Problem:

we have a ADV LOCAL_NAME_LEN_MAX with "HELLO" and handset can scan it

but after we try to change it and make it longer as "HELLO SENSOR" in BLE_PROFILE_CFG,

handset can not find it as Unknown Device.

Do u know how to enlarge the NAME length and where to clean build the header file?

It seems the length is less than 17 char but handset can not find it.

Is your application based on hello_sensor?

Maximum data length of advertisement packet is 31Byte.

hello_sensor application already uses 30Byte.

So please remove other like 128bit service UUID before adding characters to local_name.

Or keep local_name within 6 characters.
