I dont use GPS module (not soldered).
I removed power LED, software disabled LED1 & LED2. Now current consumption of board is:
Hold the RESET button - 39.5 mA;
Wait mode - 6.5 mA;
Transmit of packet - 68.8 mA;
Two short strange consumption after transmit - 22.2 mA.
Now drop of voltage is 70 mV per one day (18650). I would very much like to get values in microamperes in sleep mode.
I did as you wrote, but I can not put the device into sleep mode.
Are you able to share your code? Or working example, please.
With best regards.
