RE: Buttonless DFU Service characteristics values

Hi Edvin,

I'm connectinf with nRF Connect Mobile (Android).

I think I have found the reason of my issue.

In the file ble_dfu.c, I had done a copy-past of the function buttonless_char_pt_add in order to add two more function add characteristics "DFU Control Point" and "DFU Packet". I wrongly thought they were missing firstly.

I removed them and it works fine, I can now enter in bootloader DFU mode with nRF Connect phone and the Buttonless DFU Service.

I think there was a conflict with the control point cccd handle.

With my SDK 13.0.0, the application (ble_dfu.c) waits for indication enabled and not notification as I could read for other SDK version. So it's right to send the value 0x02.

Thank you.

Best regards,

Alan

Can you explain a bit what the issue is and what you do that causes the application to enter the on_write() callback?

The CCCD characteristic is the one that controls whether notifications are on (0x01) or off (0x00) (or indication = 0x02, but that is not used in the bootloader).

What are you connecting with? nRF Connect? Desktop or Mobile?

Does the log from the other device tell you anything?

Best regards,

Edvin
