Nordic android app(nrf connect) is not displaying writable caharacteristic of buttonless dfu, which I am able write using Master Control Panel(PC).

[raju]

I am developing a android app for firmware update on my device. I used buttonless dfu example to switch from application mode to bootloader mode, I write value 0x01 to the characteristics via MCP by PC, but the same thing is not happening with nordic app, writable characteristic is not displayed in nordic app. How to get it displayed OR how to write to that characteristic using android app?

Hi Raju,

this is a known issue with the buttonless dfu example. The characteristic does not have the write permission, please see this answer.

I also suggest that you take a look at the other reported issues with the buttonless example. You can find them in our list over the known issues with SDK v12.x.0 ,here is the link.

Best regards
