This video will guide you with how you can make your own ESPNOW to Blynk Gateway and I have also explained how data Is being transferred from ESPNOW to Blynk cloud.

Awesome, this is a combined project of json, blynk and ESPNOW 👍🏻👍🏻

[@buddhimaamarasinghe9997]

Make more videos about ESP NOW. I learned a lot from your videos . Thanks

[@techiesms]

Already lined up 😉 Stay tuned…

[@basictv1947]

You can use only one esp32 for espnow and sending data to cloud. There is no need of two esp32 for communication

[@Maertaugh]

I m agree with that. Why use 2 esp32 ?

[@marcarleto79]

There is some restrictions while using wifi and esp now: esp now must keep the same wifi channel and the router change it automatically but unfortunately esp now not. I'd like to use both for my projects, specially thinking OTA firmware updates. Do you have some solution or demo project to workaround this issues?

[@venkateshgovindaiah5826]

@@Maertaugh When using only one esp32 module to switch between esp_now and wifi (lan) it will stop receiving data from other esp-now end devices (sensors modules). Imagine this scenario when there are many esp_now devices. Also every wifi routers (even the ones we use at home) are constantly switching channels. This is for security reasons and in response all wifi devices switch to the changed channel to match the router so they can continue to maintain active connections. To be connected to the wifi your ESP_NOW gateway device should be switching the channel appropriately to maintain active wifi connection with your home router. But EPS_NOW mandates that all esp-now (peers) devices/modules should be configured to use the same static channel. Well, if your router switched to a diff channel and yoru esp_now g/w did not, then there is no connection. This is why 2 esp32 modules are used here. 1 to act as a receiver/coordinator for all esp-now peer devices and the 2nd acts as a wifi gateway module to your home wifi network and the two modules are communicating over the RX2 and TX2 pins using UART. Hope this helps.

Great job bro best way of explanation and fully open no hidden work thanks bro

why use two on gateway cant we use only one esp for espnow and oled and blynk cloud

[@khookengsuen1428]

Hello @techiesms. I have two questions. 1. Can you use one ESP instead of two (ESP1 and ESP2) for the central connection between espnow and Blynk? So I don't have to use uart communication. Or will it interfere the ESP connection between espnow and Blynk cloud? 2. Is it possible that the data from ESP3 broadcast to ESP2 via ESP4 (assuming ESP4 does not use the data from ESP3)? I have a project with distance concern, so I'm afraid maybe ESP3 is too far away to send the data to ESP2. Not sure if ESP3 can send to ESP4 then to ESP2.

[@dhruvloshali2621]

I have question 1 too. Why did we need a dedicated ESP1?

[@raymondmichael4987]

For question 1; It's doable, using one esp board to handle both espnow and blynk; but it's some what complex; because espnow need the channel to be fixed, like channel 4, but WiFi which access blynk is prone to changing fore instance when using one hotspot to another, that will cause not reliable espnow communication. But having one board handle espnow communication will allow it's channel to be fixed while allowing the other to be free roaming. for question 2; I think you better look for mesh network like topology,

[@NiteshKumar-fg9qo]

can use other servers other than blynk server in your projects, you always use blynk servers.

[@JamesWattMusic]

can you explain why 2 esp32 is needed in the gateway. Why cant esp32 receive the esp-now, and send to wifi all on 1 board?

[@tareshgupta1095]

why do we need two esp32 on controller side? esp32 once connected with a blynkserver cannot utilize espnow and vicaversa?

[@babuyokesh1196]

i have only two esp 32 can i use two for blynk gateway and use esp 8266 instead of other two esp32 conmected to sensor and relay

[@marcodaddeo118]

Hello, but where can I find the wiring diagram of the board and then send it to pcb. Thank you very much and congratulations for the idea

[@nagarava]

You are using only espe32, why not mix with esp8266 and why not use memory card with espe32?

[@smilekarthik]

Great buddy, next level moving ahead

Cant we simultanosly connect one ESP32 to Internet network and broadcast to other ESPs the data received from the internet ?

Nice solution. Thank you!

Awesome & Great works! By the way where can i buy the PCB?

[@KartihkCg80]

Is it possible to make the same project on esp8266?

[@pasinduelectronic1955]

We can use esp8266 bord ?

[@marcarleto79]

Thanks bro, I have some questions: 1) I know the wifi channel restriction to use wifi and esp now simultaneously, so that's the reason you're using two esp32 instead one for gateway, right? Do you know a solution to workaround this channel thing and then use only one esp32 as a gateway? 2) even using two esp32 as gateway and assuming this is a commercial solution, how to update the firmware for the other 3 esp32 (2, 3 and 4)? It is possible to use OTA for them? 3) Do you have something similar to this video but using esp rainmaker instead of blynk?

[@charantejah3181]

Hi sir Can we transfer audio and video from one esp32 to another esp 32 through esp now protocol

[@marinehm]

Can this be accomplished without Blynk cloud? Raspberry Pi perhaps on the local network?

[@TheSleepyCraftsman]

How about a version without Blynk?

[@krishnaghatol1391]

Can you please make an explainer video on what are and how to use Virtual Pins?

[@aaronalquiza9680]

virtual pins are just channels that constantly update data. they're just observables in the cloud. you can use i think up to 10 virtual pins (paired with a data stream) per template in Blynk cloud, assigning a data type, min-max values, etc. your devices will subscribe to the virtual pin/channel (BLYNK_WRITE), and whenever data changes in the channel, the devices react via their handlers. and your devices can also write values to that channel (Blynk.virtualWrite()) and will update that virtual pin's value and rebroadcast the change.

How to upload Esp 32 bin file to Esp8266??

[@gnar-ninja]

hello sir, are you available for consultations? i have an esp based project i'd like to run by you

[@santoshgurral66]

Why can't we connect all the esp directly to blynk? Why is the gateway esp needed?

[@khookengsuen1428]

Blynk has a limit for how many devices are connected to it. Also, the amount of data received by Blynk is another limitation.

[@deepakyadav-kc3sg]

Thanks!

Great video, Shall we make the same process in NodeMCU board(ESP8266) it has hardware serial as well right but not as ESP32. Will tell me the process if possible. I have tried but getting some errors in the code. Thanks in Advance...
