USB BLE Dongle with serial bootloader

[Miri]

Hello

i need to make BLE Dongle (reproduce without having documents, just a page how to update Firmware)

i need to be able to programm a .hex file i have via nRFgo Studio - nRF5x Bootloader - DFU using serial bootloader as a Application, 115200 Baudrate using flowcontrol.

i tried with the NRF51 Dongle but it didnt work. as a control unit i would be able to comunicate with the dongle via a serial Terminal.

is it possbile with the NRF52840 Dongle, or do i need to make Hardware modification to do it? what kind?

please help

thanks a lot

Hello Miri,

 

i need to make BLE Dongle (reproduce without having documents, just a page how to update Firmware)

 Do you mean a 3rd party dongle that you don't know what is programmed with? Or do you have access to the bootloader source code?

 

is it possbile with the NRF52840 Dongle, or do i need to make Hardware modification to do it? what kind?

 If you want to reprogram the nRF52840 dongle from Nordic Semiconductor, you need to use nRF Connect for Desktop -> the Programmer application. You can not use nRFgo Studio with this dongle.

Best Regards,
