BK7231N Smartsocket does not connect to Wifi #555

Open btmerz opened 1 year ago

btmerz commented 1 year ago

Hello, I finally managed to get OpenBK installen on my BK7231N smart socket. I was also able to get the module configered, so that Relay, LED, pbutton and power measuring work. But unfortunately I'm not able to get the device connected to my WIFI. SSID (FRITZ!BOX 7490) is set correct and I also checked my wifi password several times. But It doesn't show up in the router and the WIFI LED is constantly blinking. When ich restart it in save mode I can connect to it in AP mode without problem. But i need it in my network for MQTT communication. Do you have any advice?

Thanks for the great project!

Would it be possible to see UART log from the device?

Are you able to compile the minimal WiFi connect example from our N SDK and see if it also fails to connect?

btmerz commented 1 year ago

Sorry, but I'm new to this project. How do I get this log? And is there a tutorial, how to compile this minimal version? Thanks for your help...

openshwprojects commented 1 year ago

Log is available at the TX2 pin of your BK device. You should connect UART directly to get that, so it might be problematic.

Regarding minimal build... well, I can see how that can be problematic. I would need to copy T SDK project example to N SDK for you. I might look into that later.

Anyway, is it your only Beken device? Are you able to tell us whether it is a problem specific to your device or specific to your WiFi? Does it connects to other WiFi AP well? That would help nail down the issue.

Hello, any chance that your Wifi password contains special characters? I am also using a Fritzbox 7490 which can create two SSIDs (one for guests). For testing, I set a very simple wifi password on the guest SSID to which the BL602 with the current firmware can connect just fine. When switching over to my main SSID with a more complex password, the module (BL602) does not connect and gives a Wlan802.11 status code = 53 (Invalid shared key (pairwise master key identifier or PMKID)). I set the Wifi password via MQTT, web requests & webUI console multiple times and am 100% sure that it is correct. Interestingly, the password shown in the logs is correct, as well. It does, however, show Mac 00:00:00:00:00:00. Is that correct? Thank you

I have tested it with my guest wifi with simple ssid and password with no success... currently  I have no time to connect a uart. Will try to test that later. I have only one device to test.Thanks for your support Gesendet von Outlook für AndroidVon: sebastianheierhoff @.>Gesendet: Freitag, 17.

Same here with a Fritzbox 7560. Wifi connection cannot be established. See also serial log below. I can exclude the wifi password characters. I use the same wifi password on a cheap china wifi repeater. The BL602 with this flashed firmware connects here w/o problems. With the original firmware from ewe the device connected to the Fritzbox, so it is a firmware issue that can be solved.

Does it connect to your Fritzbox if you change the PSK to something "easy", i.e. without special characters? Mine works fine if I change my key to "test" but doesn't if I use a longer key with special characters. Thus my assumption that it has something to do with the Fritzbox and its behavior when using complex keys.
