End Devices (Nodes) Dragino

Hi, i got a problem with my dragino LSN50, i want to connect a analog sensor with 0-3v to analog port, but i cant get a usable adc value from lsn50

here is the user manual: http://www.dragino.com/downloads/downloads/LSN50-LoRaST/LSN50_LoRa_Sensor_Node_UserManual_v1.2.2.pdf

i connect the 0-3v sensor output to PA0

When the signal is 3v the console shows:
“ADC_CH0V”: 0.011

I solved the Problem with firmware update from 1.3 to 1.5 :slight_smile:
