Question

Hello, I have a Bluenrg-ms connected to a STM32 for the Bluetooth connectivity. How can I set the Bluenrg to use either a 32MHz or 16MHz external crystall oscillator? Thank you very much

    Please use BlueNRG GUI, "menu | Tool | IFR/Device Configuration" to config accordingly.

    I too am trying to configure my board's IFR, but I am using the B-L475E-IOT01A (DISCOVERY), for which there is not an option in IFR/Device Configuration. Any idea how I can make this work?

    SPBTLE-RF module is based on BlueNRG-MS chip.

    Usually there is no need to modify IFR configurations for the Discovery kit.
