Re: xiaotec "850 OBD-II" Android app on Google Play for '96-'98 850/S70/etc

Post by Geevs » Fri May 03, 2019 12:19 pm

Hi, I also purchased the latest version of the app (April 11, 2019) and it doesn't connect or scan anything. In comparison, Torque Lite and Car Scanner (both Android apps) work fine on the same device and BAFX BT ELM327 adapter.

The app's bluetooth screen, it shows my OBDII device as "in use", so I assume that the app has connected to it. However, the scan, connect and play/start buttons in various sections of the app don't work or respond as expected.

Can anyone give advice on how they managed to make the app connect with their BT adapter and get a meaningful response? I'm trying get the stored mileage on the odometer.

Thanks!

In "850 OBD-II" app, the "in use" description on the Bluetooth page seems to really mean "last paired Bluetooth device" (I think). In my experience, it definitely does **not** mean "connected". [Maybe item 3 below will help shed some light -- Easiest way to connect is to press triangle icon between Info icon and Bluetooth icon, then wait a few seconds.]

I've used BAFX BT with both V1.1.6 (2019-01-03) and V1.2.7 (2019-04-11) of "850 OBD-II".

I've also used OBDlink MX+ with "850 OBD-II" V1.2.7 (2019-04-11) using the factory v4.5.12 firmware that came with the OBDLink MX+.

1. What kind of vehicle are you scanning?
What kind of phone are you using?
What version of Android are you running?

2. Today, I used my BAFX with "850 OBD-II" V1.2.7 (2019-04-11). It worked without jumping through any hoops. [I changed my Bluetooth device from whatever string represented the OBDLink MX+ to the "OBDII" device. I actually pressed it twice. Once, which exited the Bluetooth page, then I entered the Bluetooth page again and saw "OBDII" device was "in use", then pressed that device's description again.]

3. Here's a short summary of what I did...

After selecting the "OBDII" (ie, in your case BAFX) device using "850 OBD-II" app's Settings / Bluetooth function, and seeing it is "in use", then return (via your phone's Back button) to the screen that shows the line "Live / Service / Settings" at the bottom. Now at the top of that page, press the right-facing triangle that is between the circle-i (Info) icon and the Bluetooth icon. Wait a few seconds for the uncolored right-facing triangle to become two green vertical bars that indicate "your BAFX is connected". Then click the Service button at the bottom center of that screen. Then click the Scan button at the bottom left of the Service screen. Wait several minutes for the Scan to finish -- during which time commands/requests and their responses should be near continuously be appearing and scrolling off the display. Then click OK, click Back, and hopefully you are back at the Summary page.

4. If that doesn't get you up and running, I can post a much more detailed list of the steps I followed. But I'm guessing that "pressing the triangle button" is the hint that you needed -- since I also had to have the developer clue me in to connect that way.

5. By the way, my phone runs Android 5.1. I believe the "850 OBD-II" app's Info page explains the app's required minimum Android version. If you have a very recent Android version, maybe the app doesn't yet run with that, and you'll need to email the author to get the app running on your phone.

The bluetooth connection is buggy. Shut down all other apps that use that connection. Delete the bluetooth pairing. Reboot the phone. Then try pairing 850 OBD-II to the ELM327.

Another option is to use install NOX Android Emulator on a PC or a Mac and run 850 OBD-II isolated from the other OBD-II software. You can run 850 OBD-II on multiple devices if they are connected to the same Google account.

Hi all,

I have tried all suggestion from this forum and also from the app developer who responded to my email. I tried the suggestions on 2 phones and 1 tablet and the app still won't work. However, other apps like Torque and Car Scanner continue to work.

Interesting, this app messed up one of my phones causing it not to boot up. Fortunately, this was on a backup phone running Android Pie. Now I wonder if this app is a rogue app with malware in it.

I've unisntalled the app from all my devices.

BTW, I'm running the latest version 1.2.7 released on April 11, 2019.

Cheers,
Geevs

Hi all,

I've been emailing the app developer and he says his working on improving the BT connectivity of his app and plans to release an updated version soon.

In the meantime, I was able to obtain the mileage of my 850s using a Linux-based python script (mentioned one of the other threads in this forum) and a BT ELM327 adapter.

Question now is - after I replace the broken odometer gear in the cluster, how does one update the odometer itself to match the mileage stored in the cluster?

Thanks!

That is a YouTube video that MVS's rspi did in early 2019 showing the quickest way to read the '96-'97 850 mileage from VDO clusters using "850 OBD-II" Android app V1.1.6. The method also works for the '97-'98 S70/V70/C70/XC70 Yazaki clusters.

Thank you, Robert!

In response to a post in another MVS thread, I thought it best to put this info here in this thread dedicated to "850 OBD-II"...

The "850 OBD-II" Android app was developed by Aleksi Venäläinen from Finland.

He used some 850 info at jonesrh.info's Volvo 850 OBDII portal to develop an "850 OBD-II" beta version. Once I saw he was serious, I gave him the internals of the jonesrh KWPD3B0 interpreter that deal with interpreting the raw DTC codes that translate to the 3-digit Volvo DTC codes like:
- CI-221 -- Vehicle Speed signal missing [usually due to bad ABS module solders]
- ABS-311 -- Left Front Wheel Sensor, open/short [or bad ABS module solders or ignition switch]
etc. From there, he kept adding facilities.

Now -- as of the "850 OBD-II" V1.2.9 [2019-06-07] release -- there are several ways that the "850 OBD-II" app has surpassed even the recent volvo850diag v0.9 [2019-07-14] release:

1. "850 OBD-II" app can perform realtime interpretation of the data it receives from the '96-'97 850 and '97-'98 S70/V70/C70/XC70 !!!

volvo850diag, on the other hand, is a relatively "dumb" program in the sense that it does *NOT* interpret the data from the car. Instead, the data is logged, then (as of 2019-08-10) it must afterwards be interpreted by submitting to the jonesrh KWPD3B0 interpreter page.

2. The latest (as of 2019-08-10) "850 OBD-II" app V1.2.9 scans several more ECUs -- eg, the ones specific to the C70 -- compared to the latest (as of 2019-08-10) volvo850diag v0.9 version.

3. Even though "850 OBD-II" app originally used the 2 hex digit raw DTC <-> 3 decimal digit Volvo-specific DTC codes association provided by jonesrh, the most recent versions of "850 OBD-II" app includes more DTC data for more ECUs, and the app includes much better raw DTC to 3-digit Volvo DTC associations for AW 50-42 (ECU 6E) DTCs -- compared to what jonesrh KWPD3B0 interpreter does.

4. The latest (as of 2019-08-10) "850 OBD-II" app V1.2.9 can perform testing of components in MSA 15.7 (ECU 11), AW 50-42 (ECU 6E), and ABS (ECU 01). That's something that volvo850diag v0.9 can *not* do.

5. "850 OBD-II" performs Live data scanning of individual ECUs much faster than volvo850diag.

Aleksi (or his company) is known as xiaotec on the Google Play xiaotec "850 OBD-II" page.

He has (or had) a presence other places on the net as XantheFIN.

He has introduced himself to the MVS community as "xanthefin" in the thread
viewtopic.php?f=1&t=89530 and in a few other MVS posts.
