How to connect WiFi with certain channel?

[VladVons]

to speed up WiFi connection router should receive from ESP:
static IP, bssid, channel number

1) How to get from successful WiFi connection following data?
- channel number
- bssid

2) How to connect WiFi with certain channel number?
connect() has no such parameter

connect() has no such parameter

I don't believe this is possible on the ESP8266 -- the config structure that MicroPython passes to the underlying WiFi APIs has no way to specify the channel.

Edit: Actually this is possible. You could implement this quite easily in ports/esp8266/modnetwork.c:

Code: Select all

STATIC mp_obj_t esp_connect(size_t n_args, const mp_obj_t *pos_args, mp_map_t *kw_args) {

Add a channel kwarg, then you can add a call to wifi_set_channel(channel);

See https://github.com/esp8266/Arduino/blob ... A.cpp#L127 for a reference of how to use these APIs.
