Overview
---------------
{IDF_TARGET_NAME} has only one 2.4 GHz ISM band RF module, which is shared by Bluetooth (BT & BLE) and Wi-Fi, so Bluetooth can't receive or transmit data while Wi-Fi is receiving or transmitting data and vice versa. Under such circumstances, {IDF_TARGET_NAME} uses the time-division multiplexing method to receive and transmit packets.
ESP boards now support three modules: Bluetooth (BT & BLE), IEEE802.15.4, and Wi-Fi. Each type of board has only one 2.4 GHz ISM band RF module, shared by two or three modules. Consequently, a module cannot receive or transmit data while another module is engaged in data transmission or reception. In such scenarios, {IDF_TARGET_NAME} employs the time-division multiplexing method to manage the reception and transmission of packets.

Wi-Fi and BLE have their fixed time slice to use the RF. In the Wi-Fi time slice, Wi-Fi will send a higher priority request to the coexistence arbitration module. Similarly, BLE can enjoy higher priority at their own time slice. The duration of the coexistence period and the proportion of each time slice are divided into four categories according to the Wi-Fi status:
.. only:: SOC_IEEE802154_SUPPORTED
Currently, the only supported strategy ensures that the priority of BLE always takes precedence over IEEE802.15.4.

Dynamic Priority

The coexistence module assigns different priorities to different status of Wi-Fi and Bluetooth. And the priority for each status is dynamic. For example, in every N BLE Advertising events, there is always one event with high priority. If a high-priority BLE Advertising event occurs within the Wi-Fi time slice, the right to use the RF may be preempted by BLE.

Since the coexistence configuration option depends on the Bluetooth configuration option, please turn on the Bluetooth configuration option first before configuring the coexistence feature in the Wi-Fi configuration option.
As the coexistence configuration option relies on the presence of any two enabled modules, please ensure that both modules are activated before configuring any coexistence features.

Wi-Fi、BLE 二者对于 RF 的使用，主要是按照时间片来划分的。在 Wi-Fi 的时间片内，Wi-Fi 会向共存仲裁模块发出较高优先级的请求，在 Bluetooth 的时间片内，BLE 会具有较高优先级。共存周期大小和各个时间片占比根据 Wi-Fi 的状态分成四类：
