Your question

DFU doesn't work , I get errors:

[DFU] Device has disconnected , on Redmi 9C
[DFU] Connection failed (0x85): GATT ERROR,  on Samsung S20 FE

I notice when my phones are bonded to the nRF device the DFU is working.

DFU library 1.11.0 is working on Redmi 9C with or without bonding.

Hello, First of all, sorry for super late response. I was buried with other tasks.

DFU library 1.11.0 is working on Redmi 9C with or without bonding.

I wonder why. In Legacy DFU, unless you use forceScan flag, the bootloader is assumed to use the same MAC address then the app. In both logs above it seems like the reconnection to the bootlaoder succeeded, the correct Version number is read and only after sending the sizes the device disconnects.

Are you sending the same fw using 2.3.0 and 1.11.0? Could you share log from 1.11.0?

Rem193 commented 1 year ago

Hello, yes same FW.

I used the same FW and same phone Redmi 9C.

Are you sending the same fw using 2.3.0 and 1.11.0? Could you share log from 1.11.0?

Yes same fw, I bumped on my project the DFU library from 1.11.0 to 1.12.0 and it work well too

How I initialize the DfuServiceInitiator

// Kick off DFU
final DfuServiceInitiator starter = new DfuServiceInitiator(bleAddress)
    .setDeviceName(bluetoothManager.getAdapter().getRemoteDevice(bleAddress).getName())
                .setForceDfu(true)
                .setNumberOfRetries(DFU_NUMBER_OF_RETRIES)
                .setPacketsReceiptNotificationsEnabled(true)
                .setPacketsReceiptNotificationsValue(PACKETS_RECEIPT_NOTIFICATIONS_VALUE)
                .setKeepBond(keepBond);

Did you try disabling MTU request when using 2.3.0? It can be fine using DfuServiceInitiator. I'll go though the difference between those 2 tomorrow.

Rem193 commented 1 year ago

I disabled the MTU request with 2.3.0 but I got the same behavior.

DfuServiceInitiator

// Kick off DFU
final DfuServiceInitiator starter = new DfuServiceInitiator(bleAddress)
        .setDeviceName(bluetoothManager.getAdapter().getRemoteDevice(bleAddress).getName())
        .setForceDfu(true)
        .disableMtuRequest()
        .setNumberOfRetries(DFU_NUMBER_OF_RETRIES)
        .setPacketsReceiptNotificationsEnabled(true)
        .setPacketsReceiptNotificationsValue(PACKETS_RECEIPT_NOTIFICATIONS_VALUE)
        .setKeepBond(keepBond);

This, actually, indeed may be due to the remote not sending any packets while it erases the slot. Depending on Supervision Timeout in Connection Parameters the Central will disconnect if nothing is received. ST used to be very long, like 20 sec, not it's around 4-5 seconds, but may vary on different phones.

Have a look at the log I pasted before:

2023-10-04 09:42:21.344  I  Sending image size array to DFU Packet (0b, 0b, 57684b)
2023-10-04 09:42:21.781  D  onConnectionUpdated() - Device=EA:47:BA:46:6D:AB interval=18 latency=0 timeout=400 status=0
// disconnection after 4 seconds
2023-10-04 09:42:25.786  D  onClientConnectionState() - status=8 clientIf=8 device=EA:47:BA:46:6D:AB

The Supervision Timeout was set to 400, which translates to 4 seconds. And exactly after 4 seconds the connection is terminated.

If it is possible to modify the fw to request longer connection interval, that would help. Or, we can add a Connection Priority request from Android just before sending the sizes. Starting from Android 8+ Android requests 5 seconds Supervision Timeout, but seems like you need almost 7.

I wonder why 1.11 works...

philips77 commented 1 year ago

The logs from 1.11 you pasted above also have 4 seconds Supervision Timeout:

Perhaps it's not the Supervision Timeout, after all.

I tried on an other phone (samsung a15) with the latest version (2.5.0) of DFU lib but I still have an issue with the latest one and I notice that with an old version (2.1.0) the update works

I tested both versions on the same phone, same application I only changed the used version of the dfu library. I also tested with the latest nRF Device Firmware Update app from the play store, the FW update doesn't work too.

How I initialize the DfuServiceInitiator

        // Kick off DFU
        final DfuServiceInitiator starter = new DfuServiceInitiator(targetedBleAddress)
                .setDeviceName(bluetoothManager.getAdapter().getRemoteDevice(name)
                .setNumberOfRetries(DFU_NUMBER_OF_RETRIES)
                .setForceDfu(true)
                .setPacketsReceiptNotificationsEnabled(true)
                .setPacketsReceiptNotificationsValue(PACKETS_RECEIPT_NOTIFICATIONS_VALUE)
                .setKeepBond(keepBond);

Hi, I don't know how library version may cause a timeout in BLE communication. I'm about to release a new version (2.7.0), please give it a spin.
