ios 14.2 app disconnect with a peer ble device using BlueZ 5.50 sometimes #67

Closed lirengen10 closed 3 years ago

lirengen10 commented 3 years ago

Dear Sir,

I am using BlueZ on my ble device(Linux 4.4), recently, after I upgrade BlueZ to 5.50 from 5.47, then ios app would disconnect with my ble device after click accept "request paring" at iphone sometimes, but it works fine when my ble device used BlueZ 5.47, and I saw the difference is that ios would show "request pairing" popup ui when connect to device with BlueZ 5.50, but there is not "request pairing" UI if connect to ble device with BlueZ5.47 .

From the log, looks like it is related to long term key secure connection, how to disable the "request pairing" popup UI of ios at BlueZ5.50 ? just like disappear "request paring" UI at BlueZ5.47. Thanks in advance.

I have the same issues，Whenever I connect RPi with the app on my ios phone, I get the following error：

[Callback]centralManager(central,didDisconnectPeripheral:peripheral,error:Failed to encrypt the connection,the connection has timed out unexpectedly.)

Vudentz commented 3 years ago

I wonder if this is related to having battery profile which apparently requires pairing in case of iOS, that said battey does seems to be able to be read and we were able to enable notification, in fact there is a new LTK:

bluetoothd[13467]: src/adapter.c:new_long_term_key_callback() hci0 new LTK for 88:64:40:6F:F8:35 type 2 enc_size 16

@Vudentz , Thanks for your reply, can we disable battery notification from bluez5.50 ? how to disable it ?

Path-A commented 3 years ago

Yes, this is a problem with the battery profile. This should be disabled by default. People have had success recompiling Bluez with the battery modules removed. Any word on fixing this issue?

Path-A commented 3 years ago

I was able to get this to work two different ways without recompiling:

The simplest way is to prevent the battery plugin from loading on boot by modifying your bluetooth service file with "bluetoothd -P battery". You can read more about it in the link above.

Hi Path-A, It works, thank a lot.
