OK,
Kind of a working, BUT then the USB generally do not work most of the time – and no serial logging is possible and to upload a new code is a bit tricky – I need to press reset about 1 sec before the upload to be able to actually upload the new code …
any suggestion how to use the low power lib and in the same time to be able to upload new code and log in the serial while not sleeping ?
e.g. I want to sleep 10 msec , do some measurements, sleep again 10msec etc.
also dies the millis(); function will return the correct value or need to be adjusted with the sleep interval ?
device is Feather 32u4 with LoRa
