Seeeduino Lorawan "Can't upload firmware"

Hello,
I am having issues to upload the a new firmware to the seeeduino lorawan board.

I did the following steps:

  1. Upload of the following sketch to the board:

// Update firmware to RHF76-052AM
#include <Arduino.h>
#include <SoftwareSerial.h>

SoftwareSerial mySerial(45, 44); // RX, TX

void setup()
{
mySerial.begin(115200);
Serial.begin(115200);
}

void loop()
{
while(mySerial.available())
{
Serial.write(mySerial.read());
}
while(Serial.available())
{
mySerial.write(Serial.read());
}
}
2. Open extraputty and connect to the board as described on the seeed studio wiki (http://wiki.seeedstudio.com/Seeeduino_LoRAWAN/). I saw the char ā€˜Cā€™ printed in extraputty. I then uploaded the file over Files Transfer > Ymodem > Send. The Transferring File dialog opens, the RX/TX LED started blinking, and the software started to upload the firmware.

Unfortunately the upload process did not stop. See picture below.

Please can somebody help me with my issue?

Thanks in advance
Sebastian

Try a few times, are they all failures? @letsab

I will test it next Monday, and if there is a problem, I will fix it

Hello Baozhu,

Thanks a lot for your reply. How did you go on Monday? I tried multiple times with different boards, but it is not working.

Thanks
Sebastian
