Samsung Android 10 DFU + BLE Connection issues.

[LASHCA@PIETERSE]

Hi, my development is based on the nrf52 SoC. I use the s132 Softdevice. 

One of my clients has recently experienced a Gatt error when uploading firmware using the nrf toolbox mobile app. Secondly, after uploading the firmware...the device disconnected from the nrf connect app after 30 seconds. This is a recurring issue, every time the device connects to the mobile app...it disconnects after 30 seconds.

Lastly, the important part of this post is that the client used a Samsung S10, Android version 10. I have tested the BLE connection and DFU update with various phones such as the Nexus, Pixel, Huawei and an Iphone and all of them work just fine. I have seen this type of issue replicate in China with region-locked smartphones. Im assuming this is an issue with the mobile devices BLE standard but could anyone please advise me as to how i can fix this issue as soon as possible. Thank you

Hiya,

Any update on this situation? I seem to be having the same issue when I am using the Nordic Device Manager with my NRF52840.
