How Activate wifi AP on mangOH red

Laurent · August 14, 2018, 9:22am

Hello,

I use a MangOH Red with WP7702.
I want to activate the AP wifi using the wifiwebAP interface.
But that does not work. When I click on “start”, nothing happens.

Is there a tutorial to explain how to activate the AP?

Best regards

I test now with a wp8548.
I did what indicated in the topic https://github.com/mangOH/mangOH/wiki/mangOH-Red-mt7697-wifi

But when I do ifup wlan1 I have the error :
insmod: can’t insert ‘/legato/systems/current/modules/mt7697wifi_core.ko’: No such file or directory

You need to wait for WP8548 release 16 which will be available soon

HI,

Now the wifiwebAP work on WP7702.
I can activate an AP. I can see the AP on my laptop

Now I want activate the AP in a consol on mangHO.
I enter this instructions:

wifi ap setssid “GARGAMEL”
wifi ap setmaxclients 5
wifi ap setsecurityproto 1
wifi ap setpassphrase “my_pass”
wifi ap setdiscoverable 1
wifi ap setchannel 1
wifi ap start wlan1
ifconfig wlan1 192.168.20.1 netmask 255.255.255.0 up

The ifconfig return ;

wlan1 Link encap:Ethernet HWaddr 00:0C:43:76:87:22
inet addr:192.168.20.1 Bcast:192.168.20.255 Mask:255.255.255.0

RX bytes:0 (0.0 B) TX bytes:76707 (74.9 KiB)

BUT I don’t see the “GARGAMEL” AP on my laptop.

Hi,
I found the right sequence to activate the AP in a consol:

wifi ap setssid GARGAMEL
wifi ap setdriver 1
wifi ap setmaxclients 5
wifi ap setsecurityproto 1
wifi ap setpassphrase my_pass
wifi ap setdiscoverable 1
wifi ap setchannel 1
wifi ap start wlan1
ifconfig wlan1 192.168.20.1 netmask 255.255.255.0 up
/etc/init.d/dnsmasq start

with in the dnsmasq.wlan.conf file: dhcp-range=wlan1,192.168.20.10,192.168.20.100,24h

Now I want activate the AP when I turn ON the manghoRed.
Test n°1 : I add the command in the init.d/data-init file, but it does not work.

Test N°2 : I create an app (command called by “RunSystemCommand” in the C file). When I start the app by the command “app start my_app” , it does not work. I can see " RunSystemCommand() 36 | Error wifi ap setssid GARGAMEL Failed: (32512)" with logread. If I start the application from the directory “/legato/apps/…/read_only/bin”, It work !!

Would you have the solution to activate the AP ?

Hi,

Do not use “wifi” command line tool from your app.
Instead use Legato WiFi APIs:
https://docs.legato.io/latest/c_le_wifi_ap.html

It seems that your application is based on the “old” version of WiFi AP test application.
For mangOH Red WiFi chip (MT7697), you have applied some patches as explained in the wiki page.
After applying the patches, the WiFi AP test application is modified:

le_wifiAp_Start()
is replaced by:
le_wifiAp_StartInterface(TEST_INTERFACE_STR)
le_wifiAp_SetIpRange(HOST_IP, IP_RANGE_START, IP_RANGE_END))
is replaced by:
le_wifiAp_SetIpRange(HOST_IP, IP_RANGE_START, IP_RANGE_END, TEST_INTERFACE_STR))

Could you try to modify your own app (llb.c) with this new TEST_INTERFACE_STR parameter?

Hi,

I installed the release 16 on the WP8548, but i have allways the error insmod: can’t insert ‘/legato/systems/current/modules/mt7697wifi_core.ko’: No such file or directory

For information, I followed the instructions of the Geting Started Guide to Install Mangho Distribution on the WP85. But at the end, when I use the “app status” command, I don’t see the redSensorToCloud application.
