RE: GAP "Device name" handler value

Yes, that's what I exactly mean. The simple difference in current SDK:

instead of mentioned

p_evt_write->context.char_uuid.uuid

now it looks like

p_evt_write->uuid.uuid

(from ble_gatts_evt_write_t typedef)

Compiled and tested, the solution works fine. Thank you!

Hi!

[quote user=""]When my device received name change request from central, I can catch this event (for updating device name in FDS) by callback *_on_ble_evt, event ID BLE_GATTS_EVT_WRITE and write handler 0x03. Value 0x03 was hardcoded in my firmware, but I suppose it looks like bad code style.[/quote]

I would recommend doing it by checking the UUID written to. Device name has it's own UUID, so if you get a write to that specific UUID, you can add logic for storing the name as well.

Here's a rather old (but still valid) thread on the same matter, which includes code on how to filter out this specific event: https://devzone.nordicsemi.com/f/nordic-q-a/10539/device-name-change/39211#39211

Let me know if you have any issues implementing this.

Cheers,

Håkon
