i am not sure what this is about. can you add #define CAYENNE_DEBUG in your second esp and open serial monitor. check what is the output and share here.

Hi, Thanks
Ok I have flashed the esp01s with just a blink sketch.
That is working so what code do i need to flash them with so that they connect to the dashboard of Cayenne. Mine is always saying waiting for board. If you could point me in the right direction .

Thanks again

are you using esp01 as shield or as a standalone?

5

as a standalone

uncomment #define CAYENNE_DEBUG

Thanks .That worked straight away.
If I wanted to use an esp-1 connected to an arduino to give the arduino wifi connectivity. what sketch is that ?

the sketch is recommended for arduino mega Cayenne-MQTT-Arduino/ESP8266Shield.ino at master · myDevicesIoT/Cayenne-MQTT-Arduino · GitHub
you can find all the connection example codes in here Cayenne-MQTT-Arduino/examples at master · myDevicesIoT/Cayenne-MQTT-Arduino · GitHub

It sounds like you are using the same MQTT credentials on each device. It kicks your first one off and never connects to the second.

Depends on what you are looking for, if you don’t need this much pins you always have two in the esp01. Other than you will need to connect them by serial.
Look the YouTube for good examples, this is the best way to know good ideas and perform them yourself
