[26.Aug.2011][Dev] GPS Libraries v2.1 with AGPS support for HD2 Gingerbread
- Thread starter tytung
- Start date
- Status
Please use adb to run the following commands.
And did you see this folder /sdcard/libgps_with_AGPS_update?
any chance that time might be off for some people by an hour because of daylight saving not being included in calculations?.
AMSS is just a high level number to distinguish different devices.
GPS mainly depends on the server RPC calls. (a low level thing)
AFAIK, server RPC calls are determined by radio. Correct me if I'm wrong.
GPS is using HAL library, and is 100% not related to the kernel.
My source code (libgps) is a HAL library.
Qcom source code (libloc_api) for Gingerbread is also a HAL library.
I have better GPS development experiences than him.
If you don't modify libloc_api, I believe only changing the kernel is helpless for GPS.
Tytung,

Fixes the time offset for me. Could you test if this effects your displayed time.
Or anyone can just grab my version and test it and check if this repairs your time or wrongly displays the time now if you had the correct time displayed.
i can confirm that arne182 libs show for me the correct time.i test it with gps status.with v1.4 tytung it shows the last fix was 20.57 but the time here now is 21.57.with arne182 v1.4.1 libs gps status shows correct 21.59 for last time fix

It's correct to set it to 0 in order to support Daylight Saving Time according to the definition of mktime().
I changed my code and the time was still correct for me.
v1.5
Version 1.5 - (Jun. 26)
Thanks arne182 and clio94.
Version 1.5 - (Jun. 26)
- Support daylight saving time (DST).
Thanks arne182 and clio94.
Yes I totally agree with you Tytung. That's exactly what I meant. I hope the way I said it wasn't offensive sounding? When people like myself are testing, 1 single test is not good enough because of the above external situations you mentioned. Thanks for all your hard work.

Could you check if your height in v1.4+ is now correct in GPS Status. With the new nmea method it should be correct height but I have no way of testing this.
TYTUNG V1.5 - First test indoor near window overcast day.
- Your V1.5 instructions are excellent! That's what some of us needed.
- the Gscripts worked perfect and easy. No issues at all.
- used LibTestMode COLD (16hrs), locked in 18sec with 6 sats and at about 30secs or less, locked 10sats which is turbo fast!!! (checked with Ulysse immediately after with instant locks of course)
- location time is CORRECT! Altitude seems closer to what I see on an altitude map. Has that been fixed too?
- testing 10min later...8secs lock with 6-8 sats
- then 1min later...6secs lock with 6-8 sats
- then 10-20secs later...2-3secs lock with 6-8 sats
- NOTE: I have AngelDeath's Location script for my region loaded in gps.conf
- UPDATE: not sure if this is directly related, but my Google Maps position seems better. We will see if that remains consistent over the next 3 days.
- UPDATE Over 1 hour later, on the train, where i normally struggle to get a fix...i got a fix in under 10secs. WOW!!!
- UPDATE: Hours later in an indoor area of known terrible reception, i got stable fix in under 2min. pretty darn good.

Tytung,
Here is my early summary of using v1.5:
1. Time to first lock indoor near a window approximately 13 seconds. Received clear signal of 9 of 11 satellites.
2. Couple of hours later retested outside, clear skies. Lock was in 5 seconds with clear signal of 7 of 9 satellites.
3. Waited ten minutes, lock in 2 seconds. Relocks are immediate.
4. Altitude is very close to actual. Using GPS Status I see a range from 230-233 feet, actual is 231 feet.
5. Accuracy on Google Maps is 5 meters.
6. Time on GPS Status is now correct for my time zone. No more 1 hour behind.
7. Compass on GPS Status pointing correctly as it did since v1.1.
Seems for me, this newest edition works extremely well. Didn't need to use QBANIN GPS Fix. Looks like I may remove it from my phone real soon.

hi
thanks i reread instructions for 1.5 and realized i didnt have libgps _with_AGPS_update installed on my card.
sorry for the confusion.
thanks
Applied gscript files. After 1st one, it loads then reboots to lock screen and keeps rebooting. What did I miss?
Follow the steps of the post #791. Works for me and it's incredibly fast satellite lock
If this work for you please hit the thanks button

265This implementation is based on GPS Library in HTC-HD2 Android Libraries. (Thanks to dan1j3l.)
You can find my modified source code and AGPS development info in the second post.
Downloads:
Mod edit: Links removed
You can install GPS Status & Toolbox or GPS TEST to test the new libs.

Leo AGPS Injector is an Android app for quickly injecting NTP time and AGPS xtra.bin data, and lets you explicitly know when the AGPS data is injected.
- Manual execution: Run this app to finish the AGPS injection task manually.
- Auto execution: Use Script Manager(free app) or Tasker(paid app) to schedule the routine task by using the script below or using any similar method.
agps_injection.sh
Code:am startservice -n leo.android.agps/leo.android.agps.AGpsService
Changelog:
- v0.5:
- Add a network check for refreshing widget's injection time only if connecting to a really available network. (i.e. can download xtra.bin and get NTP time)
In v0.4, it will still refresh the time even if you are roaming and disable data roaming. (Under this situation, you cannot download anything but this app doesn't know.)
- Add a network check for refreshing widget's injection time only if connecting to a really available network. (i.e. can download xtra.bin and get NTP time)
- v0.4:
- Merge versions 0.3 and 0.3a:
Add a check box for determining if showing the setting dialog every time when running this app.- When you uncheck it and run this app again, it will inject NTP time and AGPS xtra.bin data, and then destroy this app by itself. So you won't see any UI.
- When you uncheck it and leave this dialog, you must go to [Settings]->[Applications]->[Manage appliciation]->[Leo AGPS Injector], and press "Clear data" to get this dialog popped up again.
- Merge versions 0.3 and 0.3a:
- v0.3:
- Add a widget for quickly injecting NTP time and AGPS xtra.bin data.
- Display the last injection time in the widget.
- Include three types of notifications: Notification/Status Bar, Pop-up message, and None.
- v0.2:
- You can choose to see the real injection time in the notification bar or to be notified through a pop-up message.
- v0.1:
- If you network is unavailable, this app will run as a background Service and passively wait for the connectivity change notification from the Android.
- Besides, you can see the "Waiting for an available network." message in the notification bar.
- When you network is available, this app will download and inject NTP time and xtra.bin, and then the Service will destroy itself to free the memory, so this app won't occupy your memory.
- Besides, you can see the real injection time in the notification bar, and you can clear it if needed.
- If you network is unavailable, this app will run as a background Service and passively wait for the connectivity change notification from the Android.

I changed this line in gps_xtra_set_data from leo-gps-rpc.c.
from:to:Code:res = pdsm_xtra_set_data(_clnt, 0, client_IDs[0xb], 0, xtra_data_ptr, part_len, part, total_parts, 0);and agps appears to be working. I have uploaded the modified libgps.so in tytung's zip package just replaced the libgps.so. I was wondering if people would try it out.Code:res = pdsm_xtra_set_data(_clnt, 0, client_IDs[0xb], 0, xtra_data_ptr, part_len, part, total_parts, 1);23If you want to enable xtra.bin download requests and set download interval, you need to modify gps.conf.
Set GPS1_XTRA_AUTO_DOWNLOAD_ENABLED to 1 and set GPS1_XTRA_DOWNLOAD_INTERVAL to 24 hr or whatever. (range is 1~168)
