Linux: WL1831 - Beacon loss and reconnect every hour

Other Parts Discussed in Thread: WL1831

Tool/software: Linux

So, I have a curious little problem which I'm not sure if it's related to WL1831 or not. It seems that every hour the wifi chip is experiencing beacon losses which disconnects the device from the current network and then reconnects it. We have not been able to relate it to any other device within the network (the minute changes between restarts). Has someone else experienced anything similar or have an idea of what could create such an issue?

See output from syslog below.

BR,

Måns

    Hello,

    How have you configured your wl18xx-conf.bin file?
    Did you use wlconf with the configure-device.sh script and selected wl1831 as your device?
    www.ti.com/.../swra489.pdf
    See section 2.

    You might have wrong configuration of the number of connected antennas etc. which can lead to issues like this one.

    Best Regards,
    Eyal

    Hi,

    Any update on this thread?
    Should we keep it open?

    I've been investigating your latest suggestion with the configuration of the device. We have configured it using the wlconf utility and as an input we've used the ini file provided by our module manufacturer MuRata. We have verified with them that we're using the latest version of that ini file (WL8_INI_1ANT_muRata_20130618.ini).

    The configuration file is not the easiest to read so I can't tell if everythings correct within it but from what I can see it's configured with two antennas, one 2.4GHz and one 5GHz. The WL1831 only supports 2.4GHz though so I'm guessing that could be our issue. Would it work to just change the following two rows or do I need to make other adjustments in the configuration file as well?

    NumberOfAssembledAnt2_4     	= 01 # Indicates the active bands and the number of mounted antennas for 2.4GHz;  
NumberOfAssembledAnt5       	= 01 # Indicates the active bands and the number of mounted antennas for 5GHz;

    Hi,

    In case you are using a wl1831 device you should actually put "0" for the number of "NumberOfAssembledAnt5".
    Is suggest you use wlconf and get a dump of your actual wl18xx-conf.bin file that was created using the supplied .ini file and make sure the values are indeed correct.

    ./wlconf -i /lib/firmware/ti-connectivity/wl18xx-conf.bin --get >dump.txt

    Best Regards,

    Thanks Eyal for your answer.

    We haven't tried your suggested change yet due to us waiting for a reply from our module manufacturer MuRata regarding their ini file. We're thinking we've got the wrong one from them and would like to clarify that first. If it's not the wrong one then it could possibly have other errors as well, thinking the number of antennans would be the easy thing to configure and they didn't get that right... We need to have that under control before continuing due to the possible problems it could cause us during our certification process.

    Please leave the conversation open for now and I'll get back with more details whenever I have some.
