I have pico 4 wd kit, after a lot of troubleshooting I found onboard wifi module is not responding. I ordered ESP-01 module online but could provide instructions on how to bypass onboard wifi module and add this new chip into RDP ?

Which version of the pico-4wd product are you currently using? Suggest providing a picture of the product for us to see.
Your new ESP-01 module connects to RDP normally, go back and re-upload the code and see how it works.
You are currently using an older version of the product. The RDP expansion board is equipped with a Wi-Fi module, and if the Wi-Fi module is damaged, you will need to replace the entire RDP expansion board.
We recommend that you provide us with a picture of the RDP expansion board so we can confirm whether it is the older version.
