I’m trying to connect Bolt with NodeMCU to collect analog values or to perform digital read, write operation. I also want to use python to perform operations.
If you have a Bolt WiFi module and a NodeMCU then the procedure for interfacing them together is the same as interfacing an Arduino with the Bolt WiFi module. You just have to make sure that the UART pins of the NodeMCU are connected to the UART pins of the Bolt WiFi module as you would do for an Arduino UNO.
You can go through the following project to understand how it is done.
