Question: Raspberrry Pi PicoW

[hasenradball]

Dear Markus,

I would like to use the websocket from your lib to run on the PicoW with the official c sdk.
I just want to send a json object between server an client.

Is it easily possible to adapt or the grap the necessary code parts from your lib?

I actually have a working example with HTTP get via fetch but websocket is much more robust.

Theoretically possible but the lib uses some functions provided by the Arduino core like delay and so on.

you can implement the network stack of the C SDK via WebSocketsNetworkClient.

how hard this is hard to say since I never used the SDK directly.

any reason not to use the Arduino Core for the PicoW?
the ws lib directly supports this, and you still can access the SDK functions.

arduinoWebSockets/src/WebSockets.h

Lines 254 to 261 in 175e80f

	#elif (WEBSOCKETS_NETWORK_TYPE == NETWORK_RP2040)
	#include <WiFi.h>
	#include <WiFiClientSecure.h>
	#define SSL_BARESSL
	#define WEBSOCKETS_NETWORK_CLASS WiFiClient
	#define WEBSOCKETS_NETWORK_SSL_CLASS WiFiClientSecure
	#define WEBSOCKETS_NETWORK_SERVER_CLASS WiFiServer

Hi @Links2004,

thanks for the response.
Yeah for the Pico W I Iearned to love building the code with the C SDK and CMAKE, it is great and not so much overheat with the Arduino Framework.
The build time is faster with the C SDK too .

I have an working code with HTTP GET and want to upgrade to websocket.

So I tried the websocket on Arduino, it works for me, but I want to get it runing on the pure C SDK.
:-)

By the way...
do you know how to switch off the debug in arduino?
