MasterControlPanel cant find device

[Arthur]

Hi !

I'm trying to run the BLE bootloader example (here). I succesfully programmed the SoftDevice and the DFU bootloader :

The device start in bootloader mode (LED 1 and 3 ON). Then I connect my computer to the device DfuTarg (LED 1 go OFF and LED 2 ON). But the MasterControlPanel can’t find anything.

MasterControlPanel v3.10.0.14 nRFgo Studio v1.21.1

You say that you connect your computer to the DfuTarg. Do you mean that you are using the bluetooth hardware of your computer to connect? You need to connect using the Master Control Panel, and the Master Control Panel only works with nRF51 chips. So you need an extra nRF51 dongle or DK, then flash the master emulator firmware to the dongle or DK, then you can connect to the other DfuTarg device using MCP. If you don't have an extra dongle or DK you can use the Master Control Panel for Android or iOS. Download it from Google Play or App Store. The Android/iOS version also supports DFU.

Yes was using my computer bluetooth's. I tried to flash a second board with the master emulator firmware using MCP as you say. But it's not compatible for nRF52 devices.

As a temporary solution, do you think it's possible to use the MCP for Android in the emulator of Android Studio ?

Ja, sorry for not being clear. It's only for nRF51. Not sure if it will work with Android emulator. No one of us have tested that before. I guess you just have to try.

Well, I will give the emulator a try.

It seems there are no android emulator that support Bluetooth. However virtualisation may work (I didn't try).
