DFU Scanner Failed on Android O with SR3 v1.1

Ralph

Hi,

We are working on Android O with SR3  v1.1.

There is an issue that our Android STB can't find any BLE device using your library.

(https://github.com/NordicSemiconductor/Android-Scanner-Compat-Library)

Here is our code and error log


ScanSettings scanSettings = new ScanSettings.Builder()
               .setCallbackType(ScanSettings.CALLBACK_TYPE_ALL_MATCHES)
               .setScanMode(ScanSettings.SCAN_MODE_LOW_LATENCY)
               .setUseHardwareBatchingIfSupported(true)
               .build();
bleScanner.startScan(null, scanSettings, mScanCallback);

However We worked fine on Android N with SR3 v1.1.

    Hi Roshan,

    Thanks your help. I can find the DFU device now, but it gets another issue when DFU is running.

    Great that it helped. Could you please open a new issue for this? Opening a new issue would also help other users who might have faced the same issue! Thanks

    Hi Roshan,

    I tested DFU function on Android 8 smart phone with nRF connect :

    1.First, we try to use some combo keys to enter DFU mode but keep failing, in this stage we always bond the RCU with phone. 

    2.I found a config called NRF_DFU_BLE_REQUIRES_BONDS in sdk_config.h, so I clear it, just give it a try, and then it can enter DFU mode by combo keys without bonding.

    3.DFU can be done without bonding but connecting.

    Questions:

    1. What is the main difference between "connecting" and "bonding" ? 

    2. Why can't it enter DFU with NRF_DFU_BLE_REQUIRES_BONDS sets? No logs for this issue,it just reboot likes nothing happened.

    Thanks.
