Get RSSI when in AP Mode - Problem

[vonny232]

Hi,

I am working on firmware for the AI-Thinker ESP-06E variant.
I am using SDK 1.4.0 but with an older AT Command parser combined with the SDK so we could create some custom AT Commands.

Anyway, I have an unusual problem.

When we put the ESP module into AP Mode (using a webserver to send/receive testing and configuration details), the RSSI command wifi_station_get_rssi() does not work unless the module has successfully connected to a WIFI router at least once.

If I try and get the RSSI when in AP mode with a freshly programed ESP-06E, the function returns 31 (Error).

if I connect to a router in Station mode, then disconnect and get RSSI in AP mode, the function works OK.

I know this is complicated to describe, but it is a major problem for us because it means we cannot test the WIFI antenna Signal Strength during production test.

Any ideas?

Hi,

Can the "WiFi analyzer" help ? It can analyze the APs nearby.
