Thanks Ashish, I realize now that the level shifter in the schematic is not turned on by default, so there wouldn’t be intersection with the Wifi module. However, if someone wanted to use the wifi/BLE module and UART this level shifter would be on and the UART signal would then funnel to the Wifi module? Or is this Wifi UART only used to download firmware to the Wifi module if it’s in a bad state?
Also, was my above listed AT command correct to get the IOT UART online? Do you guys have any sample code that shows reading and writing over the UART? I see the LE_TTY api on legato, but I’m still not clear on how I would communicate with my external device and receive its feedback. http://legato.io/legato-docs/latest/c_tty.html
