  • I have an MDBT42q module. Trying to update the firmware before loading my code.

    I've made several attempts on iOS and Android versions to perform a DFU using the nRF Toolbox app (the only way I know how to update the firmware). I consistently get the following error.

    "Error: DFU Service not found"

    I've always updated my boards using this method. Any ideas? Here's a few things I've already tried.

    • Reset bluetooth
    • Tried different devices
    • Tried iOS and Android
    • Toggled on/off "external MCP DFU" in settings.
