sketch get stuck with LoRaWAN

[nichis]

Please check the library LoRaWAN.cpp, there is a problem with the debug print since the sketch get stuck if I close the serial monitor. If I disable the debug print (_DEBUGSERIAL = 0) everything works fine

@nichis which sketch did you run? ABP, TOAA, p2prx, ptp_tx? I've tried these sketch but didn't go to that situation. Or can you explain the reason?

[nichis]

I'm using a custom sketch.. However also trying with the OTAA, when I close the Serial Monitor no more data are received from my LoraWAN gateway. If I set #define _DEBUG_SERIAL_ 0 into LoRaWan.h everything works..

Of course have to be removed also the line while(!SerialUSB); into the default sketch

@nichis Hi, could you share some logs when run the sketch with debugs on?

@WayenWeng here is the output of my OTAA sketch:

@nichis, please use the api "transferPacketWithConfirmed()" test again and share the log.

@nichis It seems works fine with gateway. It can joined the network and get a network id. It can receive a confirmed message from RXWIN2 after transfer a packet. Is it possible some problems on gateway get raw data? And is it possible to show the original data on gateway? The only issue "+LW: ERROR(-2)" is case the firmware version is not the latest(2.1.16). You can update the firmware and solve it.

@WayenWeng thank you but the problem is not about receiving the data on the gateway. The problem is with the debug print since the sketch get stuck if I close the serial monitor of the Arduino IDE, and so if I try to execute the sketch without opening the serial monitor.

I had a similar problem and narrowed it down to the for loop in the transferPacket function. i was going from 0 to 254 in a loop without stopping. I fixed it by declaring it as int. From for(unsigned char i = 0; i < length; i++) to for(int i = 0; i < length; i++)
