WIFI Signal strength is missing in wifi.radio Pico2w-Port -> implement wifi.radio.ap_info.rssi in Pico2w Port

[hubertmeier]

In circuitpython 10.x / libraries is it not possible, to ask the wifi signal strength, especially when wifi is connected.

print(dir(wifi.radio)) gives following result:

['class', 'addresses', 'addresses_ap', 'ap_active', 'connect', 'connected', 'dns', 'enabled', 'hostname', 'ipv4_address', 'ipv4_address_ap', 'ipv4_dns', 'ipv4_gateway', 'ipv4_gateway_ap', 'ipv4_subnet', 'ipv4_subnet_ap', 'mac_address', 'mac_address_ap', 'ping', 'power_management', 'set_ipv4_address', 'set_ipv4_address_ap', 'start_ap', 'start_dhcp', 'start_dhcp_ap', 'start_scanning_networks', 'start_station', 'stations_ap', 'stop_ap', 'stop_dhcp', 'stop_dhcp_ap', 'stop_scanning_networks', 'stop_station', 'tx_power']

Or am i wrong?

Thank you

.tx_power is the transmit signal strength, and can be read and written. Or are you talking about RSSI, received signal strength, from another host?

Scanning networks will yield the RSSI for each Access Point found.

While connected, wifi.radio.ap_info.rssi yields the RSSI of the connected Access Point. But it is currently implemented only for the espressif port, not for the raspberrypi port.

It is also possible (though a bit involved) to obtain RSSI for any active wifi device in the vicinity using https://docs.circuitpython.org/en/latest/shared-bindings/wifi/index.html#wifi.Monitor, but again this is currently implemented only for the espressif port, not for the raspberrypi port.

Thank you for the comments.

Yes, i talk about RSSI, the signal strength from the acces point. I want to see, how strong / good the connection to the acces point is. In my project are many pico2w's in many different networks and should report the quality of the connection, some are very good and some are a bit critical.

wifi.radio.ap_info.rssi would be my solution, so i hope, this would be implemented in the pico2-Port too. Disconnect the actuall Link, scanning new networks only for RSSI and connect new to the network is no option.

I need the picos because Hub75 work with these much faster (but not fast enough, this is another issue) than espressif, even matrixportal S3 is slower at refresh rates.

i updated the issue description.
