I want to upload the flame sensor data to Thingspeak cloud. How can I use my Bolt board as an Esp8266 module to upload data to cloud ? Please provide the proper connection along with the codes.
There is no direct method which we can provide a solution for your problem statement. This is due to the following reason
Bolt although it has an ESP8266 module at its core , it runs Inventrom proprietary firmware, modification or overwriting of which will render your Bolt useless in terms of Its connection to Bolt Cloud.
But if you provide the specifications of your flame sensor perhaps I can provide an alternate solution to your problem using just the Bolt as it is or using Bolt with Arduino as the case need be.
