pc-nrfutil on embedded OpenWRT

[Chris]

Dear All,

so we have an embedded SoM running OpenWRT and I was wondering if I can make use of nrfutil even if not connecting a nRF52 via USB but via UART.

What I want is especially this:

For example, enter the following command to perform a DFU procedure of the file app_dfu_package.zip over BLE, using an nRF52 connectivity IC connected to COM3, where the remote BLE device to be upgraded is called MyDevice:
nrfutil dfu ble -ic NRF52 -pkg app_dfu_package.zip -p COM3 -n "MyDevice" -f

does this also work if NRF52 is connected to physical COM, not only VCOM/USB?

Hi Chris, 

 

Yes it should work. From the nRF52 side, there would be no different it's just UART. But make sure you use the same UART pins and use HWFC (I don't remember 100% but most likely, please check the connectivity firmware)

Hi Hung (or Bui? Always confuses me as it is different, I think),

thanks for the reply!

I will check if I can compile it for arm as the python package is precompiled for x86/64 ;)
