I'm an old skool coder (anyone remember BT Wireplay?) who is seriously miffed that all my previous mobile phones have never quite done what I want, have never quite had the right (cf: up to date) software standards that let me develop fun apps and I couldn't do anything about it except spend more cash. Not any more.. mwahaha...
Looking forward to getting a Sat nav, VoIP handset, gaming platform and GSM communication tool in one cool little package :)
I finally got my grubby mitts on a Neo1973 today - w00t!
- 0 - turn it on - yay it boots, loads a kernel and stops as expected :)
- 1 - flashing the right rootfs / kernel - used 26th July files from chooseopen.com, held breath and cut/pasted dfu-util commands, then rebooted... it's ok!
- 3 - insert sacrificial SIM (UK T-Mobile) and SD card
- 2 - Test hardware:
- 2.1 - well the CPU and display are ok, as are the Flash and RAM it seems
- 2.2 - Copy mp3 file onto media card (using scp), play back with madplay - audio and SD card interface ok
- 2.3 - Fire up libgsm-tool -m shell, attempt to power up GSM and register SIM - failed :(
- 2.4 - Remove SD card, reseat SIM and try again - ok
- 2.5 - Call mobile number - enjoy moment of nostalgia as RING appears :)
- 2.6 - Answer call, no audio but that's expected - GSM chip ok
- 2.7 - Just for fun call another mobile - also connected ok
- 2.8 - Check time, 02:04hrs go to bed happy!
NB: Must test GPS if possible (looks tricky ATM)
Take new toy to office (BT Labs, UK) and show off :)
Try to join mailing lists - not working it seems, go to IRC channel instead.
Managed to join the appropriate mailing lists (thanks to whoever resurrected mailman)
Have now discovered just how long the Neo currently lasts without a USB umbilical attached - about 2-3 hours.
Much poking about on the Wiki to see where I could help with the power management, and playing with the power monitoring script available there.
Discovered I can change the backlight level by writing appropriate numbers to the /sys control file - handy when it gets dark and I don't want my eyes fried!
Neo now permanently attached to my PC, since the kids use the PC a fair amount during the day while I am at work, thus keeping my Neo alive :)
Thanks to the mailing lists, it seems OM 2007.2 has better power management, so that's going on the phone tonight..
Cool! I put OM 2007.2 build 20070825 on this morning (following the instructions here Phase_1_Software_Testing), and I have a working GSM phone :) I've made a call both ways, incoming seems to work until you hang up at the remote end, after which the phone and / or gsmd doesn't recognise the RING signal. There does seem to be some interference from the GSM radio audible in the handset, perhaps I have a poor signal here and the radio needs more power than other people?
Power management still not done it seems: I had OM 2007.2 20070818 on the phone for a couple of days, and tested leaving the phone running overnight with 'Full PM' enabled - by morning it was flat (about 8 hours).
Jobs for the bank holiday: getting a development environment set up so I can actually have a go at building my own binaries... bye bye disk space!
More good news: OM 2007.2 build 20070825 seems to have sorted out the power management problem: leaving the phone 'on' with Full PM enabled overnight and it had 80% charge left the following morning :) I've noticed that on resuming from suspend mode, the system clock isn't updated from the hardware clock... I brought the phone into work again yesterday, but the GSM failed to work for me at lunchtime, and I was unable to get any logs without attaching to a USB host.
