@paul-thornton Thanks for taking a look. I'll use the UART connection and write my own class to operate the radio. Cheers!

@jmarcelino I've tested this now (removed lte = LTE() and lte.deinit() ) and the peak is still there. The device goes into deep sleep, but like before the current rises quickly to about 200 mA for a couple of seconds before it goes into deep sleep. I also find it strange that it doesn't happen the first time the device goes into deep sleep, but all consecutive runs. The first time now, since I don't deinit() LTE the current is at about 200 mA and drops down to deep sleep. Then when waking up it is around 60-70 mA when measuring and then peaks to 200 right before deep sleep.

You do not need 0.5 ppm at least not for 125/250/500 kHz bandwidth.

@bigboy20769 I see at least two options: call the respective init methods in a try block call os.uname and check the type of module
