ESP32 as wifi module in Legato 21.05.0

1

I have a ESP32 kernel module using SPI working from the command line on WP7702,

What do i have to change so the wifiService will work with ESP32 instead of a TI module ?

you might need to see the code in \legato-21.05.2.rc2\modules\WiFi\service

I got the src through leaf in VSCode
/home/pm/.leaf/wp76-legato_21.05.2.rc2-202302240920
I don’t see any changes in modules/wifi/service compared to the one currently used
/home/pm/.leaf/wp77-legato_21.05.0-202110290357

Would it be correct that wifi service is handled by scripts so if i make changes to tiwifi.sh and pa_wifi.sh or is there more to it?

I got it working!

root@swi-mdm9x28-wp:~# wifi client start
successfully called start.
root@swi-mdm9x28-wp:~# wifi client scan
starting scan.

Still need some more testing!
Is there a good example of using the dcs.api with both cell and wifi ?
