ALDLdroid help
I got ALDLdroid running on a cheap Android tablet using the 1320 Bluetooth adaptor.
The problem I'm having is an intermittent "checksum mismatch". Anyone know how to solve this? I'm using an LT5 adx file I received from another member here. Car is a 92. Thanks.

Re: ALDLdroid help
Turn off the Wifi so it’s not hunting for a wifi signal and let it run on Bluetooth only.
You may find you have to disconnect and reconnect a few times before it takes. I have the same issue with mine. H

Re: ALDLdroid help
I get that too, but i, running an adx file that 1320 sent me. The app that they have seems to be a little more stable but will also drop out.

Re: ALDLdroid help
Yeah.. connect disconnect a couple times seems to clear it up.. problem is with the silence commands at the beginning.. trying to get the CCM to stop chattering

The checksum confirms the data packet to be correct. Otherwise you might get the wrong values

Re: ALDLdroid help
Interesting, maybe it is a bogus checksum error. I have been playing with an arduino to get messages off the bus. I see the chatter and was trying to get data with the chatter but that may not work. I am going to set up a test bench with a CCM and ECM. If there is a better way to silence the CCM or insert the request message with chatter it would be nice. I also found what part of the chatter is, but need to see if I can find the rest..
