How to using nrfutil in OpenWRT to do the UART DFU to nRF52832

[OPQ]

Hi,

I use OpenWRT and nRF52832 to develop a BLE gateway, the nRF52832 connected to OenWRT through UART. Now,we need the uart serial DFU of nRF52832, and I found that nrfutil can achieve this on Ubuntu platform.

So I think I can install the nrfutil to my OpenWrt board,to achieve serial DFU,and I try to use the pip3 install,but I got an error No matching distribution found for pc_ble_driver_py>=0.14.2 (from nrfutil), I already upgrade my pip3 to 20.0.2, python 3.7.6.

Could you please give me some suggestions?Thanks!

Hi,

It seems you need to install pc-ble-driver-py manually, not via pip, since it is not distributed for your ARM platform. This also means that you must build the pc-ble-driver binary for the target CPU on the OpenWrt device. We do not have any cross compiler configuration for the pc-ble-driver so it may be a bit of work, but you can find instructions for building the pc-ble-driver here. The pc-ble-driver-py repo is here.
