Voltage divider for Heltec Lora:
I found some problems. The default pin #34 for monitoring Heltec v3 external voltage is not working. It shows 0.55V all the time:
I contacted Ricardo Guzman for solution but he answered:
I found the solution myself. I just moved physically the cable to pin #19 and reprogrammed the interface:
Now everything works nicely:
A small note – to test how the sleeping function works, I connected a LiPo battery + a charger to the USB C port, and then I unplugged the charger. But… nothing happened. However, there is nothing wrong and you just need to be patient. It looks like the voltage status is being checked every 30 mins. So, after 20 mins (waiting time depends when the event happened inside of the 30 mins windows) the iGate turned off. Then I found a very nice info on APRS website:
So I plugged back the charging and I had to wait about 30 minutes to get the iGate Digipeater to be turned back on. It works perfect!!
My sample configuration:
Please note, all the voltages you see on Heltec display they are not a real time. They refresh every (I think) 30 minutes!
