RP2040 not sending wifi when in station mode #47

Hi,

Thank you for this very nice library.

I wanted to connect to an OSC server (desktop computer with Python OSC server) through Wifi with a Raspberry Pi Pico (being the client).

I copied some parts of your example https://github.com/hideakitai/ArduinoOSC/blob/main/examples/arduino/OscWiFi/OscWiFi.ino but kept getting "wifi is not connected" messages in the log.

I modified lines 71, 90, and 102 of ArduinoOSCCommon.h as follows

if ((WiFi.status() == WL_CONNECTED) || (WiFi.getMode() == WIFI_STA)) {

instead of 

if ((WiFi.status() == WL_CONNECTED) || (WiFi.getMode() != WIFI_STA)) {

and now it works.

I'm not really sure why mode should not be WIFI_STA at all times, especially when line 56 of the example sets it to WIFI_STA ?

Thank you for your help, All the best

Maybe your library version is old. The latest release is fixed, as you suggested.

https://github.com/hideakitai/ArduinoOSC/blob/97082882a0cb8e774ba152a6cc5087704cdc244e/ArduinoOSC/ArduinoOSCCommon.h#L71

WiFi.status() == WL_CONNECTED is for Station Mode. It checks if the board is connected to the WiFi AP. WiFi.getMode() != WIFI_STA is for AP Mode.

Ah, sorry you modified from WiFi.getMode() != WIFI_STA to WiFi.getMode() == WIFI_STA ? I think your board is not correctly connected to WiFi AP (WiFi.status() == WL_CONNECTED is false) or the bug of WiFi library of Pi Pico

Hi,

Thank you for your response :)

I'm not sure to understand: the mode should not be station after connection is successful ? I don't want the Pico to be an Access Point, I want it to connect to an already existing Wifi network

Anyways, I have switched the project to C/C++ SDK and use this library https://github.com/madskjeldgaard/PicoOSC

All the best !

No. The meaning of this if statement is:

So, if you use station mode, it checks if the board is connected to an existing AP. But it doesn't care if you use AP mode.

I'll confirm with Pi Pico W later :)
