Parallel device update using Nordic DFU library

[matt17]

Hello,

We recently implemented DFU on Android for nRF51 and nRF52 devices using the Android DFU library from GitHub. It works great, and we would like to see if it is possible to perform DFU in parallel. We tried a simple multi-threaded approach to DFU multiple devices at once, but we found that the DFU service waits for each device to finish updating before starting the update for the next device.

Is there a way to perform DFU in parallel using the existing Android library? If not, is there a reason/limitation that prevents parallel update, or is this something Nordic or our team can implement?

We appreciate the help!

Thanks,

Matt

Hello,

The dfu on Android has been implemented as intent service. There can be only one instance running as a time, but you may extend the DfuBaseService as DfuService1 and DfuService2 and should be able to run them in parallel.
