Strange characters in bluetooth peripheral name

[Robert]

Hello,

I have a strange issue, when I set the name of the bootloader dfu peripheral name, inside of sdk_config.h

#define NRF_DFU_BLE_ADV_NAME "DfuTarg"

When I scan for peripherals with all my phones, the name is correctly spelled DfuTarg

But when I do the exact same procedure with my Sony Xperia E6633 the peripheral name is "DfuTar[?]" with a question mark at the end instead of a "g". See image:

All other peripheral names (that are not set with NRF_DFU_BLE_ADV_NAME) looks as good as usual.

What might be the problem? Thank you!

I have discovered that Sony Xperia E6633 won't handle more than 6 characters when we set the peripheral name through -> 

#define NRF_DFU_BLE_ADV_NAME

We simply set the length to a name of 6 characters

Hi Robert,

If this only occurs with the Sony mobile, it does sound like there is an issue there.

Could you maybe test with another example like "ble_app_uart" to confirm that the application on the peripheral side doesn't matter regarding to this issue?
