getting read characteristic CCCD descriptor not writable

[CodingWithTashi]

Thanks for the great example app, I am getting this issue when I disable and enable the bluetooth first time, subsequent connection are working fine.

Here is how I go the issue

1. turn off bluetooth
2. turn on bluetooth and connect to ble (Error will come)
3. try reconnecting while bluetooth is on (Than it is working)

Here is what I tried

1. Add delay after bluetooth is turned on, yet still getting the same issue
