BLE Appearance

[Mihir Tailor]

Hello,

I am using SDK 12.3.0 on nRF51822 development board and nRFConnect app to scan and connect the peripheral device.

When i changed Mouse icon by the GENERIC_THERMOMETER or any other icons in the example of BLE Peripheral Mouse, the mouse icon still present on the advertising screen.

Why icon doesn't get to change on the screen when we changes it in the code?

Kindly reply to my query

Thanks

Hi!

I tested this myself, and the icon changes when using BLE_APPEARANCE_GENERIC_THERMOMETER.

Are you connecting to a smartphone? If yes, what smartphone are you using?
Or are you using nRFConnect for desktop?

It sounds like this might be related to some caching issue.

Best regards,
Joakim.

Hello Joakim,

Thanks for reply.

I am using nRFConnect on my Moto G First Generation Smartphone to connect with my peripheral sensor device.

Thanks.

Did you connect/pair/bond to the example before changing to the GENERIC_THERMOMETER?

As I said, this might be caused by some caching issue on the phone.
If the device has been bonded to your smartphone, you should try deleting the bond information, turning the bluetooth on/off, restarting the app.
If the icon still doesn't change, I would try to restart the smartphone.

Let me know if you are not able to see the thermometer icon after trying the above, and we will see if we can find another solution.

Best regards,
Joakim.

Where should I define this? Where can i see all the other different appearances?

Hi!

The bluetooth appearance can be set using the sd_ble_gap_appearance_set() function.

A list of the different bluetooth appearance values can be found here, or in the ble_types.h file in your SDK.

In this thread, using the ble_app_hids_mouse example in SDK 12.3.0, this is done in the gap_params_init() on line 475 in the main.c file.

Best regards,
Joakim.
