There shouldn't be any way to affect the device name handle, it should be constant for a certain softdevice version, and as far as I know, all softdevice version up until now have had the name at handle 3.

To set the name, you should however use the sd_ble_gap_device_name_set() method instead of doing it directly with the handle, as that will be portable to all future softdevice version as well. The handle may however be useful when receiving a write to this characteristic.

Also, if you're advertising while changing the name, you have to make sure to set up the advertising data again, essentially calling ble_advdata_set() again, after having changed the name, since this can't be done automatically.

If you still have trouble, I'd be glad if you could upload your project, so that I can have a look. Feel free to create a support case for it if you need it to be handed in confidentiality.

As for looking on ble_evt_t, there shouldn't be any problems with this, but remember to not compile with -O3 if you want to be able to debug the code in a line-by-line fashion.
