How to I transmit or accept data from arduino uno.
And once accepted how do i upload and save it on my bolt cloud
connect Arduino Rx pin to bolt iot Tx pin & bolt iot Rx pin to Arduino Tx pin . common ground & 3.3v between arduino & bolt iot module. & when you are uploading the code from arduino ide to Arduino development board, make sure that your Rx & Tx connection between arduino development board & Bolt iot device is open. otherwise you can’t upload the code. It will show error.
Please go through the following project to understand how to use the Bolt WiFi module with Arduino
