MangOH RED 77 - Wifi Client config

philippesurbayrole · July 20, 2020, 4:06pm

Hello

I’m new on mangOH, and i try to connect my mangOH to a Wifi AP.
But when i try the connand “wifi client start”, i’ve this laconic message :
-> ERROR: le_wifiClient_Start returns ERROR.

cm info return:

Firmware Version:              SWI9X06Y_02.32.02.00 c2e98c jenkins 2019/08/30 07:28:21
Bootloader Version:            SWI9X06Y_02.32.02.00 c2e98c jenkins 2019/08/30 07:28:21

Legato version is:
20.04.0_ae298f9b1c63f46bf03abb990798e97a

I use the wifi client from legato git ( the version on mango git is deprecated !)

And the log from ‘wifi client start’ are

Please surround inline inline code or logs with single backticks like `this`. For multi-line code or logs, surround with triple backticks
```
like
this
```

This will ensure that the formatting of the text is preserved which will make it easier for others to understand your logs/code.

I have similar problem with my mangoh red wp76xx.
When i try the “wifi client start” command i get ERROR: le_wifiClient_Start returns ERROR.
On the uart console I have multiple errors:

It seems, that it is a common problem. Maybe there is a fix for that?

EDIT: I already tried applying Legato_patches , but it doesn’t support current (20.04) legato version.

jyijyi · August 4, 2020, 1:17pm

Are you using this iot card?

pawelkaniewski · August 4, 2020, 1:30pm

No, I am not using any IOT cards. I want to use built-in mediatek wifi module.

jyijyi · August 4, 2020, 1:34pm

Have you followed the guide here?

pawelkaniewski · August 4, 2020, 1:36pm

Yes, but I failed. I cannot apply Legato_patches because it doesn’t support current (20.04) legato version.

jyijyi · August 4, 2020, 1:40pm

Suggest you to try on R13 first

pawelkaniewski · August 4, 2020, 1:44pm

Do you mean SDK for WP76 (Release 13 + Legato 19.02.0) ?

I’m afraid it won’t run because legato_patches only support 19.01.0, and there is no stable, nor legit sdk release for 19.01.0

jyijyi · August 4, 2020, 1:52pm

How about FW R12 then?
I only tried on R9 before

Actually the only one stable version supported by Legato_patches is SDK for WP76 (Release 9 + Legato 18.03.0) Which is a bit old… I don’t won’t to use old sdk for my project. Are there any plans to release new version of Legato_patches? Or maybe there is a way to work around this problem?
