ok but that example uses SS, so I dont know if Rx-6-Uno is connected to Rx on the esp01 module. In my example I have the nano Rx wired to the ESP01 Tx and vv.
The thing is I want to understand what the difference is. I have been going thru examples of using the ESP01 module:
- Uploading sketch to nano that sends AT commands to the esp01 to post data
- Uploading sketch to nano that uses library to post data
- Uploading sketch to esp01 directly that posts data to the web
And I seem to have my 'lions crossed'
