Hello everyone, I’ve been researching time synchronization for LoRaWAN recently. I’m using the B-L072Z-LRWAN1 development board from STMicroelectronics, and I want to achieve time synchronization between the board and TTN. I have thought of a few methods, such as using the LmHandler function LmhandlerDeviceTimeReq (although it appears that this function cannot be used because my board only supports LoRa v1.0.3). Therefore, I’d like to ask if there is a better method to achieve this, for example using CLASSB (although I don’t know how to implement it; could someone help me with this?)
