GATT Error (0x85) after upload beacon hex

[varon]

After I uploaded hex and dat file which is compiled from sample beacon source code in SDK to nRF51822 Beacon Kit via nRF master control panel app, I got Upload failed GATT ERROR 113 message and LED doesn't blink anymore.

After that,I try to connect device again but connect button in master control panel turn to gray color. And when I try to connect it again, it still got GATT error and cannot run DFU function. However, nRF beacon app still found it normally. but cannot DFU like master control panel.

What's happen? What's GATT 113 error and how to resolve it?

Hi Varon,

That appears to be a "BLE_GAP_SEC_STATUS_PAIRING_NOT_SUPP" error. I don't know how to solve it but perhaps that is a big enough clue to get you going.

@Varon: You have GATT Error 113 on Android side or on nRF51 side ?

Which DFU bootloader did you use ? The DFU bootloader that comes with nRFBeacon SDK won't need the .dat file, you can just choose not to use the .dat file when asked in the app.
