Hi, how can I get mangOH yellow builtin wifi to work? When wifiService is running and I “wifi client start”, it responds me with this: ERROR: le_wifiClient_Start returns ERROR. When I set all the necessary settings and try “wifi ap start”, i get back: ERROR:le_wifiAp_Start returns -1.
Thanks in advance

Hi Elmo,
What exactly did you do before your have started the wifi service and client? Did you do some system changes? Like installing a new Mangoh Build? Or using the swiflash command?
We also had some problems with Yellow Wifi last week after installing the Mangoh Build without Octave. Here is the ticket:
Due to time constrainst we ended up implementing the POC with FX30 and IOT wifi card but would be good to clear this issue.
Please share us the log messages (logread cmd) when you start the wifi client. If you have the same problem you should see an error message like “‘/legato/systems/current/modules/brcmfmac.ko’: File exists”” .
Best,
tom
Thanks for the answer, here is my logread of wifi client start command:

Seems like it’s not the same problem as you had. I might have messed up this unit trying to fix the problem, but i managed to test wifi with a brand new yellow also. Same errors there.
-Elmo
Yes it seems to be a different problem. I don’t know what changes you have made before It seems to be that it is trying to enable the TI wifi which can be found for example on the IOT card. I presume you are not using a wifi IOT card as Mangoh Yellow should have a fully working on-board Cypress wifi chip, so it is not your goal. Could you install the offical Mangoh Yellow spk (https://mangoh.io/mangoh-yellow-resources-software) and see if it starts the right wifi script.
(BTW. Have you not changed something in the /etc/network/interfaces or some other files ? I think the Cypress wifi should be connected to wlan1 and TI chip to wlan0 but I am not sure)
Did you update your firmware or is it standard yellow software? If yellow, I dont understand why you see mangohred on your log messages.
Thanks a lot, I will try to install yellow spk. I’m still afraid it won’t fix the problem as this has been the problem from the beginning. I haven’t touched interfaces as far as I remember. If I install yellow spk, will the interface file reset?
-Elmo
With this unit, I have updated the firmware. But when I first got this, I tried right away ”ifup wlan0” and I remember wondering why it said ”mangOH red board”. I thought it used some same drivers or something for the wifi. I will test another unit with the firmware it came with when I have time, but the wifi has not been working on that one either.
-Elmo
There is no reason to see mangoh red in log file.
Anyways, we will have a new spk and leaf packages available by tomorrow that should allow wifi to work with published commands
Hi, thanks for advices. i got it working by installing spk-file tom suggested. Everything’s fine now. Still when you try ”ifup wlan0” you get back some mangOH red-stuff, idk why is that.
-Elmo
ifup and ifdown use the /etc/network/interfaces file. There is some junk in that file pertaining to the TI WiFi IoT card. Please use ifconfig or use the wifi command provided by legato.
We have the spk available with the fix. Please try it and let us know.
Works like a charm. Thanks for the help.
