gatt Error when searching for device when location is not active

[eshan-gr]

Where do you suspect the issue?

Issue in DFU library, e.g. upload stops in the middle

Version

2.8.0 (Latest)

Describe the issue

@philips77 Firstly sorry for tagging and pinging but we are on a time constraint and this issue is just unique.
Our BLE device is a custom device which transmits data in json for most of the commands and has a dedicated DFU mode. And it does not support bonding of any sort, When we try to bond we get a popup in phone but android system shows a toast that it cannot be proceeded without PIN or a passkey so we cannot bond the device. Here is the log when flashing the firmware

BUT strangely while in this process and if i Open the NRF Connect app and then try to manually connect the device which is named "DFU" in its dfu mode then what happens that nrf connect while connecting uses some location data as i can see the green location button usage in my notification bar (A13) and then i open my app from recents and firmware process starts.
I tried adding fine location and granting it but doesnt work, so what does NRF Connect app does with the location that too in above android 12.
My dfu config is this

 val incrementedMacAddress = incrementMacAddress(deviceAddress ?: return)
        Log.d(TAG, "startDFU: Incremented MAC :FROM: $deviceAddress :TO: $incrementedMacAddress")

        dfuServiceInitiator = DfuServiceInitiator(incrementedMacAddress)
            .setForeground(false)
            .setDisableNotification(true)
            .setDeviceName("DFU")
            .setForceDfu(false)
            .setRebootTime(30000L)
            .setScanTimeout(10000L)
            .setMtu(23)
            .disableMtuRequest()
            .setKeepBond(false)
            //.setNumberOfRetries(1)
            .setPrepareDataObjectDelay(300L)
            .setPacketsReceiptNotificationsEnabled(true)
            .setPacketsReceiptNotificationsValue(5)
            .setForceScanningForNewAddressInLegacyDfu(true)
            .setUnsafeExperimentalButtonlessServiceInSecureDfuEnabled(true)
            .setZip(zip.absolutePath)

i have tried experimenting with reboot times, experimental unsafe, mtu, disable mtu, etc

Hello,

As far as I understand, your issue is that your app cannot connect to a device unless you open nRF Connect.

One problem that I have with it, is the following log:

19:48:25.150 25469-25623 BluetoothGatt    D  onClientRegistered() - status=0 clientIf=6

!!!!!!!!!!!!!!!!!!!! I WENT TO NRF CONNECT AND CONNECTED MANUALLY WHILE MY APP FIRMWARE FRAGMENT WAS INITIATING DFU, AND THEN BELOW LOG APPEARED !!!!!!!!!!!!!!!

19:48:25.227 25469-25623 BluetoothGatt    D  onClientConnectionState() - status=0 clientIf=6 device=C0:6B:DE:F6:DC:1E

The time between these events is just 77ms, which is too low for opening nRF Connect and starting scanning.

Anyway, I see one possible reason. Are you scanning in your app before starting the DFU? Where do you get the BluetoothDevice object from? Could you ensure, that your device is in fact advertising which the library tries to connect (le't say with another phone running nRF Connect?
Also, are you able to repeat the DFU again (if the device doesn't change the MAC addresses) after one successful try?
It may be, that Android is "looking for" a public MAC address type for the connection, and if your device is advertising with a random address, the connection never gets initiated. When you start scanning with nRF Connect Android scans it, saves the MAC type (public/random) and as there's a new connection to "stored MAC" it knows its type, therefore the connection succeeds.

In short:

1. Does your device rotate MAC address?
2. Is it a random type MAC: static / private resolvable / private non-resolvalbe?
3. Are you scanning before starting DFU? Are you able to connect to the same device in your app before starting DFU?

[eshan-gr]

Thanks for pointing, although this log is slightly old version of the same problem, The device doesn't rotates any address never, It has a fixed mac where last char is incremented while in DFU, and our phones and any nordic app can discover it, Our firmware process is allowed to user after a connection, So we first connect to the one with local pairing mode using datastore

suspend fun scanForDeviceByMac(targetMacAddress: String): BluetoothDevice? {
        val autoCallback = object : ScanCallback() {
            override fun onScanResult(callbackType: Int, result: ScanResult?) {
                result?.device?.let { device ->
                    if (device.address.equals(targetMacAddress, ignoreCase = true)) {
                        stopAutoScanner(this)  // Stop scanning once we find the device
                        foundPairedDevice.complete(device)
                        Log.d(TAG, "Device found with MAC: $targetMacAddress")
                    }
                }
            }

            override fun onScanFailed(errorCode: Int) {
                Log.e(TAG, "Scan failed with error code: $errorCode")
                stopAutoScanner(this)
                foundPairedDevice.complete(null)
            }
        }

        try {
            scanner?.startScan(mutableListOf(deviceFilter), scanSettingsAndConditions, autoCallback)
            Log.d(TAG, "Scanning for device with MAC: $targetMacAddress")

            // Await for the scan to complete or timeout
            withTimeout(10000) { // Timeout after 10 seconds
                return@withTimeout foundPairedDevice.await()
            }
        } catch (t: Throwable) {
            Log.e(TAG, "Scan timed out or failed unexpectedly")
            logError(t)
            stopAutoScanner(autoCallback)
            return null
        } finally {
            stopAutoScanner(autoCallback) // Ensure we always stop scanning, even on exceptions
        }
        return foundPairedDevice.await()
    }

and pass it to the connection initializer to connectGatt and also whole logic happens succesfully , be it parsing battery or other data etc, and update button appears in a screen where if pressed then we close the scanner, callback and disconnect and then device enters dfu mode with a bright led for that mode and the dfu initiator starts in a next fragment.

I will attach a video and log after clearing some private logs and app screens.
