Function esp_idf_bindgen::esp_wifi_set_max_tx_power

pub unsafe extern "C" fn esp_wifi_set_max_tx_power(power: i8) -> esp_err_t

@brief Set maximum transmitting power after WiFi start.

@attention 1. Maximum power before wifi startup is limited by PHY init data bin. @attention 2. The value set by this API will be mapped to the max_tx_power of the structure wifi_country_t variable. @attention 3. Mapping Table {Power, max_tx_power} = {{8, 2}, {20, 5}, {28, 7}, {34, 8}, {44, 11}, {52, 13}, {56, 14}, {60, 15}, {66, 16}, {72, 18}, {78, 20}}. @attention 4. Param power unit is 0.25dBm, range is [8, 78] corresponding to 2dBm - 20dBm. @attention 5. Relationship between set value and actual value. As follows: +------------+--------------+ | set value | actual value | +============+==============+ | [8, 19] | 8 | +------------+--------------+ | [20, 27] | 20 | +------------+--------------+ | [28, 33] | 28 | +------------+--------------+ | [34, 43] | 34 | +------------+--------------+ | [44, 51] | 44 | +------------+--------------+ | [52, 55] | 52 | +------------+--------------+ | [56, 59] | 56 | +------------+--------------+ | [60, 65] | 60 | +------------+--------------+ | [66, 71] | 66 | +------------+--------------+ | [72, 77] | 72 | +------------+--------------+ | 78 | 78 | +------------+--------------+ @param power Maximum WiFi transmitting power.

@return

• ESP_OK: succeed
• ESP_ERR_WIFI_NOT_INIT: WiFi is not initialized by esp_wifi_init
• ESP_ERR_WIFI_NOT_START: WiFi is not started by esp_wifi_start
• ESP_ERR_WIFI_ARG: invalid argument, e.g. parameter is out of range
