Hey Sigurd, I found it. And updated to v2.5.0. Thanks.

uint8_t send_data[3] = {0};

send_data[0]= 0x01;

struct bt_gatt_write_params write_params =

{

//.data = 0x01,

.data = send_data,

.length = 1,

.func = write_callback,

.handle = 0x0010,

.offset = 0,

};

err = bt_gatt_write(conn, &write_params);

V2.3.0 Sorry, I should have mentioned that. I don't object to updating. I'm developing on a nRF52840 dev kit and will be using the Fanstel BT840F module. Our system will use a Debian board to interface with it, thus the overlay. Not needed in the test project. Thanks again.

Hi!

Thanks for the project, I will test it and see why it fails to put the device in DFU mode.

I tried building the project using NCS(nRF Connect SDK) v2.5.0, but I got some build errors. I'm guessing this project was originally written for another version. What version of NCS did you use?

Modified for DFU service 0xFE59 on 52840 client. I have a target address hard coded. Fails to put into DfuTarg mode??? Thanks for any ideas.

Hi Sigurd,

I found it works ok from my phone also. It acts like maybe a memory issue? Maybe a config problem? I cant find this flag: config BT_RECV_CONTEXT mentioned in the description for bt_gatt_subscribe().

I also found all the permissions reporting 0x0000 from bt_gatt_dm_attr_next() for all services, including the NUS. But that works, I'm able to read and write to the NUS handles in the central_gatt_write project.

And like I mentioned, using NULL in bt_gatt_dm_start() fails to discover anything but the base service.

What do u suggest next? Thanks for the help.

Bob

Hi!

Had a look at the sniffer log:

This one looks a bit strange.
Testing and comparing with nRF Connect for mobile, I see this value is set to 01 by the master device
