Problems reading from 0411 pcm

[pmcquay]

Good morning,

I purchased an 0411 pcm from the man Lextech himself some time ago, and just now am I getting around to playing with it. I built a bench harness and tried to read from it with my OBDLink LX. I am having some problems.

1. This device creates 2 com ports when its paired to my windows 10 surface 3 pro. In the bluetooth device properties under com ports one is listed as outgoing and one is listed as incoming. Selecting the wrong one (?) causes PCM Hammer to lock up. I got around this by removing the incoming com port. This appears to have made this part work, but may have caused the issues I see in the next part. Is there some way to know which port is correct? Is there some way to stop selecting the wrong port from locking the program? Is there a way to erase the settings so that the program doesn't automatically select the wrong port at startup? (this was especially annoying)

2. I got it to successfully read the bin (attached), but it appears to not be getting the correct response while doing the CRC check (debug log attached) Its looking for an "OK" but gets nothing. Is this a known problem? Could it be caused by my solution to #1? I wouldn't expect removing a com port it isn't set to to cause a problem.

Looking at this bin in tunerpro it appears to have read correctly, but I don't think I'm going to use this to write until I can get a fully successful read.

It appears the connection dropped just prior to [09:57:13:753] Did not recieve expected response. Received "" expected "OK"

Please verify your wiring connections are solid and that the bench harness follows this schematic here: https://pcmhacking.net/forums/viewtopic.php

Reality is, it's likely a Bluetooth issue, it's not very reliable.
Out of the two ports only one works ... Use it.

Can you try it back to back with complete reboot in between and see if it happens at the same point each time.

You can use the `Test File Checksums` options under the Tools menu to check the file.
The read was most likely good.
You can also use `Verify Entire PCM` against that file to verify it's exactly the same as the PCM.

To delete PcmHammers persistent storage delete the folder: %localappdata%\PcmHacking
Nothing to lose, it will all get recreated upon next launch except for the few user options/settings.

Ive never liked bluetooth. Never seen a good implementation, even with quality devices. Is there a wired device I can get without spending $texas and that isnt slow as balls?

I will try it again, and I've confirmed that my harness is correctly wired.
