Problem uploading firmware on RAK4630

[Miliks (Liudmila)]

Hello, i’m trying to upload the example code to RAK4630 using Arduino IDE. it compiles successfully (even though extremely slow), but when i try to upload it, after a while i get the following log:

2024-05-29 09:50:46,979 Using board at serial port: COM7
2024-05-29 09:50:47,011 Sending Application image.
2024-05-29 09:50:50,666 No trigger interface found for device with serial number: 47DCAD1B5860EDD9, Product ID: 0x0029 and Vendor ID: 0x239A

2024-05-29 09:50:50,667 Serial: Waiting 500 ms for device to enter bootloader 1/10 time
2024-05-29 09:50:55,766 Serial: Device is either not in bootloader mode, or using an unsupported bootloader.

and then

pc_ble_driver_py.exceptions.NordicSemiException: No ping response after opening COM port
[27400] Failed to execute script '__main__' due to unhandled exception!

so i never eble to flash any new firmware on it.
i followed the tutorial to update a bootloader through the USB cable and terminal. And it’s the:
UF2 Bootloader 0.4.3
Model: WisBlock RAK4631 Board
Board-ID: WisBlock-RAK4631-Board
Date: May 20 2023
Ver: 0.4.3
i tryed to send AT comand from Arduino Serial terminal, but the is no response.
Could you please help me to understand how i can use the device?

Welcome back to the forum @Miliks

What BSP did you use to write your application? RUI3 BSP or Arduino WisBlock BSP?

Could it be that you trying to upload a RUI3 application to an Arduino based RAK4630.

@beegee

RUI3 BSP

could you please tell me how i can check it?
i have installed both package_rakwireless.com_rui_index.json and package_rakwireless_index.json on board manager preferences

[beegee (Bernd Giesecke)]

You checked the device itself already, it is Arduino BSP.

Inside ArduinoIDE in Preferences, what "Additional Boards Manager URLs: " are you using?

[Miliks (Liudmila)]

both
should i remove the RUI one at this point?

[beegee (Bernd Giesecke)]

If you have both, then you have to select the correct board in Board Manager:

You need to choose RAKwireless nRF Modules ==> WisBlock RAK4631

This one DOES NOT WORK with the module you have:
