i’m trying to connect both WIFI and SPI

But i’m confused about the pinout i guess

In Espressif documentation it explains it uses UART1 to send AT commands to the built-in WIFI controller. They provide the pinout for various boards https://docs.espressif.com/projects/esp-at/en/latest/esp32/Get_Started/Hardware_connection.html

The nodeMCU ESP8266 V3 board seems to be quite popular. It uses an ESP-12E with it’s own documented pinout. https://components101.com/sites/default/files/2021-09/ESP12E-Datasheet.pdf

But for the NodeMCU ESP8266 V3, i can’t find a specification of using this UART1 for sending commands to WIFI.

The NodeMCU ESP8266 V3 ‘wemos’ variant (which i have) is not as popular and doesn’t have the ESP-12E board integrated; https://makerselectronics.com/product/wemos-nodemcu-v3-esp8266-340g-wifi-module-with-extra-memory-32m-flash

On the ‘wemos’ variant i’m using

• GPIO14/D5 pin as SPI clock
• GPIO13/D7 pin as SPI MOSI

But i can’t find info talking about how WIFI is accessed on the chip. E.g. This documentation (riddles with commercials) doesn’t even mention UART1 ? https://microcontrollerslab.com/esp8266-pinout-reference-gpio-pins/

So what i’m wondering about;

1. Since i’m having trouble with the WIFI AccessPoint not being visible when using SPI, but visible when i disable the part using the SPI interface; Is the WIFI AP so time critical that i can’t do much other stuff, or am i interfering with the WIFI module because i’m using SPI?

2. Also, i can’t find any code in github which does the actual AT commands when enabling WIFI by libary calls. I’d found user_interface.h where it declares e.g. wifi_set_opmode() but the only implementation i find is in a test folder(which doesn’t even seem to store a value). I’d also appreciate any info on how these methods are implemented to interface with the actual WIFI module.
