WiFiClient.cpp::setTimeout not working properly?

[cyberman54]

I'm trying to set a connection timeout before opening a wifi connection.
My code is:

const uint32_t RESPONSE_TIMEOUT = 30;
WiFiClientSecure client;
client.setTimeout(RESPONSE_TIMEOUT);
if (!client.connect(currentHost.c_str(), port)){
 ESP_LOGI(TAG, "Cannot connect to %s", currentHost.c_str());
 display(3, " E", "connection lost");
 goto failure;
 }

This openes the wifi connection successful, but it logs this error:
[E][WiFiClient.cpp:236] setSocketOption(): 1006 : 9

0x1006 is defined as
#define SO_RCVTIMEO 0x1006 /* receive timeout */

but what means error 9 ?

My fault: i set the client.setTimeout command at wrong place before opening the stream.
Closing this.

[cyberman54]

I was wrong, code placement seems not to be the error cause.
So reopening this.

As I understand it, the timeout is not used for the connection, but for reading and writing only. So you should use client.setTimeout() after client.connect().

I may have found the error code here, though: http://www.nongnu.org/lwip/2_0_x/group__infrastructure__errors.html

Beware, the timeout for WiFiClient (ie effectively what is called using WiFiClientSecure.setTimeout()) is not passed on to Stream, causing timeout errors while reading. See my comments at PR #1979.

Thanks for linking your RP #1979 , it explains exactly the problems in which i ran.
So again i close this issue, hoping that PR #1979 will be merged soon.

You're welcome :), you can use this PR by checking it out locally on your computer

Did that already. But my goal is not to keep a local update.cpp at all...

[Jeroen88]

Sure, that is why I want it to be merged soon too!

int connect(IPAddress ip, uint16_t port, int32_t timeout);
i think connection timeout is 3rd parameter .
