Hello guys,

I bought 2 weeks ago a Topex Bytton gprs router on ebay. This bytton is actually a ASUS WL-500g Deluxe with a gprs modem attached. I took some pictures of it and it's insides. Their on my box at http://testsensor.snort.ro/bytton . I got the latest backfire on it, everything is working fine except the gprs modem which I've been trying to figure-out for 2 weeks now and it's driving me mad. In the pictures I took you can see the modem chip and it's model, it a Voxson EN2002. I haven't been able to find anything online about it. Is there something I can do to make it work?

Cheers!

I think, the most essential part of the package is the software and it's configuration. Flashing it with backfire before examining the previous configuration doesn't seem to be a good idea to me.

The original firmware had all modules built in the kernel... I had no way of finding out anything. Of course I've saved it I'll look again in /proc and /dev.

The router has a special setup for the GPRS modem through GPIO PINS to enable it (GPIO 1, 5,7) and the modem is connectet to UART0 (/dev/tts/0). The standard firmwares like Openwrt, Oleg, DD uses tts/0 to console output, you can compile firmware to disable kernel command parameters and to use the GPRS modem. I made it working just after installing the special BYTTON firmware, and installing Openwrt after it. I got modem ringing and displaying RING in minicom, I had no success with sending commands to the modem.
I tried various bauds with 8N1 mode, I will fight with it in the future, as I need to make a sms server on it.
If you want, I can send you the original firmware, maybe you'll get things working and maybe you'll help me to figure it out to!
I am from Romania, home country of topex routers

Thanks for the advice! I'm also Romanian They found a really strange way of connecting that modem. If you find the AT commands or a way to get it to connect please let me know.

i am also from Romania and i have some news regarding gprs modem and control over it.
First: it is posible to start the modem if GPIO 7 is on high level, but i don't know how to make this using openwrt, i don't know how to control the gpio pins
Secound: i have found a application that is designed special for modems to send sms messages

if anyone has any idee how to manual control the gpio pins please let me know

LE: GPIO5 is for controling the de status red led

in case your firmware is compiled with support for gpiolib and sysfs-gpio, you can easily follow those instructions: http://squidge.sourceforge.net/gpio/
if not, you probably have to go the way of gpioctl or find some entries in /dev.

i don't have any gpio in /dev , any ideea how i control ?
and also i don't have any gpio in sys/class/

On Deluxe, with backfire 10.03.1 k 2.6.32.27 I have just installed

opkg install kmod-gpio-dev kmod-gpiotoggling kmod-spi-gpio kmod-spi-gpio-old

and gpio apears on /dev
gpiodev in /sys/class/gpiodev/gpio/

lsmod | grep gpio
spi_gpio_old 2800 0
gpio_dev 2144 0
spi_gpio 3024 0
spi_bitbang 3088 2 spi_gpio_old,spi_gpio

I don't know what is the right module.

Have fun!
Eventual, rezultate daca reusesti ceva.

I am curios if somebody managed to compile a pfring + tnapi to get maximum speed on deluxe, pm me a link or some direction to start.

I have turned the red LED on with the following command:

gpio enable 1

It seems that the red LED is connected to gpio 1.
Turn off the red LED with the following command:

gpio disable 1

You will have to install the correct gpio for your kernel. I have Kamikaze 8.09.1, kernel 2.4.35.4 and I have downloaded it from http://downloads.openwrt.org/utils/gpio … .29.tar.gz

in that case, meaby that gpio 0 or 2 is the other gpio pin, for turning on the modem?
