Is there any way to change the BLE device name while the CC2640R2F SimpleBLEPeripheral program is running?

Hi,

The BLE device name is given by the content of the Advertising data and/or the content of the Scan Response. As a result, if you change the content of these two data sets, the name of the device will change.

A few caveats to keep in mind:

some phones keep in cache the name of the devices and only update it if a new scan response is received
some phones keep the name of the devices as long as the BLE cache is not manually erased
to update the content of the scanRsp or the AdvData you have to 1) stop advertising 2) wait for advertisement to be stopped 3) change the data you want 4) re-enable advertisement

I hope this will help,

Regards,

Hello Clement,

Thank you for the reply. Do you have an example or list of commands to be able to update the content of scanRsp?

You can change the content of the Advertising data and/or the content of the Scan Response directly to make it.

Hello YK Chen,

In my application, I am using SPP to connect and then change the BLE advertising name as requested by the client. Do I need to take any particular steps to change the scan response and advertising data? In my application, the client can request to change the advertising name and I should be able to do that while my service is still running.

There’s no original sample codes for this. I suppose you need to add your own custom codes to achieve that.
