/**
* @brief Get the version of ESPNOW
* @brief Get the version of ESPNOW. Currently, ESPNOW supports two versions: v1.0 and v2.0.
*
* The v2.0 devices are capable of receiving packets from both v2.0 and v1.0 devices. In contrast, v1.0 devices can only receive packets from other v1.0 devices.
* However, v1.0 devices can receive v2.0 packets if the packet length is less than or equal to ESP_NOW_MAX_IE_DATA_LEN.
* For packets exceeding this length, the v1.0 devices will either truncate the data to the first ESP_NOW_MAX_IE_DATA_LEN bytes or discard the packet entirely.
* For detailed behavior, please refer to the documentation corresponding to the specific IDF version.
