We've been collecting location data on a few units and have found that: - the HDOP looks suspect (starts at 0, sometimes just increments, bounces around a bit) - the altitude varies by 10's of metres - the location move...

Seeeduino LoRaWAN no USB port detected after uploading sketch

Mistaking the on-board ATSAM for the RHF76's STM32, I copied the sketch found here to attempt to read the UUID: http://stm32duino.com/viewtopic.php?t=245 After uploading the sketch...
