Last I checked, the wifi was non-functional under Linux.  Unfortunately, that suggests that it doesn't have open drivers, but perhaps it was only a temporary situation.

At least GPS and GSM are indeed serial data interfaces but not black-box modules. I have added the link to the data sheets (which include the AT command set) on the main page. [[User:Hns|hns]] 17:37, 7 November 2007 (GMT)

Wireless LAN
 +
Wireless LAN on EM-X270 supports 802.11b. Currently Angstrom Linux for EM-X270 does not enable
 +
this interface automaticaly. The driver for wireless LAN chip present on CM-X270L is provided by the
 +
chip manufacturer and therefore redistributed by CompuLab in binary form. The driver is called bgw200
 +
and can be enabled using
 +
echo 1 > /sys/devices/platform/wlan/pwr_on
 +
modprobe bgw200
 +
iwconfig eth1 essid <your_ESSID>
 +
You can use Linux standard iwconfig, iwscan, iwevent, iwgetid, iwlist, iwpriv, iwspy utilities.

I have been in contact with the one responsible for Germany/Austria. They just act as a sales agent and handle the import - but it does not change the sales policy. I.e. you still have to be a company and order an evaluation kit and have the price scales. So the approach is to have Handheld-Linux Shop to work as an intermediate to collect individual orders (worldwide), keep away warranty issues etc. from CompuLab and issue a single order towards CompuLab. So if we split up this into many resellers with small quantities, the price will not go down. [[User:hns|hns]]

that's a bit shitty - they're not playing easy are they. one would think they don't want to sell any anything. well, i dug a bit and it appears we at least don't have to buy an eval kit for 2000 if we claim non-commercial [http://www.compulab.co.il/sales-and-support/non-commercial.htm as seen here] [[User:Myfanwy|myfanwy]] 08:09, 8 November 2007 (CET)

[edit] open-source drivers

is there any word on the openness of drivers? a big part of the appeal of the neo is that the majority of the drivers (where legal) are open-source. any widespread adoption of these modules will probably stall straight away if there are no open drivers/useful documentation available myfanwy 00:59, 7 November 2007 (CET)

They provide the Angstrom Linux which is based on Open Embedded. So I would assume that drivers are the standard drivers of the Linux kernel. Well, WiFi, Bluetooth, GPS and GSM may only be available as (USB) serial data interfaces to some black-box modules. hns 17:37, 7 November 2007 (GMT)

looks like the wi-fi driver will be binary only: [1] that page has more info on drivers, etc. for the cm-x270 (similar to the em-x270) and other compulab boards myfanwy 23:25, 7 November 2007 (CET)

[edit] emulation

in lieu of developing on actual hardware, an emulator would be mighty useful. does one exist for the compulab hardware? is it much of a process to put one together? myfanwy 01:22, 7 November 2007 (CET)

[edit] Case

The device is a "pure" module with everything except a case. To get one, we will need

  1. someone who can make a mechanical construction
  2. someone who can nicely design it (and decide about colors, materials, haptics)
  3. someone who can produce low quantities at a reasonable price (< $50 per units)

Ideas? Proposals? Links? Friends? Volunteers? hns 17:37, 7 November 2007 (GMT)
