nRF Toolbox couldn't do OTA using Bluetooth 5

Hi

We are using the nRF52840 and the application is OK now. Then I do the OTA using a Android phone which supports Bluetooth 5 and it's made in our country. I use the nRF Connect to connect the device and make it switch to the bootloader mode, at this time the device is advertising as DfuTarg. Then I use the DFU in the nRF Toolbox to connect it and then select the UPLOAD. But it indicates Uploading all the time then fail. Anyone could hele me have look? Thanks.

When the device is advertising as DfuTarg, I could use nRF Toolbox for IOS to do OTA. The nRF Toolbox for Android is download from github.com/.../Android-nRF-Toolbox

  • I don't think it's the issue with the nRFToolbox app. The app should work doesn't matter if it's Bluetooth 5 or not. It works on my Galaxy S8 which supports Bluetooth5.0

    It could be something else, please enable logging (RTT log) on the NRF52 and send the log to me. Also please find the log on Android when doing DFU.
