DA14531 Name Change Service/Characteristic

Daeolt

I was curious if there's a characteristic to change the GAP device name.

I know there's one to see the name, but I didn't see one to change the name. Is this one I'd have to manually create or is there a simple way to do so?

Thanks!

    Hi There,

    Thank you for posting your question online.
    Yes, it is possible to change the Device Name. 
    I worked on the ble_app_peripheral example with SDK v6.0.18.
    I created a custom characteristic for the Custom Service 1.
    On user_custs1_impl.c file:

    void user_svc1_dev_name_wr_ind_handler (ke_msg_id_t const msgid,
                                      struct custs1_val_write_ind const *param,
                                      ke_task_id_t const dest_id,
                                      ke_task_id_t const src_id)
{

	char new_device_name[NEW_DEVICE_NAME_LENGTH] = "\0";

	memcpy(&new_device_name, &param->value, param->length);

	device_info.dev_name.length = (strlen(new_device_name) <= GAP_MAX_NAME_SIZE) ?strlen(new_device_name) : GAP_MAX_NAME_SIZE;

	memcpy(device_info.dev_name.name, new_device_name, device_info.dev_name.length);

	
}

    On user_peripheral.c file:
    void user_catch_rest_hndl(ke_msg_id_t const msgid,
                          void const *param,
                          ke_task_id_t const dest_id,
                          ke_task_id_t const src_id)
{
    switch(msgid)
    {
        case CUSTS1_VAL_WRITE_IND:
        {
            struct custs1_val_write_ind const *msg_param = (struct custs1_val_write_ind const *)(param);

            switch (msg_param->handle)
            {
                case SVC1_IDX_CONTROL_POINT_VAL:
                    user_svc1_ctrl_wr_ind_handler(msgid, msg_param, dest_id, src_id);
                    break;
								
                case SVC1_IDX_DEV_NAME_VAL:
                    user_svc1_dev_name_wr_ind_handler(msgid, msg_param, dest_id, src_id);
                    break;
                    .
                    .
                    .

    With the SmartBond App I connect into my device and I can change the Device name like this:

    Quick follow up to this actually: what compiler is required for these changes?
