onDescriptorWrite error 128 , Error (0x80): GATT NO RESOURCES #482

My app is using your lib ver:2.5.1 and it works normally, but sometimes, my app(that run on android 13) can not connect "lock device" with the error: 

bt_stack: [WARNING:bta_gattc_act.cc(365)] bta_gattc_open_fail: Cannot establish Connection. conn_id=000000. Return GATT_ERROR(133)

After a few days research that issue, I think that is an android 13 BLE problem. https://issuetracker.google.com/issues/242755161?pli=1. On the other hand, I see the latest lib release is 2.6.0. so I decided to update my app with the latest version. After upgrade. I tested my app and I see the error below that was never found in ver 2.5.1:

But after facing the error, my app still continues to work normally. So could you please let me know what happen with my error above? Thanks

Regarding the first issue, when you do retry(times, delay) it should retry to connect if you're also getting this error in the library and it can handle it.

The other issue, is it present after restarting Bluetooth? How do you reproduce it?

for "onDescriptorWrite error 128 , Error (0x80): GATT NO RESOURCES" I'm facing it sometimes, my app has many steps that need to be done before app can communicate with device as below:

  1. generate Digital Signature
  2. verify Digital Signature
  3. verifyDevice Cert
  4. send Key And Salt
  5. add access codes

In each step, we call the methods: SetIndicationCallback EnableIndication WriteCommand

Then I faced the error after step 4.
