after bonding, then call writeCharacteristic, it fail #479

Closed eaglewangy closed 1 year ago

eaglewangy commented 1 year ago

After bonding, the variable operationInProgress in file BleManagerHandler.java remains true. So calling api writeCharacteristic will fail. It need to reset this variable after bonding.

What phone and OS version are you getting this issue?

philips77 commented 1 year ago

Does your device bond after connection or as a result of Insufficient Auth error on GATT operation (read / write)?

We tested on Galaxy S9(SM-G9600/DS), XiaoMi Mi11 Ultra. It should be a general issue

It bonded successfully. No error reported

I was asking when during the connection do you bond to the device. Is the bonding requested from the device side just after connection, or when the central tries to access an attribute, or by a request from the phone?

The process is:

  1. connect to a bluetooth device.
  2. call writeCharacteristic to send some data.
  3. call ensureBond
  4. call writeCharacteristic, then failed. cause the operationInProgress is true
