If you're buying an Android phone to use with RaceChrono, you can ask here how it works. Also if you have enough experience on a phone to recommend it to be used wit RaceChrono, please do!
- Samsung Google Galaxy S (Android 2.3.6, 4.0 and 4.1)
- Samsung Google Galaxy Nexus (Android 4.0 and 4.1)
- Samsung Galaxy S3 (Android 4.0 and 4.1)
- Asus Google Nexus 7 (Android 4.2)
- QSTARZ BT-818X (5 Hz)
- Garmin GLO (10 Hz GPS / GLONASS receiver), works well with Android 2.3, 4.0 and 4.1. Also 4.3 works but needs RaceChrono v2.43 or newer. The device has slight update rate problem when used with Android, the update rate in reality fluctuates between 5-10 Hz.
- Dual XGPS 160, so far seems to work perfectly, steady 10 Hz and locks to 20 satellites (GPS + GLONASS)
Works mostly fine but some problems:
- QSTARZ BT-818XT (10 Hz), frequency problems on some phones. If having such problems, switch to 1 Hz so RaceChrono will use the device as 5 Hz.
- ZTE Blade mk1 (with Android 2.1), Bluetooth hangs regularly, so using Bluetooth GPS is not an option with this phone. This is a hardware/firmware problem, nothing I can do.
JuhaK: I have ZTE Blade mk1 (with Android 2.1) and it works fine otherwise, but Bluetooth hangs regularly after 20 minutes, so for me it's pretty unusable. As I don't like any internal GPS. Someone needs to test the more common Blade mk2 (with Android 2.2).
I've never seen a Bluetooth hang on Samsung device. Sure the phone crashes sometimes but not regularly at all.
So if you didn't buy the phone, I'd try something else. Galaxy Y is cheap but the resolution is not very good. Maybe the rugged XCover with 480x320 resolution would be a good choise? It is 210 euros in local Gigantti.
This is while used with a Qstartz BT-Q818XT via bluetooth.
HTC Legend + Q818XT - Won't Pair
HTC Legend + Q818XT + CyanogenMod 7.1 - Pairs fine, but frequent drops / RachChrono stops recording randomly.
HTC Legend + Q818XT + CyanogenMod 9 - Pairs fine, but frequent drops / RachChrono stops recording randomly.
So not the phone for you ...
Anyone know something cheap that just works ? Was trying to get my mits on a Galaxy S Wifi Music player as that has bluetooth and would probably do the trick. Failing that anyone tried the Huawei Ascend G 300 ? Seems the best cheap phone buy at the moment.
Racechrono is working without noticeable issues. No bluetooth drops.
Using good external antenna and getting very precise results.
Have not tested internal GPS.
Asus Nexus 7 - This is while used with a Qstartz BT-Q818XT via bluetooth.
Used on five track days on four different tracks so far.
Running ICS 4.1.1
Samsung Galaxy S (2.3.6) with iBT A+ GPS and RaceChron 2.11 (and earlyer version) : works perfectly
Samsung Xcover GT-S5690 (2.3.6) with iBT A+ GPS and RaceChrono 2.11 : bluetooth is ko ! It ask me to appaired all the time... it 's the same with the app Bluetooth GPS. And not function at all with bluetooth gps provider or bluetooth gps mouse.
It's also fully functionnal with HTC Wildifre and iBT A+ GPS.
I don't know what to do...
It's ok with internal GPS but not terrible...
Goog job for RaceChrono
Someone want to buy a xcover ?
RaceChrono, Defy and GPS, It is a good set at a good price !
Thnak a lot for your work.
I have an HTC One X with ASOP Rom (its pure Jelly Bean v.4.2.1).
Can someone please tell me which BT GPS Receiver I should buy in order to get accurate lap times?
I'm going to Serres Race Track in Greece on April and would like to test the software, I'm going to have a professional transponder on the bike so I would be able to see how accurate Racechrono really is and report back here :)
Someone suggested me to buy a BT-Mini Mobile GPS Receiver for like $15 but I think it won't do the job.
Thanks in advance for your help!
(GPS receiver is QSTARZ 818XT)
I have a Galaxy S2 with RaceChrono v2.21 has any one had good reliable pairing results with Qstarz BT-Q818XT 10Hz for lap timing in a closed race car, or would I need and external aerial
Sorry for my bad english !
RC (Android) works very well on an Samsung Galaxy Ace with the iBT A+ GPS, thank you for this brilliant program!
I however miss " 0/100.... ", and in navigation, no possibility to see the speed.....(just see the satellites).
Before getting the GLO I found the QSTARZ BT-818XT (10 Hz) a bit erratic at both 5hz and 10 hz frequently dropping sat lock leading to some very strange looking lap traces. The GLO is superb, usually getting a lock on 15-19 satellites, and always running at 10hz.
Don't think blue-tooth related, since live timing worked perfectly, showing lap times, splits and sector +/- times. After ~10 laps / 20 mins, I opened the session to analyse and it only showed the out lap and one more lap?
One extra issue was the screen locking after 10mins. Phone can be set to 30mins which may help.
