Well I'm the third guy here having issues using the app with a cell phone. A tablet is definitely worth a try. I'll go buy one at Walmart tomorrow, that would be so great!

Make sure the dip settings are correct on the 1320 box. I have also found that sometime with Bluetooth you need to restart the process to connect, I personally prefer the cable, but the Bluetooth is nice.

I shipping example with ALDLdroid is for a 1990. I worked with Sebastian when he was developing the app. Works on my Nexus 7 first and second generations

Update:

Tried a cheap RCA Voyager III tablet this morning and it works flawlessly! For some reason it doesn't seem to work on most cell phones...

On GearHead EFI forum, there is a big thread about the app but nothing seems to be covering the issue here.

Maybe it could be interesting to create a compatibility list like this one:

Green works fine.
Red doesn't work.

Amazon Fire 7
Google Nexus 6P
Google Nexus 7 1st Gen
Google Nexus 7 2nd Gen
RCA Voyager III
Samsung Galaxy S4
Samsung Galaxy S7

I have found Samsung phone products to be glitchy in general. Had a few a couple years ago when they were touted as the greatest thing since sliced bread. Nothing but problems. Went back to my iPhone and IPad. I really wish the app had been developed for iPad.

Resurrecting this post from last year.
I recently acquired a 1320 ALDL Bluetooth Adapter for use with a Samsung Galaxy Tab A (2016) model SM-T280 tablet and ALDLDroid app. Tried a few ADX files from the internet and still having a lot of
“Checksum Mismatch/incorrect response length from the ECU”
errors along with garbage data being displayed.
I've gone through the tips members have provided here on the forum and also contacting John Wales at 1320 but so far no success. For reference this setup appears to work fine using the 1320 ALDL Scan app.
Anyone have an idea what could be going wrong? Car is a 1994 ZR-1.

Phil,

Are u using the $F0 adx? Also, under settings, u need to disable the checksum.
I have been using an ASUS tablet for several years w the Red Devil BT ALDL.
WORKS FINE. A few times I may need to restart but once it connects, its pretty flawless. Also have found that It works well after disabling WiFi and enabling BT.
Sometimes a stray network will interrupt logging so I shut it off while driving.

Give me a shout Phil if ur still having an issue. I visited w Gary in WI who was having similar issue using Samsung. Turned out it was his Samsung phone he was trying to use. Perhaps Samsung’s “version” of Android could be an issue.

As I mentioned, I had LOTS of emails with John Wales/Sébastien Giroux and we never managed to get it working correctly on my Samsung S7.

-=Jeff=- · 10-12-2019

Whose ADX file are you using?

Jagdpanzer · 10-12-2019

Jeff,
I’ve tried the FO adx file you posted up a while back and one John Wall sent me.
