How to change device name in advertising data?

[riceman0]

I'm running the ble_peripheral\ble_app_uart example on my nrf52832, it works great.

However, in main.c there is this line:

#define DEVICE_NAME "Nordic_UART" /**< Name of device. Will be included in the advertising data. */

that corresponds to what I see as advertising in my "BLE scanner" app on my phone.

When I change this DEVICE_NAME to another string, and rebuild my application, I cannot seem to get the name to change in the BLE scanner.  I redownload, cycle power, restart the App, it actively advertises to my app, and it's the same name.

What is it I don't understand about this?

Thank you.

Try turn bluetooth off on your phone then turn it back on.  This will clear the device cache in your phone.  Other option is to connect to it. After that the cache will be updated with the new name.

Thank you for the answer... I have no idea what was happening but this just started working.  That DEVICE_NAME is indeed the thing to change.  It seems like it wasn't reprogramming when I thought it was.  Sorry for the trouble, and thanks again.
