Hey I am trying to run my mangoh as a gateway following this tutorial: > **[mangOH/mangOH](https://github.com/mangOH/mangOH/wiki/mangOH-Red-mt7697-WiFi)** > > mangOH-Red-mt7697-WiFi - I successfully updated the flash for the mt7697 as described. - I could not applied patches as they are not available for the current Legato version - I modified red.sdef to add the 3 samples app (wifiApTest, wifiWebAp, wifiClientTest) - Added the shell script mtwifi in /etc/init.d/ - Modified my network interfaces - Connected UART1 to the wifi module (at!mapuart=17,1) The interface is visible when i do ifconfig -a: > **network interface** > > # /etc/network/interfaces – configuration file for ifup(8), ifdown(8) > > # The loopback interface > > auto lo > iface lo inet loopback > > # Wired or wireless interfaces > > auto eth0 > iface eth0 inet dhcp > > # Wireless interfaces > > iface wlan1 inet manual > pre-up /etc/init.d/mtwifi start uart 1 > post-down /etc/init.d/mtwifi stop 1 However whenever I try to launch wifi, i get **Failed to start TI wifi, interface does not exist.** It looks like the mangOH look for this card that I don’t want to use. Do you know a way to avoid this ? Thanks ! My config: VScode extension MangOH RED - Release 13 - Legato 19.11.2 ---

Thanks for this document. I am working with the module WP77xx, so I can not use the .update present in this document. What should I update ? ---

Ok thanks, I will try that. Is it impossible to run this with Release 13 on WP77xx ? ---

I installed the Legato AF following this: [https://docs.legato.io/latest/basicBuildLegato.html](https://docs.legato.io/latest/basicBuildLegato.html) And with the tar files of the 18.03.0 version I did succeed to run make to compile this version. Then after cloning Legato\_patches an trying to apply the patch at my legatoAF, I get: `./apply_legato_patches.sh ~/legato_workspace/legato-18.03.0 18.03.0` fatal: not a git repository (or any of the parent directories): .git “18.03.0” doesn’t appear to be a valid release tag I’m stuck, can you help with that ? It would help me a lot if you could give me the right .update file ! ---

Ok to make it works I had to use apply\_legato\_patches\_untracked.sh as it seems they are some errors with the git tracking. Now as I try to compile the mangOH source code I have path issue with: #include “${LEGATO\_ROOT}/modules/WiFi/wifi.sinc” This directory does not exist in the legato version. I removed this link and add a full path to a similar one. **First question, do I have to change the mangOH source code version ? As it is not compatible with the old release ? (18.03.0 or 19.01.0)** ---

Where can you download the old mangoh source? ---

Ok for the record here is how I did: Follow [https://github.com/mangOH/mangOH/wiki/mangOH-Red-mt7697-WiFi](https://github.com/mangOH/mangOH/wiki/mangOH-Red-mt7697-WiFi) until the section _Patch Legato_ - Install the .spk from here [Release11\_WP77xx](https://source.sierrawireless.com/resources/airprime/software/wp77xx/wp77xx-firmware-release-11/#sthash.1XlR47iT.dpbs) - Create a leaf profile with _swi-wp77\_2.3.0_ SDK - Clone Legato patches from `https://github.com/mangOH/Legato_patches` - Apply patches to my LegatoAF: `./apply_legato_patches_untracked.sh $LEGATO_ROOT/leaf-data/$PROFILE_NAME/wp77-legato 19.01.0` - Clone the mangOH source code - Change the branch to v0.5.0 as the v0.6.0 include the wifi definition files from the LegatoAF (and they are not present here) - Uncomment line 15 of wifi.sdef > **wifi.sdef** > > //-------------------------------------------------------------------------------------------------- > // Sample system definition that includes essential services and WiFi-related services and sample > // applications. > // > // Copyright © Sierra Wireless Inc. > //-------------------------------------------------------------------------------------------------- > > #include “${LEGATO\_ROOT}/default.sdef” > > buildVars: > { > LEGATO\_WIFI\_ROOT={LEGATO\_ROOT}/modules/WiFi // File is selected by users, replace "ti" with "qca" to support qca chipset // For mangOH we select the PA script in the board file - i.e. red/yellow ...

Then I followed the indication in the document _How to test MTK wifi chipset on MangOH Red board_ (added mtwifi in /etc/init.d/ and chmod +x it, modifying interfaces to look like below, and setup the UART protocol as indicated). > **interfaces** > > # /etc/network/interfaces – configuration file for ifup(8), ifdown(8) > > # The loopback interface > > auto lo > iface lo inet loopback > > # Wired or wireless interfaces > > auto eth0 > iface eth0 inet dhcp > > # Wireless interfaces > > iface wlan1 inet manual > pre-up /etc/init.d/mtwifi start uart 1 > post-down /etc/init.d/mtwifi stop 1 Typing the commands below allows me start successfully the wifi uC and to observe wifi AP SSID on my mobile phone. > **Commands** > > wifi ap setssid “SIERRAWIFI123” > > wifi ap setdriver 1 > > wifi ap setmaxclients 1 > > wifi ap setsecurityproto 1 > > wifi ap setpassphrase “knockknock” > > wifi ap setdiscoverable 1 > > wifi ap start wlan1 I then added the wifiWebAp app to my module, starts it, everything run but I now **can’t see the SSID with my mobile phone** , I got those errors: > **Logs** > > ![Capture d’écran de 2020-12-15 12-50-14](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/4/4f845c0328b7ba2701c384e43256c644114d52af.png) Any ideas why I can’t connect ? ---

Did you see wlan0? Did you power cycle after these commands? ``` wifi ap setssid “SIERRAWIFI123” wifi ap setdriver 1 wifi ap setmaxclients 1 wifi ap setsecurityproto 1 wifi ap setpassphrase “knockknock” wifi ap setdiscoverable 1 wifi ap start wlan1 ``` ---

the error message is using wlan0 but now you don’t have this interface, probably this makes the problem. you need to fix that part. Did you really choose MediaTek in the webpage? ---

Ok got it working, My error was to use the app from: [https://github.com/legatoproject/legato-WiFi/tree/19.01-release](https://github.com/legatoproject/legato-WiFi/tree/19.01-release) Which is not up to date.
