Hi
Is there anyone using a ESP8266-01 as a shield, lots of set ups on the web, some refering to using a “Token” plus lots of different ways to connect but I still have not succeeded.
There seems to be no updates on the subject since 2018 on the Forum, I have followed the suggested set ups within by to no avail.
An advice appreciated.
Regards
Ian
this is the code you need to use for esp as shield Cayenne-MQTT-Arduino/ESP8266Shield.ino at master · myDevicesIoT/Cayenne-MQTT-Arduino · GitHub
Though it is not stable with arduino uno.
Hello Shamik
Many thanks for your reply, I have used the sketch using a UNO with no success and have burned a couple of ESP-01’ s in the process, I did not use a regulator on the RX line and so put 5V through the ESP… learn by your mistakes I think is the quote.
Onwards and upwards onto using a Mega and see if I can achieve success, I have a ESP MCU 12 Running quite successfully so am only experimenting with the shield idea.

i have been through this also, it is good to learn from our own mistake.
