Requirements

Have you checked this problem on the example app?

Yes

FlutterBluePlus Version

1.29.6

Flutter Version

3.13.5

What OS?

Android

OS Version

13/14

Bluetooth Module

esp32c3

What is your problem?

If the device is not a paired device, connection, service discovery, etc. work very well but device is paired, my app cant discover services. Another problem, it's rare but it does happen, Sometimes it shows autoconnect true in logs but autoconnect true or just connect anywhere in the application. Im using only autoconnect(false).

"CONNECTION_TERMINATED_MIC_FAILURE"; // Connection terminated because Message Integrity Check failed on received packet.

chipweinberger commented 1 year ago

seems your device is really buggy

AdemYavuzCelik commented 1 year ago

It works fine in 1.5.2.

AdemYavuzCelik commented 1 year ago

This failure not happen on Xiaomi device, but it does on Google Pixel 6. Can we still say that the IoT device is buggy?

chipweinberger commented 1 year ago

from the logs it seems you're device might not like "requestMtu"

try setting mtu to null

i.e device.connect(mtu: null);

AdemYavuzCelik commented 1 year ago

We have to set mtu 512. i cant set null :/

AdemYavuzCelik commented 1 year ago

As per spec, error 61 (0x3d) means "CONNECTION TERMINATED DUE TO MIC FAILURE". The Message Integrity Check (MIC) is a 4-bytes extra field added to the BLE packet when encryption is enabled. That means the MIC failed on a packet received on your phone, which causes disconnection.

I found something like this, I wonder if anything has changed regarding this?
