B-L072Z-LRWAN1 lower bandwidth and spreading factors
I have a couple of these B-L072Z-LRWAN1 modules and I am trying to get comms at lower bandwiths and higher spreading factors.
I am using the DISCO-L072CZ-LRWAN1_LoRa_PingPong example as my starting point and I can get the modules to communicate but when I go below 62500 for bandwidth I cannot get any comms.
I understand the the TCXO is required below 62500 but I cannot for the life of me find where the code actually enables the TCXO for the semtech sx1276 module. The sx1276 library takes a pin to control the TCXO and the registers are mapped to enable the TCXO but it never seems to get enabled anywhere.
Can anyone help me figure this out?
