Issue:The node is not responding to Serial Port Tool or the Bootloader
Setup:
Server:
Details:The node was working normally, after I have configured it with TTN, it sent few messages to the TTN. After that it stopped working. I tried to read it is data through serial port tool, no response at all you can see the snaphshots. Then I tried the procedure to reload firmware using the STM32CubeProgrammer after connecting the boot jumper and the situation is the same. I am attaching both tools response. Athough the PC see it as a Port and it can connect to it but no further response.
Is your laptop connected to the other end of the USB?This could be caused by a lack of electricity.You try to replace a cable or PC, and press the button to restart and reload the BootLoader!
Yes, the problem is that I have two boards, one of them is booting and working normally using same USB cable, the other is not. Should I connect or disconnect the battery while Reseting or Loading the bootloader?
BTW the device was working normally, I have reset it, loading the bootloader, connect it to the gateway, and configure/connect it to TTN. After connecting it to TTN by 1 hour, it stopped responding to any command.
** it stopped responding to any command.**
Is this the result after you loading the bootlader and firmware?
And tell me the version of the BootLoader and firmware?
I mean it stopped responding to commands after joining the TTN. The bootloading was done few months ago, but after it stopped responding I tried to reload firmware. Version 3.0.0 H
Thanks Nicholas
Yes sure if you scroll up in the thread you could see the board jumpers config and the error messages that I got during boot loading and serial communication.
Yes sure, the device was configured and connected to TTN. But after a week when I tried to change the application Application ID, I could not reach the device using any of rak serial tool or bootloader.
