APU1D with LTE Huawei ME909u-521

z3n0

1. Buried in the documentation for the modules is a note that you must provide 14 seconds of power to the module before you attempt to load drivers for it. So I added a 20 second delay to loader.conf.

how did you do?

now i have create this script:```
#!/bin/sh
usbconfig -u 1 reset

that reset the card but the pppoe is going up for 3-4 seconds and turn down..  :o

Change to loader.conf:

loader_delay="20"

If your ppp goes up and down you need to look at the log , check what stage its stopping at


clog -f /var/log/ppp.log

@conor:

Change to loader.conf:
loader_delay="20"
If your ppp goes up and down you need to look at the log , check what stage its stopping at
clog -f /var/log/ppp.log

I try with 40 sec and now work properly!!!
Thank you

ME909u-521 works for me out the box on pfSense 2.3.4 with an Alix 6f, I didnt assign the ue0 to anything, I just created a ppp0 entry for /dev/cuaU0.2 and I assigned ppp0 to OPT1, however like others I suffer the warm boot symptoms

@conor:

This gets it back HOWEVER it gets recognized as a new cuaUX port not the old one. I got around this by hacking devd.

Can you please tell me what you modified and which file /etc/pfSense-devd.conf?

I am now facing this problem, where the modem resets itself and attatches to different port straight away, so I end up with device not found /dev/cuaU0.0 and instead ls /dev gives me cuaU1.0

Thanks in advance

I modified:

/etc/devd.conf

**** WARNING you're not meant to change this file an upgrade will/may overwrite it. *********

Then I added the code at the bottom:

radios

attach 1000 {
match "vendor" "0x12d1";
match "product" "0x1573";
action "/usr/local/bin/php my own script T:ATTACH D:$device-name I:$inter
face P:$port A:$parent";
};
notify 1000 {
match "vendor" "0x12d1";
match "product" "0x1573";
match "type" "DETACH";
match "port" "[0-9]";
action "/usr/local/bin/php my own script T:DETACH D:$device-name I:$inter
face P:$port A:$parent";
};

So you'll need to write your own script (mine has a load of extra non related functionality) but the guideline of what you have to do is as follows:

On the ATTACH event you get a value for $device-name of something like: u3g0

You need to map that back to the correct cuaUX interface so I did this: (there may be a better or quicker way)

/sbin/sysctl -n dev.u3g.0.ttyname <== notice the location of the zero thats the last value of the $device-name u3g0

This gives you the value of the cua port e.g. I get:
U0

so my modem is on cuaU0.

Then create a symlink from /dev/cuaU0.0 ==> to /dev/radio.data

Don't format to map the serial port for diagnostics too:
Then create a symlink from /dev/cuaU0.0 ==> to /dev/radio.mgmt

Then you'll need to get the GUI file to allow you to select the radio.data interface.
/usr/local/www/interfaces_pps_edit.php <== **** WARNING you're not meant to change this file an upgrade will/may overwrite it. *********
change the line around line: 523 from:
$serialports = glob("/dev/cua[a-zA-Z][0-9]{,.[0-9],.[0-9][0-9],[0-9],[0-9].[0-9],[0-9].[0-9][0-9]}", GLOB_BRACE);

to:
$serialports = glob("/dev/radio.data", GLOB_BRACE);

I hope that helps.

As an aside I must think about a package for Huawei modems.

Huawei are ending the models:

Huawei ME909u-521
Huawei ME909u-523

Most suppliers will not be able to get them after the 31st December 2017, so if you're looking to deploy a few sites you'll need to look at another cellular modem.
