Dynamically change the read / write security operation

[Brian Chang]

Hi,

Is it possible to change the security option of  characteristic read or write?

For example , we initial the characteristic as JUST_WORK? Then change it to SEC_OPEN in some of case after disconnect?

Thanks

SDK version : 15.2

Device :52832

Hi. 

It's not possible to update Services and characteristics on the fly. You need to disable then enable the softdevice and re-initialize the new BLE services.

Please look at this previous ticket:
