4 years ago From what I know this module does not have the battery sense, thus resistor divider connected to input 35 or 36 like for example the older version of TTGO T-Beam. Or maybe it has ? It could be as well connected externally: thus from two 100k resistors from the battery terminal to GPIO #36.

4 years ago Thank you very much, it works!
Just one more question, sorry... Can I change the time zone? (It is here utc+2h)

commented
4 years ago Did you connect the resistor divider to pin #36 and it shows the correct voltage ? Time zone on the OLED ? No, it is always UTC time, thus "Z" at the end.

4 years ago Yes, i did connect 2 resistors from battery port to GPIO#36, and now, i can see the correct voltage and percent.
"Time zone on the OLED ? No, it is always UTC time, thus "Z" at the end." Oh, so I can understand what the "Z" at the end. :D

4 years ago Great, thank you for the picture. The percentage is based on the battery voltage and the relation is simplified: anything above 4.1V is considered 100%, anything below 3.6V is considered empty and in between the two the conversion is linear.

4 years ago you do not need to solder anything, the Battery-sense-pin changed to gpio37 also you will have to switch on the power for output (gpio21) schematica found at https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/blob/master/SchematicDiagram/WiFi_LoRa_32(V2)/WIFI_LoRa_32_V2(868-915).PDF changed a proc.cpp in _static void ReadStatus(OGNPacket &Packet) :
#ifdef WITH_ESP32
// Packet.clrTemperature();
#ifdef WITH_HELTEC_V2
uint16_t BattVolt = 1.6 * BatterySense(); // [mV] measure battery voltage
#else
uint16_t BattVolt = BatterySense(); // [mV] measure battery voltage
#endifchanged hal.cpp (with some cleanup because it was bit confusing):
header is now sorted by boards :

#endifHi I tested the changes today, but the gpio36 still needed the resistor divider. Then you sent the correction (in section ADC), and now it works perfectly. Tomorrow I'm doing an outdoor test. Thank you!

4 years ago Sorry, it rained for 2 days. I did an outdoor test today. The display shows battery data OK, BMP280 data OK, GPS data OK. But the tracker did not appear on the map even next to the reciever. Although http://wiki.glidernet.org/esp32-ogn-tracker says "With Heltec V2 Board the parameter FreqCorr by default is ok (0), do not change.", after i set FreqCorr to -20, appeared the tracker on the map. So everything is perfect! I have a little problem ... When the battery is fully charged, the charge indicator LED will continue to light. Is this controlled by software or the panel? This is a 3.7V Li-Po battery, I will try it with an 18650 Li-ion battery. Thanks again for your help!
Hi,
I use Heltec Lora 32 v2 with Oled. I tried it with LiPo and Li-ion batteries but the display show 0% and ~0.3V (+00.0mV/min). The device runs on battery well and charges from usb.
Thanks!
