CC2340R5 3 wired PTA coex function

CC2340R5: How to Enable PTA Coexistence on CC2340R5?

Tool/software:

Hi TI expert,

 One E2E, "https://e2e.ti.com/support/wireless-connectivity/bluetooth-group/bluetooth/f/bluetooth-forum/1175345/cc2340r5-3-wired-pta-coex-function" mentions about 3 wire PTA coexistence with WiFi. But I can't find any document or F3 SDK user guide talking how to enable it and what are the 3 GPIOs for PTA setting. Could TI help on this?

Sincerely, Jesse.

    Hi !

    Our drivers in the F3 SDK do not implement 3 wire PTA coexistence. The F2 SDK used to support this feature, this documentation (link) can help the customer find a way to write their own driver for this feature. The customer's implementation can either be done at the radio layer, or can more simply be done in the application layer using event callbacks (see Peripheral_AdvEventHandler in the basic_ble example) and then read the status of the 3 wires to determine what to do.

    Kind regards,
    Maxence
