rakwireless / rak4600_arduino Goto Github PK

I try to find the PIN 18, but it is already grounded! I am using RAK4600 Module and not the breakout board!
I am not able to flash the code from Arduino IDE using serial.
Also, I tried using J-Link(select as a programmer and then Upload using programmer) it flashed, but no results!
If I am putting RAK firmware hex via J-Link again, it works fine!
But, when I flashed code via Arduino by 1) Serial update is not working
2) J-Link is also not working

I am stuck!

I tried to use delay(Sleep_Time); But the not that effective!
But I found that I need to use os_runloop_once(); to able to handle lmic events.
The current measured is 2.45 mA.
How I can put the module in better sleep mode - the one which you have mentioned in electrical characteristics - 2uA???

I have a rak4600 with firmware version 3.4.0.14.
I send sleep mode and it work well until the chip reboot, in 2 to 3 minutes.

Do you have some ideas , how to avoid it?
