Hi,

I am doing a "Bluetooth low energy Advertising, a beginner's tutorial". One of the challenges is change the advertising name type, the provided commands are same as yours,

init.advdata.name_type               = BLE_ADVDATA_SHORT_NAME;
init.advdata.short_name_len          = 6;

However, the advertisement name still showed full name as before after I modified the code as above, compiled and downloaded it to my nEF52-DK. It is did not make sense.

Please take a look at this question.

If you can live with not advertising the full name, you can consider advertising just parts of the name instead, for example like this:


    advdata.name_type               = BLE_ADVDATA_SHORT_NAME;
    advdata.short_name_len          = 10;

This will include only 10 bytes of the name in the advertisement package. The other alternative is to move some data to the scan response, by passing a second ble_advdata_t to ble_advdata_set().
