* @attention 1. This API should be called after esp_wifi_start() and before esp_wifi_stop()
* @attention 2. When device is in STA mode, this API should not be called when STA is scanning or connecting to an external AP
* @attention 3. When device is in softAP mode, this API should not be called when softAP has connected to external STAs
* @attention 4. When device is in STA+softAP mode, this API should not be called when in the scenarios described above
* @attention 5. The channel info set by this API will not be stored in NVS. So If you want to remember the channel used before wifi stop,
* you need to call this API again after wifi start, or you can call `esp_wifi_set_config()` to store the channel info in NVS.

* @attention 6. When operating in 5 GHz band, the second channel is automatically determined by the primary channel according to the 802.11 standard.
* Any manually configured second channel will be ignored.

* @param primary for HT20, primary is the channel number, for HT40, primary is the primary channel
* @param second for HT20, second is ignored, for HT40, second is the second channel
