OTA by peer

[zk017]

I have two ble boards（board A and B）, one for client(Board A) and the other serve as slave(Board B). now i want to use board A to upgrade the application of board B by OTA.  Board A is connect PC and can use com port to translate file.

Is this feasible? and what can I do? or where can find some guideline for it?

Hi zk017, 

Yes, you can use our nrfutil software together with a nRF5xxxx board on the PC side to perform OTA DFU of other nRF5xxxx devices. 

Best regards

hi, bjorn-spockeli, thanks for you reply. Yes I know the 51dongle can do this, but maybe I should explain my question in detail: the board A and B is designed by myself, and I want to know what should I do:  how to do on board A to realize the function , upgrade the application of peer(board B). 

I want to know is there any example of the code for this?

Hi, you can run a serialized application on any nRF5xxxx board,  see Serialization on the Nordic Infocenter. nrfutil uses the pc-ble-driver  on the PC side and then runs the serialized application on the nRF side.

We do not have any standalone application code that is both central with DFU support and peripheral. 

Best regards

Bjørn
