After knowing how much the layout can and should be improved, I am still surprised that hacking the hardware with a 2 ¤ LDO chip was a sufficient work-around...

For balance, I should also say that I've sometimes had GPRS up and running successfully for whole days - e.g. for maps on long car trips. In summary, sometimes it works great, but I don't think you can completely rely on it.

It is, and it did :-) It should, of course, but still I rejoiced when finding it actually worked.

All I meant was that if you have any difficulty getting at the basic GPS info (in order to publish it as ROS), we can help with that. > Did the GPRS connection prove reliable enough for this? In my experience, sadly no. I've regularly seen problems at all levels, including - GPRS connection doesn't come up (especially - but not only - if after terminating a previous connection) - connection comes up but routing table hasn't been updated so as to route over it - connection up and routing correct, but /etc/resolv.conf is wrong so DNS doesn't work - connection, routing and DNS all look good, but for some reason data still doesn't get anywhere (or come back). One known underlying problem here is that the modem crashes if the outgoing data rate is too high. But I imagine that that is relatively rare in practice, so probably there are other underlying problems.

Re: Re: ROS on Freerunner
Hi Neil, hi Boudewijn, thanks for the suggestions. I understand that there are probably more usefull ways to get GPS info out of the Moko. Right now I'm trying it in the context of creating a complete ROS integration, so that all the phone's sensors will publish their information as ROS messages. This will be useful for using the phone as a control unit on a robot, but probably not for it's original intention as a phone ;) I think the one could easily forward the port gpsd uses to run tangogps on a remote PC. That's probably what you described, Boudewijn. Did the GPRS connection prove reliable enough for this? Jan Am -10.01.-28163 20:59, schrieb W. B.

Apart from exporting over Bluetooth, will you have an IP connection between the devices?

Re: [qtmoko]Problems with email client
Hi folks, I am currently testing v35 from sdcard, and I've got 2 problems with the email client. I cannot get all my emails from gmail through IMAP. I have to select a specific IMAP folder with few emails (<100) in order to see the client doing something. If I try to get all my emails, or if I specify a bigger folder (>1000) nothing happens. Too big ? Btw netstat tells me there is an established connection between my FR and imap.gmail.com, but nothing seems to happen. And then when I read my french emails there are some encoding problems. Does anyone know which package should be installed to manage ISO-8859-15 and UTF-8 ? Thanks in advance for any help, Xavier. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
