No connection between esp8266 and FC

Hi, does anyone have an idea why I have no connection between esp and FC? The menu in mission planner is not available. I can connect to the module’s WiFi network using smartphone and the module has software loaded in accordance with the Ardupilot instructions.

my hardware:
speedybee F4 v3
Adafruit esp8266

conections:
module RX to FC TX1
module TX to FC RX1



From ESP8266 wifi telemetry — Copter documentation:

If you have problems connecting, it may help to set BRD_SER1_RTSCTS = 0 to disable flow control although this is not normally necessary

How is your BRD_SER1_RTSCTS parameter looking?

The menu is only necessary if you want to use it in client mode, which you aren’t at the moment.

Apart from that everything else the connections and configuration look good to me…

there are very similar parameters in mission planner but this exact one does not exist
