The foreground service creates BLEManager and connects to BLE devices with useAutoConnect(true). I have bound multiple Bluetooth devices and switched between them in the list. What I was doing wrong was in the discover services. My guess is that the "Ble library update": "BLE library updated to version 2.

The problem is, that in the current version all BLE requests are performed from the main thread, while the gatt callbacks use their own thread, What I meant was that it might have been nullified on disconnection (it's not, as uuid is logged) or not refreshed after the second service discovery (so it was obtained on the first connection), but I think even such should work, as all it's Did you take any sniffer logs, for example using hci-logs on Android? I agree that this is more a StackOverflow question, or at least for DevZone, if you are using Nordic chips. 2. . It works as expected on Android 11 and Android 12. hi~ Now I pair my mobile phone with the device and connect it with Bluetooth.

Latest version With our BLE lib, we connect to the GATT peripheral. The problem is that Android-BLE-Library needs to establish a connection at least 1 time before using the flag autoConnect internally, unfortunately, that's where the troubles begin because I'm looking to use the flag autoConnect precisely because I don't need to connect quickly and I want to save battery life.

I don't know if this is the direct cause, but sometimes BleManager's onServicesDiscovered is not called. I have an activity that starts a foreground service. So the library works next way: it stores request and depending of its type - performers different operations in our case NordicSemiconductor / Android-BLE-Library Public. From the documentation it's not quite cle as you can see [Server callback] Notification sent (status=0) is shown (from the Ble library) but somehow sendNotification finished nor sendNotification DON'T FINISH hasn't been shown and we are making a synchronous call so it should be reached.

In my case I need the RSSI Value to sort for highest signal first in a space where many of our devices are available. lang. 9. It would be great if the BLE library also reflects this change to enable apps to work without location permission when required. The connection worked just fine.

Hi, As shown in the title, i've an issue related to random connection timeouts that cause the user of our application to wait too long for a successful connection attempt, that hopefully happens after 10/20 seconds. Both Android devices are running my app (with your library) where one is acting as GATT service and the other as client. I read #3 for sending more than 20 bytes. This just adds a delay, which causes troubles when you write and get notifications from the same characteristic (data is reused for sending and receiving and may be overwritten). However, whether MTU is 23 (max 20 bytes), or 512 (max 509 bytes of payload), if your actual payload is longer than that you need to Hi, We are facing some issues between our ble devices (ble version 5) and android mobiles using nrfsdk ("Android-BLE-Library") library.
