Any other requirement for HEX on DFU in Android OS?

jimlin

image descriptionHi guys, I install V1.6 nRF ToolBox apk in my Android phone, and want to do the DFU operation. When the device in DFU status, I select the target HEX file but it shows me INVALID file so that the Android phone could not connect to the device. I found the 'ble_app_hrs.v7_1_0.hex' in the SDK folder should be OK with 'Init file selected' displayed. So, is there any other file needed exclude app hex? Or other setting ? The SD version is 7.0 and SDK is 6.0.

Thanks a lot.

    Could not access. I update to V1.12 from another market but found it was the same as before, HEX file invalid, like the attached picture. Bootloader and the application both based on SDK 6.0 with softdevice 7.0. No such appearence on the windows PC side with pca10001 dongle.
