error on writing descriptor (133)

[nourmed]

I am getting the error "error on writing descriptor (133)" when I connect the device (esp32 as server) to an android phone only when I try to read Temperature values on pairied status or not while on Iphone it works just fine ,can't find the reason why

The only descriptor that nRF Toolbox for Android reads is for the Service Changed characteristic. On bonded devices it ensures that SC indications are enabled. iOS API doesn't allow to read CCC descriptors, so we don't do this on iOS. iOS also deals with the SC indications correctly, so there's no need for any workarounds.
Make sure the CCC descriptor under Service Changed characteristic is readable.
