I have been working in Stm32wle5jci6,im trying to integrate My I2C code with lorawan code package downloaded from github. I had tested with Macros in that case the data was pushed in Chripstack, but whenever i try to connect the sensor i am unable to read the sensor data. Note : im using HTU31D sensor and its working.
Solved! Go to Solution.

Hello @Nani96 ,
Did you manage to get a communication with your board?
When you debug your project, where the code hangs/stop?
Maybe need check your device configuration.
It will be better to attach your code and error message, this will help community users to help you.

hi, my Get_temperature function always reads 0 if i tried to implement the sensor code in lorawan package.
can any one tell me what was the issue with the code. Im transmitting data in cayenne format.
