@agirolami87 I am not quite sure about it.
Join command from arduino.
* No LED2, LED3 activity.
* not able to join networks, even when i should be in range.
Join command from onboard USB/CH340G
* LED2, LED3 both show activity
* not tested yet if i am able to join networks this way, did not have it on the road yet with usb->serial console.
In both cases, response is the same:
Why is the behaviour of LEDs different? Why can I send commands, receive 'OK' but not able to communicate with LoraWAN when i'm using arduino serial port?
Never mind. I see in the schematic that LED2 and LED3 are the CH340G TX/RX leds.
Looks like your connection to RAK Support Center was lost, please wait while we try to reconnect.
