet, I may be wrong about this, but I thought he found the current draw to be minuscule. Was he just measuring the RF draw of an existing commercial device (he had a few), or did I misinterpret his testing?

[@AndreasSpiess]

You are right. Zigbee devices usually consume very little power. That is the reason for my critic

Thank you for evaluating the 5.8 GHz ESP32. Sad, that it is so power hungry. What I am really missing in my home automation is a low power (e.g. zigbee) epaper display unit running on batteries. BTW: I converted all my aqara motion sensors to AA. They are running for years and I have not to touch (and adjust) the sensors when replacing the batteries.

[@AndreasSpiess]

Interesting idea! I only have a handful of PIR sensors. So I prefer the small form factor and easy mount.

[@zyeborm]

These things are typically power hungry because they aren't going to sleep. You probably won't do it on a dev board but deep sleep on a c6 is meant to be 10uA which is a little high (smaller mcus get down around 3) but should still last a year on some AAA cells. Then it wakes up, pulls the power for a few milliseconds and goes back to sleep. The difference with wifi and ZigBee is the setup time, wifi is often seconds, ZigBee doesn't have one, just wake up and blast your packet then go back to sleep. There is very little that you can do if you want to Rx signals in something like real time that remains low power. There are some wifi modes that come close but that's more solar power will keep it alive then pure battery for months.

[@klassichd10]

@@AndreasSpiess My PIRs are hidden on furnitures or similar objects. So, I can also hide the batteries on or in these furnitures. Some of them are placed quite deep and upside down. I have them in every room and I trigger all the Ikea zigbee ceiling light panels with them - via ioBroker.

@@zyeborm Thank you, I started home automation in 2011 using the Homematic system. Those units are using 868MHz and draw little current during sleeping or listening. During communication they are using 20mA up to 30mA for one or two seconds. They also have a very good battery life.

[@mcplanet2495]

Do the ESP32-C5 and C6, with their HP and LP cores, support SMP in FreeRTOS by utilizing the LP core as a second real processor? If not, does multitasking still improve overall performance or speed? This would be particularly useful for a use case where a sensor is being read while the data is simultaneously transmitted via wireless communication in real time, with minimal delay (e.g., millisecond-level).

[@AndreasSpiess]

I never looked at the LP core on these chips. Only at the LP core of the ESP32. There, it had very limited functionality and had to be programmed in assembler. So most probably no SMP

[@siteking4289]

What is that naming scheme from espressif? Why is the C5 newer than the C6? Quite a Deutsche Bahn ICE3 Neo move..

[@originalmianos]

I would not be holding my breath for Arduino support for this for a long time. The Arduino support is on version esp-idf 5.1 and the Espressif is on 5.3. The support for the C5 would likely come in 5.4. Unless they back port the C5 support to 5.1. It does not affect me much as I am only using esp chips these days so I spent the time to use the idf, and once you get used to it, other than the annoying changes to the drivers in the 5.3, it's amazingly stable and very easy to use

[@johannobermeier4730]

Well, the early working Arduino version for the C5 is already done. The problem is more to get the hardware ;-)

[@originalmianos]

@johannobermeier4730 where is this? I just looked the c5 is not even supported in 5.4 beta, they said it won't be in until 5.5. I was not aware the esp32 Arduino supports anything beyond 5.1.

[@AndreasSpiess]

We should shortly get a "preview". Whatever this will be. We also have to wait for the chips...

Range and power consumption are usually pretty important factors I would say. A chip with worse performance in both areas seems very niche. Probably a decent choice if you need high bandwidth (either audio, photo or video), in which case you are going to be connected to mains anyways so the consumption doesn't matter.

[@AndreasSpiess]

I agree with power and range. We will see how important the 5.8GHz feature will become, also as a marketing argument.

AINT NO WAY

Maybe somebody figured out that 2,4 g wifi sucks ass in the real world

[@AndreasSpiess]

So far I have no big problems. But I live in a non-congested area.

[@moormoor4281]

Is this the product

[@karlbesser1696]

Das Dumme ist nur, dass man diese Elektronik nicht mehr einfach in Elektronikläden kaufen kann und bestellen muss.

[@AndreasSpiess]

Gibt es bei euch noch Elektronikläden? Da habt ihr Glück!

[@karlbesser1696]

@AndreasSpiess Hallo Andreas, leider hat Conrad vor ein paar Jahren seine Filiale in Graz aufgelöst. Geblieben sind nur kleine Läden mit bescheidenem Sortiment.

[@EpicLPer]

I'm always so immensely confused with all the names... cause why is the C5 newer than the C6 with more features? 🥲🥲🥲

[@AndreasSpiess]

Maybe because of the 5GHz?

[@zeffster2]

maybe they planned to be finished with the C5 sooner, but the C6-team were better and suprised everyone

[@patrikdavid8597]

Please please please turn off that KZbin autodubbing nonsense. It destroys your USP, the Swiss accent, and makes your videos unwatchable

[@imbalos]

How does an optional feature make his videos unwatchable?

[@patrikdavid8597]

@imbalos cause its not optional on 3rd party yt clients

[@imbalos]

@@patrikdavid8597 sound kinda selfish.

[@AndreasSpiess]

You have to switch to English. KZbin added this Feature for everybody not using English Language clients

[@patrikdavid8597]

@@imbalos just out of curiosity, do you watch the video dubbed or did you ever listen to it? Its just terrible sounding and it will never be able to translate the emotions a human voice has. If you don't speak English, watch a few videos with subs and you will learn verry quick. Thats a win win, unlike robotic dubbing which is loose loose. But yeah, you are right, I am selfish cause I like hear the Swiss accent of the guy with the Swiss accent
