RTOS/CC2640R2F: Custom board CC2640R2F

Part Number: CC2640R2F

Tool/software: TI-RTOS

Hello,

We have developed a custom board for CC2640R2F using RHB Package 32-Pin VQFN, changing GPIO woks fine. BLE advertise perfect, but when I trying to connect on Android device, the Application connection is losted.

Are there any changes to modify for different package?

    Hello Marcelo,

    Please see the "Configuring the RF Front-End for Custom Hardware" section in the BLE SW User Guide under "Running the SDK on Custom Boards". Most likely this is a misconfigured RF / antenna setting that is resulting in reduced RX sensitivity. We also discuss this topic in our pinned Getting Started / FAQ post here in the BLE forum under "Troubleshooting".

    Best wishes

    Hi Marcelo,

    This could also likely be caused by incorrect clock speed on the LF clock. What 32.768 kHz clock source are you using?

    Cheers,
