Since it is not an Arduino, nor a ESP8266 standalone board… you need to prepare your IDE for it. Once you have made it possible to program the Teansy in the Arduino IDE, then you will have to experiment for the best Arduino board option to chose in both the sketch builder and App. Although if using just Virtual pins, then it really doesn’t matter… just use these libraries…
hello,
I’m new to arduino. I have the same type of work. We have a board purchased from https://www.tindie.com/products/cburgess129/arduino-teensy-v44-with-wifibluetoothnrf24l01/
which need to be used to send data to cloud via esp8266. but as said in above links esp8266 just acts as serial to wifi transciever.
Could you please share your code for sending data from teensy via esp8266.
BTW, the above specified link for teensy blocks the visitors to site.
