Hello,
I wonder why. In Legacy DFU, unless you use Are you sending the same fw using 2.3.0 and 1.11.0? Could you share log from 1.11.0? |
|
Hello, yes same FW. I used the same FW and same phone Redmi 9C.
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);Logs DFU lib 2.3.0 DFU lib 1.12.0 |

Did you try disabling MTU request when using 2.3.0? |
|
I disabled the MTU request with 2.3.0 but I got the same behavior. DfuServiceInitiator Logs 2.3.0 |
|
Hmm.. I see that 1.11 spends almost 7 seconds erasing the secondary slot: but 2.3.0 gets a disconnection after just 4: |
|
Still have the issue with some mobiles with the latest app DFU 2.3.1
|

This, actually, indeed may be due to the remote not sending any packets while it erases the slot. Have a look at the log I pasted before: 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... |
|
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.
