Yes, but you could remove the modem part and just use the AT command client as a starting point for your application. In the end for the AT client interface it doesn't matter if you talk to a modem or an ESP32.

Hi langestefann and thanks for your reply :)

I looked at the AT client but unfortunately it only forwards AT commands from an UART to the modem.
I also started to look at the HCI possibility but I don't think it works with Wifi and for now I only have one UART line between the nRF9160 and the ESP32. I also need to add custom commands so the at-slave if the best choice for now.

Thanks :)

Hi. I don't know of any AT command driver, but you could copy some of the work done by Nordic here: developer.nordicsemi.com/.../README.html

I have used the ESP AT firmware and found it extremely unstable and unreliable. However, this was a few years ago so maybe it has improved. Would it be an option to use HCI? https://docs.espressif.com/projects/esp-idf/en/v4.2.3/esp32/api-reference/bluetooth/controller_vhci.html And see: docs.zephyrproject.org/.../hci_drivers.html

I'm not sure if it supports wifi though.
