[FR] Enable WiFi standlone module is confused

[Johnny-Martin]

Is your feature request related to a problem? Please describe.

My board is Fysetc Spider 2.3, and I buy a wifi module(SPIDER-RRF-WIFI) for the board so that I can control by 3D printer with my laptop.

The Wifi module need a serial port, and the problem is, I don't know how to configrate these two serial ports to enable the WiFi module by reading the comment in the header file.

`/**

• Select the serial port on the board to use for communication with the host.
• This allows the connection of wireless adapters (for instance) to non-default port pins.
• Serial port -1 is the USB emulated serial port, if available.
• Note: The first serial port (-1 or 0) will always be used by the Arduino bootloader.
• :[-1, 0, 1, 2, 3, 4, 5, 6, 7] */

  define SERIAL_PORT 1

  ......... /**

• Select a secondary serial port on the board to use for communication with the host.
• Currently Ethernet (-2) is only supported on Teensy 4.1 boards.
• :[-2, -1, 0, 1, 2, 3, 4, 5, 6, 7] */

  define SERIAL_PORT_2 -1

  `

What value should I assign to these two serial ports? And how to turn on the wifi module?

Please help me, thanks a lot!

Describe the feature you want

I hope the user can understand every number means for the serial port by reading the comment in the header file.

You need to look at the pins for your controller.

Its plugged into exp1 and exp2 so it has to be a serial port on those connectors

PC6 and PC7 are UART 6

So it looks like you need serial port 6 enabled

reopening.. issue is not only serial port SPIDER-RRF-WIFI is running DuetWiFiSocketServer firmware code... that marlin doesn't know how to talk to

They are trying to run RRF-related firmware on that module. It needs to be flashed with something like ESP3D for it to work with Marlin, so it's not really a bug.

That is why its a feature request. To support the module as supllied

Thanks for reopening this issue, I had reverse engineering of SPIDER-RRF-WIFI module, and here is the schematic:

The EXP1 of this WiFi module is for UART communication, and the core module is ESP-WROOM-02D. https://www.espressif.com/sites/default/files/documentation/esp-wroom-02u_esp-wroom-02d_datasheet_en.pdf

I will try to flash this module with ESP3D firmware in few days.
