Jut to get an idea of what your set up is:
An easy mistake is to remove the factory given AT from Seeed by flashing over it, as an FYI.
I flash the board with a STLINK-V2 clone I am under Ubuntu18.04 with STM32CubeIDE and program with STM32Programmer
To give more details, my board was with AT firmware and first I tried flashing the "official" STM32 lorawan stack(over it). And I could do this several times successfully. Then I decided to use the source from here which is dedicated to LORA-E5 mini and it worked fine but only once :-) I am a newbie with STM32 architecture...
@Sebelectronic did you fix the issue? I am experiencing the same issue now. I have followed the tutorial and flashed the lora-e5 with the LoRaWAN_End_Node firmware. Now the board cannot connect to stm32cubeprogrammer... I use v3-minie programmer.
@miroslavpetrov , sorry for my late answer but I didn't try to fix my trouble. Did you fix it?
@Sebelectronic I use genuine STLink V3-Minie. It turned out that this little sh** works 100% of the time with only one of 10+ tested USB-C to USB-C cable and it works fine ONLY if the cable is plugged in a certain way(if I reverse it it doesn't work).
Hi, I have followed your instructions until the end, compile the soft without problem , program it fine. But now when I want to program the LORA-E5 Mini again the board isn't detected by the programmer. I've tried pressing reset and boot push button without results. Any idea to help me to save my board? Thank you
