BLE/2.4 GHz Radio Coexistence

The CC3230x device is designed to support BLE/2.4 GHz radio coexistence. Because WLAN is inherently more tolerant to time-domain disturbances, the coexistence mechanism gives priority to the Bluetooth® low energy entity over the WLAN.

The following coexistence modes can be configured by the user:

  • Off mode or intrinsic mode

    • No BLE/2.4 GHz radio coexistence, or no synchronization between WLAN and Bluetooth® low energy—in case Bluetooth® low energy exists in this mode, collisions can randomly occur.

  • Time division multiplexing (TDM, single antenna)
    • In this mode, (see Figure 10-1) the two entities share the antenna through an RF switch using two GPIOs (one input and one output from the WLAN perspective).
  • Time division multiplexing (TDM, dual antenna)
    • in this mode, (see Figure 10-2) the two entities have separate antennas, No RF switch is required and only a single GPIO (on input from the WLAN persective).

Figure 10-1 shows the single antenna implementation of a complete Bluetooth® low energy and WLAN coexistence network. The Coex switch is controlled by a GPIO signal from the BLE device and a GPIO signal from the CC3230x device.

Figure 10-2 shows the dual antenna implementation of a complete Bluetooth low energy and WLAN coexistence network. Note in this implementation no Coex switch is required and only a single GPIO from the BLE device to the CC3230x device is required.
