Connecting Esp32 to pico

[espruino-discuss]

Hi All,

I am trying to connect "ESP32 WeMos Lolin32" to the Espruino Pico through SPI2, since I have already used SPI1 pins for other things. this is the code I have written:

SPI2.setup({mosi:B15, miso:B14, sck: B13});
var esp32 = require("ESP32").connect(SPI2);

I'm getting the following error at 2nd line:

warning: module "esp32" not found uncaught error: sd card must be setup with e.connectsdcard first at line 4 col 28 var esp32 = require("esp32").connect(spi2);

.
Please help me resolve this issue. I'm using esp32 to use the bluetooth, any help on using the bluetooth will also be useful.

Thank You,

Hi,

I'm afraid there's no library for SPI communication with ESP32 built in to Espruino, so the code require("esp32") won't work.

But, you could still use the SPI2.setup({mosi:B15, miso:B14, sck: B13}); code and then manually send commands with SPI2.send/write - assuming the ESP32 has firmware installed that supports communication via SPI?

I'm not 100% sure if there is such a firmware... The standard AT command firmware (https://www.espressif.com/en/products/sdks/esp-at/overview) would appear to just want to communicate over serial...
