Sparkfun WIG 09555 question

Postby onebrasssoldier » Wed Dec 28, 2022 2:46 pm

Hi, Was browsing threads here before and i from what i saw it seems like other users were using the sparkfun OBDII UART devices with pcm hammer to read and write bin files.

so far I've been unable to get my OBDII UART to read with pcm hammer, even though it works with other apps(OBD doctor on my PC, Torque on my phone).

Curious what setting anyone else may be using with pcm hammer to get a read? which serial device setting to use in pcm hammer?

Everything other than the uart seems to be good. 14 volts, bench harnes is good (Works with (HPtuners, torque, other apps and software), my obdlink cable works to read/write...

would be great if i could get this device working, just because i already have a db9 connector for it hard wired into my truck for a previous project...

The one with the scantool stn chip should work with pcmhammer. It looks like you have the right one. What does the pcmhammer debug log say?

I test with one at every relevant change ...

Make sure it's firmware is at least v5.0.0.

Select whatever serial port it installed as.
Select Device Type of ObdLink or AllPro.

If you have unknown, damaged or unmanaged ports you can review/clean them with the following steps,

For Windows versions less then 10.
Find the "Command Prompt" shortcut and Right-Click on it,
Select: Run as administrator
If required, Enter: Password
At the command prompt type (or copy paste) the following two commands,
set DEVMGR_SHOW_NONPRESENT_DEVICES=1
devmgmt.msc

For Windows 10 and greater ...
In the Search box type
devmgmt
and select Device Manager.

When Device Manager opens,
Select: View
Select: Show hidden devices
. . In the Device Manager Tree view,
Expand: Ports (COM & LPT)
. . On any ports you want to remove,
Select: Right Click
Select: Uninstall
. . In the Confirm Device Uninstall dialog,
Un-Check: Delete the driver software for this device
Select: Ok

The next time you plug the device in, it will re-install ...

I personally Uninstall all virtual COM ports and just allow them to reinstall in the specific order I plug the devices back in ... That way I get what I want on the ports I want them on.

BTW, the OBD II UART defaults to 38400 baud ... PCM Hammer expects 115200.

Test (or change) with a terminal program like PuTTY.

To change the default, look up Programmable Parameter 0C in the ELM327 Data Sheet.

debug log:

[04:30:29:297] ElmDevice initialization starting.
[04:30:29:312] TX:
[04:30:30:530] TX: AT Z
[04:30:31:742]
[04:30:31:742] No device found on COM3
[04:30:31:742] Unable to initialize ObdLink or AllPro on COM3

Tried Uninstalling and reinstalling the hardware.
Firmware is 5.7.1 (latest)
Windows set baud rate for the serial port to 9600, so i changed that to 38400(just in windows). so clearly I do have something set wrong. not much time to play for now.
Tried again and still no dice.

Going to try again later tonight when I have more time to play, Going to try to figure out PuTTY.
Thanks for all the help so far.

PuTTY is simple ... The three red encircled settings are the only important ones,

Set the "Serial Line" to whatever COM port the device is installed as.
Set the "Speed" to 38400.

Select the Open button ...

If all is well (you may have to hit enter) you should get a prompt like,
PuTTY_Prompt.png

They call that the AT prompt ...

Type ATZ and hit enter, you should get back the ELM version.

If you do not, reset PuTTY and try with a different baud (Speed) rate.

Once you have a clear connection to the device ... Set the default baud to 115200 at the AT prompt, follow each with the enter key, you should get OK in response.
Example:
AT PP 0C SV 23
AT PP 0C ON

Restart device and test.

Leave Windows port settings alone, they need no change, they are basically ignored.

Thanks for the tutorial, my UART is working with pcm hammer now.

Going to keep playing around as time goes on, my device is v1.4b, that must be part of the difference but mine still seems to want to default back to 9600.
Either way, once I established the link with PuTTY and tried again it works just fine, so one way or another at least I'm off to the races.

Thanks again

Soooo, after having a little more time to play, and after the previous advice in this thread, I now understand a little more about these devices, I went and did something a little bold; I wired the WIG 09555 to a sparkfun Bluesmirf gold Bluetooth adapter.

And to my utter amazement it actually managed to read a pcm.

Like, at this point I'm really just happy that it worked but based on the log it seemed a little squirrely. So if there is a way to get a more reliable connection I'm open to suggestions.

Wanted to post my pcm hammer logs here just in anyone had any advice on other possible setting to change or play with on the chipset that may get me a more reliable read?
