Yes I know, is the SDK released or open source, obviously a bug somewhere

Would like to have a look

No it's closed source. You'll need to raise this with espressif on their site: http://bbs.espressif.com/.

This code nearly works for me.....

If theres only one station connected then stat_info comes back as null...

If theres more than one it comes back with the info, any ideas ?

I suspect that "wifi_softap_get_station_info" is updated a short time after "wifi_softap_get_station_num".

So that if you call "wifi_softap_get_station_info" immediately after "wifi_softap_get_station_num", you don't get the correct results because whatever internal connection table hasn't been updated yet.

Perhaps "wifi_softap_get_station_num" is updated immediately after connection, but "wifi_softap_get_station_info" isn't updated until after the IP address, subnet mask, etc. is sent to the client a fraction of a second or so later.

I added a 1 second delay between the call to "wifi_softap_get_station_num" and "wifi_softap_get_station_info" and I get the correct results. I know it's kind of hackish, but maybe someone has a more elegant solution.

I think your are quite correct, I have checked this and yes it happens later on.

Totally useless for me as I am dealing with streaming data coming and and need to handle that before the tiny buffer overflows..

Will raise it as a bug when I have time

Thanks

WiFi.softAPgetStationNum() returns the number of connected stations/clients to SoftAP.
