esp32,esp8266: Add support for the Espressif ESP-NOW protocol. ESP-NOW is a proprietary wireless communication protocol which supports connectionless communication between ESP32 and ESP8266 devices, using vendor specific WiFi frames. This commit adds support for this protocol through a new `espnow` module. This commit builds on original work done by @nickzoic, @shawwwn and with contributions from @zoland. Features include: - Use of (extended) ring buffers in py/ringbuf.[ch] for robust IO. - Signal strength (RSSI) monitoring. - Core support in `_espnow` C module, extended by `espnow.py` module. - Asyncio support via `aioespnow.py` module (separate to this commit). - Docs provided at `docs/library/espnow.rst`. Methods available in espnow.ESPNow class are: - active(True/False) - config(): set rx buffer size, read timeout and tx rate - recv()/irecv()/recvinto() to read incoming messages from peers - send() to send messages to peer devices - any() to test if a message is ready to read - irq() to set callback for received messages - stats() returns transfer stats: (tx_pkts, tx_pkt_responses, tx_failures, rx_pkts, lost_rx_pkts) - add_peer(mac, ...) registers a peer before sending messages - get_peer(mac) returns peer info: (mac, lmk, channel, ifidx, encrypt) - mod_peer(mac, ...) changes peer info parameters - get_peers() returns all peer info tuples - peers_table supports RSSI signal monitoring for received messages: {peer1: [rssi, time_ms], peer2: [rssi, time_ms], ...} ESP8266 is a pared down version of the ESP32 ESPNow support due to code size restrictions and differences in the low-level API. See docs for details. Also included is a test suite in tests/multi_espnow. This tests basic espnow data transfer, multiple transfers, various message sizes, encrypted messages (pmk and lmk), and asyncio support. Initial work is from https://github.com/micropython/micropython/pull/4115. Initial import of code is from: https://github.com/nickzoic/micropython/tree/espnow-4115.
