15:01.01atkDamn
15:01.20atkI think some of the balls on the BGA chip on my N900 have cracked.
15:01.26atkI'm getting those infamous sim card issues.
15:01.54atkI guess it's time to find an old dried up pen and cut the spring into some pressure thingimajigs.
15:04.42DocScrutinizer05I wonder if there's a way to check what really defect
15:05.17DocScrutinizer05at least SIM contacts should show some electrical properties different from dangling wire
15:05.41DocScrutinizer05but there are so many more BGA ball connections on modem
15:06.04DocScrutinizer05first you might check if modem still responsive at all
15:06.09DocScrutinizer05pnatd might help
15:06.51DocScrutinizer05if you can talk to modem, you cpuld query quite a few status-related infos
15:07.33DocScrutinizer05like generic access to SIM, available networks (antenna / generic RF frontend)
15:09.21atkIt works when I reboot the phone
15:09.48atkbut I dropped my phone on a hard floor about a week ago and now it just stops working randomly until a reboot
15:09.59DocScrutinizer05hmmmm
15:10.08DocScrutinizer05not good
15:10.23atkyeah, I'm pretty annoyed about the drop, it worked perfectly well before then.
15:11.34DocScrutinizer05maybe first of all check signal quality to verify the mere antenna thingie has cobtact to the PCB
15:12.35atkhow would I check the signal quality? When it works I get 5 bars.
15:12.53DocScrutinizer05it's a C-spring that sits on a copper (gold?) pad for years. collecting dirt and oxides around the contact point. Now a hard impact could minimally relocate the C-spring contact point, right into the dirt zone
15:13.07atkhmm
15:13.50atkMight be, the phone I took this motherboard out of literally looked like someone had shoved it up a car exhaust pipe for a week
15:22.30Joerg-Neo900no tracking
15:22.34Joerg-Neo900no iinsurance
15:22.41Joerg-Neo900oops
15:27.35Joerg-Neo900please first try pnatd something like "ATI"
15:28.38Joerg-Neo900the AT-interpreter in BB5 and pnatd is pathetic, but a few useful data bits are available for sure
15:32.08atkATI just gives "Nokia"
15:32.20atklol
15:32.33Joerg-Neo900https://i.imgur.com/Phpr47G.png
15:33.16atksame on my screen
15:34.05Joerg-Neo900so the modem is up and running and the comm lines to OMAP are working
15:34.53atkhmm
15:35.34Joerg-Neo900https://radekp.github.io/qtmoko/api/atcommands.html
15:35.55Joerg-Neo900haha radekp/openmoko  how funny I didn't even see
15:36.53Joerg-Neo900at+cfun?
15:36.55Joerg-Neo900+CFUN: 1
15:37.23Joerg-Neo900at+cfun=?
15:37.24Joerg-Neo900+CFUN: (0,1,4),(0,1)
15:38.06Joerg-Neo900=?  is "what are the allowed parameters?"   ? is "what is current state?"
15:38.30Joerg-Neo900+CFUN is current state of modem
15:38.45Joerg-Neo900related e.g. to airplane mode etc
15:39.16Joerg-Neo900AT+CSQSignal quality
15:39.43Joerg-Neo900ERROR on N900
15:39.57Joerg-Neo900what a crippled AT interface
15:40.04atkhmm
15:40.13atkon mine at+csq gives: +CSQ: 99,99
15:40.35Joerg-Neo900ed
15:40.49Joerg-Neo900what the
15:40.59Joerg-Neo900Oh I see, no "?" needed
15:41.24Joerg-Neo900+CSQ: 15,99
15:41.35atkhmm
15:41.42atkso 99 probably means the worst signal quality possible?
15:41.43Joerg-Neo90099 is prolly same as "no signal"
15:41.47Joerg-Neo900yes
15:41.51atkI'll open it up and look at the aerial thing
15:42.01Joerg-Neo900:nod:
15:42.14Joerg-Neo900check SIM maybe
15:42.22Joerg-Neo900moment please
15:43.47Joerg-Neo900AT+CIMI
15:43.49Joerg-Neo900262074910014095
15:45.50atkI get an error
15:49.27Joerg-Neo900https://www.sierrawireless.com/resources/documents/support/2130617_supported_at_command_reference-v2.4.pdf
15:49.42Joerg-Neo900error means you're not logged in to network
15:49.54Joerg-Neo900this command queries IMSI
15:51.53Joerg-Neo900AT+CNUM   my own number
15:52.15atkalright, which contact is the one for the antenna?
15:52.53Joerg-Neo900there's a "contacts" whitepaper n resources IIRC
15:54.21Joerg-Neo900http://neo900.org/stuff/werner/springs/
15:55.16Joerg-Neo900P703/4/5
15:56.59Joerg-Neo900atk: you found it?
15:57.09atkyeah
15:57.10atkI found the 3 contacts
15:57.30atkjust scraped at them with a precision screwdriver, we'll see what happens
15:57.33atkthey were all quite dirty
15:58.00Joerg-Neo900check the pads in antenna plastic blob, they often look really terrible
15:58.18Joerg-Neo900ought to be gold plated and shiny
16:00.01Joerg-Neo900suddenly got an idea of the real reason the manufs opted for watertight smartphones: suddenly no more problems with dirt inside device, at all
16:02.14*** join/#neo900 _Chris_ (~Chris@p5DE1A05B.dip0.t-ipconnect.de)
16:02.14atkLooks promising, I got network time on the boot screen.
16:02.24atkWell, I have a network connection again
16:02.34atkI'll use it for a day and see if it breaks again.
16:02.35Joerg-Neo900:-D

16:34.40sixwheeledbeastcheck battery  antennas and sim tray are not damaged or loose from the drop
16:39.22*** join/#neo900 _Chris_ (~Chris@p5DE1A05B.dip0.t-ipconnect.de)
16:48.30atkthe sim tray is as loose/tight as it has ever been
16:48.38atksame with battery
16:48.45atkbut yeah, the antenna contacts seemed a bit dirty
16:49.18atkand this phone has been in use for like 4 years now
16:49.30atkand probably 1 to 3 years by the original owner?
16:49.32atkmaybe more
16:49.45atkactually, when I got it, it looked like the original owner had installed a new kernel so maybe he was a power user
17:37.35*** join/#neo900 rEv9 (~rEv9@unaffiliated/rev9)
17:45.33rEv9Joerg-Neo900: you should update the webpage/topic with what you said on http://maemo.cloud-7.de/irclogs/freenode/_neo900/_neo900.2019-04-15.log.html  -- that you're looking for someone to work on the proto_v2 layout. maybe someone else can help out ?
17:45.57rEv9I miss using my N900 :D
17:55.33Joerg-Neo900rEv9: sorry, the time was faster than Neo900 evolution. The project isn't really plausible anymore. Too many roadblocks that can't get overcome, unless we would find a sponsor for STEP2
17:57.24Joerg-Neo900even if we could finalize layout for proto_v2, we have no more funds to build it, and even if we coould build it, we couldn't find enough mech-kits (display, case etc) to produce the number of devices needed to break-even on production cost

17:58.44Joerg-Neo900too many prospect customers thought they better wait until we're shipping before they place an order
17:59.07Joerg-Neo900now it's too late, the opportunities dwindled
18:16.57rEv9Joerg-Neo900: I understand :/
18:46.50Joerg-Neo900it's a pity. Sorry for not having better news
