push: the best way is, you test first the steps by using a terminal better, you connect one ESP32 to a terminal and the second ESP32 to a terminal then you can "play" the steps you need later on AVR and you can make a protokoll. this protokoll then you write then later for the AVR / c code the AVR t...

AVR(1)<-UART->ESP32(1) <-WIFI-> ESP32(2)<-UART->AVR(2) :) this is the simplest way: take a look to the AT Instruction document You need on one side the SoftAP ( Accesspoint ) + Station Mode ( Client ) and on other side the Station Mode ( Client ) Your searchstring in docu is : AT+CWMODE you can set...

Not in this point. I have 2 AVRs and 2 ESPs : 1. AVR connected to ESP (AVR+ESP) 2. AVR connected to ESP (AVR+ESP) I need to make comunnication between 1 and 2 bidirectional. (AVR + ESP) <-> (AVR + ESP). Using AT commands I need to make communication between 2 AVRs. :) ;-) ok. i think you have conne...

Hi again :) May I ask you the another question? :) I`m trying to make comunication between two modules of ESP ( ESP<->ESP ). Actually I need to make comunication between two AVR. I need to get the data string through UARTs - Is it possibile ? What trasmission mode should I set? I need to use AT com...

The sample frequency is 6KHZ. We have 12-bit SAR ADC up to 18 channels.

Interesting would be still, all channels share this frequency or applies to everyone

hi guys

AT example on github

cause AT is provided as a LIB..

does this know / tested someone?

have started this on github too

Hi, I have been trying to get the AT Command Processor working with the sparkfun thing. Everything complies ok, and seems to flash ok, but I get an error from the serial terminal after a reset (see below). There is no response to <CR> or AT<CR> from the terminal. I have tried the Esp Idf current re...

hi only a thinking, have not tested just in time ( later time ) can we use uart0 as AT command port, too ? does it be enough to set it in the sdkconfig ? best wishes rudi ;-) yes we can ( fine with make flash monitor too ) 7.png you do not need any more USB Adapter or others. simple flash over the ...
