include esp8266 shield in Zephyr project

[mexco]

Dear, I need to upload data to w website using nRF5340DK. I decided to use NodeMCU V3, which has ESP8266. The related queires are:

1. How to include and use esp8266 shiled  in existing Zephyr project ?

2. How to include HTTP support and related library to upload dat using POST command ?

Dear Gulzar,

1. In your project's CMakeLists.txt, add this line: set(SHIELD esp_8266_arduino) .

The order of the lines is of importance. Your file will look something like this:

# SPDX-License-Identifier: Apache-2.0

cmake_minimum_required(VERSION 3.20.0)

set(SHIELD esp_8266_arduino)

find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(lvgl)

FILE(GLOB app_sources src/*.c)
target_sources(app PRIVATE ${app_sources})

More documentation for the ESP8266 shield.

Please see the note:

"Sometimes boards declare standard headers like Arduino R3 but not define all connections. Make sure that the board you are using have all definitions to avoid build errors."

I have not checked whether your board deviates from the standard.

In your project's prj.con you probably need to add the following configs. I have not yet tested this myself:

WIFI=y
NETWORKING=y

2. Are you planning to use AT commands to communicate with ESP8266?

Best regards,

Håkon
