오랜만에 채널 들어왔는데 영상 퀄리티랑 프로젝트 퀄리티가 완전 업그레이드 되었네요. 잘 보고 갑니다. 언제 한 번 뵙고 싶네요!

The SIM7600G-H is EOL. The SIM7600G-H R2 is the recommended modual to use. It costs ~$50 usd.

[@ThatProject]

Thank you for good information.

[@Gerald-iz7mv]

@hwhack do you have a link to the SIM7600-H R2?

[@Gerald-iz7mv]

@hwhack It seems The SIM7600G-H R2 only comes in this big package with this battery already - is there one without that battery - where did you order it?

[@birhon]

​@@Gerald-iz7mv also looking for one without battery, let me know if you find anything

[@stevegulick7656]

The slow sped is consistent with the baud rate form the ESp32 to the modem- 115200 bits per second = 11520 bytes per second - so 120kB file at 11.5kB per sec would take 10.41 sec plus some overhead. Try a faster UART baud rate.

[@ThatProject]

Thank you for your comments. When I was working on this project, I tested by changing the baud rate between LTE modems, but there was no change in transfer speed. Maybe I'm missing something else?

[@SA-oj3bo]

Did you check if you used LTE and what LTE-mode the module was in? UMTS R99 speed: 384 kbps DL/UL HSPA+: 5.76 Mbps(UL), 42 Mbps(DL) HSDPA/HSUPA: 2.2 Mbps(UL), 2.8 Mbps(DL) LTE CAT 1: 10 Mbps(DL) 5 Mbps(UL) LTE-FDD CAT4 ：150 Mbps (DL)，50 Mbps (UL) LTE-TDD CAT4 ：130 Mbps (DL)，35 Mbps (UL)@@ThatProject Did you use baudrate up to max? Baud rate: 300bps to 4Mbps

This is an absolutely amazing project, but this board is soo expensive. 😢

[@birhon]

Sooo cool thank you! I am a noob, did you make this board from scratch?

[@ThatProject]

Thank you. I used products from LilyGo for this project.

[@rajmehta9706]

Could you kindly explain how to update the firmware of an ESP32 using an LTE Modem, specifically the SIM7600G-H model? I'm interested in the process, including any required hardware setup, software configuration, and steps to ensure a reliable update. Additionally, if there are any particular best practices or precautions to consider, I'd appreciate your insights. Thank you!

[@ThatProject]

I'll give it a try when I get a good chance. Thank you.

Hi is a similar approach to upload images on server using sim800/900 series possible over 2G network? As I get iot enabled 2G SIM cards for dirt cheap prices!

[@ThatProject]

I don't know if you can use the same way to update images over a 2G network but it's worth trying.

can we use esp32 cam board with sim800l module if yes we need tutorial sir love from india

[@EasyOne]

[@sahasourav8157]

Sim7600 has USB 2.0 (USB device mode only). Do you think it is possible to interface the module with MCU via USB & achieve high data rate ?

[@ThatProject]

If you control directly using AT mode, it seems that you can use it like a modem. Have a look at this www.waveshare.com/wiki/SIM7600E-H_4G_HAT

[@Gerald-iz7mv]

Can you also make a video about the T-SIM7600 R2 and a solar cell and a camera (e.g. OSV5640, OV2640) with live streaming?

[@ThatProject]

Maybe. Let me think about that project.

[@chaihow-to6300]

Can you make the device call you back and listen to the microphone on the device ?

[@ThatProject]

It's a very interesting idea. In order for that to be possible, a continuous phone connection must be established, but that part may not be easy.

[@timvandusen4192]

What phone did you select in order to order the sim card? It seems a phone needs to be selected - no option to enter simcom as what the sim card is for.

[@ThatProject]

Since I chose a data-only SIM card, I did not choose which phone to use.

[@timvandusen4192]

unfortunately now there is not option to choose a data only plan without first selecting a phone of some sort. Do you by chance have a new link that would get me to the data-only plan without selecting a phone? The link you provided for the referral code just goes to a main landing page.

[@ThatProject]

@@timvandusen4192 In my case, I think I was able to apply for a data-only SIM because I was already using Google Fi. Would you please check this out? I'm not sure.

[@timvandusen4192]

I found out that all nano-SIM cards are the same, so I just found a phone that takes the nano-SIM and selected that as the one. Anxious to see how it works. BTW, awesome video! Very much appreciate you taking the time and effort to be so thorough.

[@Gerald-iz7mv]

Is there any way to modify your code to have the t-simcam board go into deep hibernation and only wake every 60 minutes to take a photo, send it over LTE to a server, then go back to deep hibernation?

[@ThatProject]

Yes, it seems possible enough. After taking and uploading a picture, you can switch to Deep Sleep mode using the following function. void deep_sleep(int seconds) { esp_sleep_enable_timer_wakeup(seconds * uS_TO_S_FACTOR); // uS_TO_S_FACTOR 1000000ULL // Conversion factor for micro seconds to seconds esp_deep_sleep_start(); }

[@smartassist9700]

What is Google server using as OS? Linux? Or does it matter? (I prefer self server to store my data.

[@ThatProject]

Usually, cloud servers run on Linux. You can choose any OS according to your options.

[@smartassist9700]

What about personal server (raspberry pi 4). Then how do I access from cell phone? (That way I do not think I need gsm from Google. Right?

[@ThatProject]

If you have a personal server in your local server, you can access it from your phone via WiFi. The purpose of this project is to demonstrate updating to a cloud server using GSM within an MCU environment.

[@fun-giri]

since weeks I tried to make it run, but everything I do I only get this error: if (!client.connect(server, port)) { Serial.println("... failed"); } What can I do? GPRS Connection is established

[@ThatProject]

If so, your server is not ready to accept to connect to any connections. How did you set up your server?

[@fun-giri]

@@ThatProjectthank you for the answer. I check the firewall rules (of my google cloud VM) and I didn't create a firewall rules. Instead I created a firewall policy. Now it works fantastic. Sorry for my comment. Maybe someone else has the same error :)

[@kienvictor736]

What do you think about video or voice streaming with this set up. Is it even possible with 12s of delay ?:))

[@ThatProject]

This is not possible with my current settings. Please let me have more drill down for the LTE connection. This is my first cellular project so I need to do more to use 100%.
