How to change the device name?

[Alice]

Hi all,

I'm using the PCA10028 and S130 based on SDK9.0。Now I have save the device name(such as "My device") in the flash,so the 51822 can read the device name and update the name when powered up or reset everytime.I have use sd_ble_gap_device_name_set function to set the name in the gap_params_init function reference to the project in SDK.Also I can see the value of err_code variable is zero when call the sd_ble_gap_device_name_set function.The gap_params_init is called in front of advertising_init function.But the device name cann't be updated.

Could anyone tell me how to make it?Thanks.

Hi. You will need to call ble_advdata_set() after you have changed the name with sd_ble_gap_device_name_set(). See this thread for more info.

I have attached an example that uses a timer to change the name of a device every other second. It uses SDK V9 and Softdevice S110 V8. Search for // NORDIC in the example for comments.

Example.

So this line prints the correct device name:

printf("change device name: %s",(uint8_t *)&at_com_data.device_name[1]);

?

And you are 100% sure that the first character in the device name is 'N'?

Also in the else-statement you don't call ble_advdata_set() so you will not be able to set the name to DEVICE_NAME.

Could you post your complete main.c file?
