How to get wlan0 interface with ESP8266 module?

[jayaprasad]

Hi,

I'm working on Spresense with an ESP-01 module (with ESP8266) connected to UART2. Even when I've enabled symbols for wireless, I'm unable to get the wlan0 interface up with the NuttX SDK.

I've connected my module as described in this page -

https://developer.sony.com/develop/spresense/tutorials-sample-projects/spresense-tutorials/how-to-equip-spresense-with-wifi-connectivity

How can I get the wlan0 iface functional?

What all config symbols to enable for this?

Can I use the wapi utility to configure wlan0 for ESP8266 module?

Can anyone please point me to a driver available or sample code based on NuttX SDK?

Please see my connection diagram below

Hello @jayaprasad,

I'm sorry for the slow response. I found a previous post in the forum regarding this module in the SDK that you might find interesting:
https://forum.developer.sony.com/topic/104/how-to-bring-up-the-network-in-spresense?_=1623396622282

I also found an implementation that uses the ESP8266 in an SDK app - I actually think it is the same one that is mentioned in that other thread. if you send me a private message with your email address, then I will share the source code it to you.
