ESP8266 Wifi response timeout error

I have set up the ESP8266 wifi on a pico on UART0 so on the wifi chip I have power and gnd and uart0tx to GP17 and rx to GP16. Code included below.

ESP82666 wifi unit: U0TXD esp8266 wifi -> GP17 pico UART0 TX U0RXD esp8266 wifi -> GP16 pico UART0 RX

3.3 -> 3.3 CH_EN -> 3.3 gnd -> gnd

no additional wires, am I missing connections?

NOTE: I have tested originally on a hidden network I am not sure if this is an issue and if so will there be additional flags to set? NOTE: I have also tested on a regular network and the exact same result of response timeout error. NOTE: I have tested with a proper password and an invalid password and the same result of response timeout error.

The issue is it immediately gives a timeout after connecting (or what I think is connecting.

Is there something broke in the driver or is there something I am missing? Thanks in advance!
