AD2pHat won't talk to Vista panel

[4832M5]

Hello.

Have a AD2pHAT that will talk with Pi3B but no messages to/from Vista panel

>telnet 127.0.0.1 10000

!Sending.....done
```
Several forum message indicate that should see the familiar messages such as "****DISARMED**** Ready to Arm" or whatever. Further tried sending some arm key sequences via Screen and Telnet. Got no response as seen from other Alpha panels on alarm system. The last !Sending.....done above is such an attempt

System information
Vista-21iPLTE running firmware 4.1.16
*191 set to [1][0], address 18 enabled, (have Alpha keypads on 16 & 17)
Pi3b running Buster Lite, manual build from AD wiki.
comm via serial0 (ttyAMA0)
LED on A2DpHat is blinking at about 2 to 3 times per second.
NOTE the AD2pHAT came loaded with beta software V2.2a.8.9b-306


Web app always has keyboard in "Please wait...loading"

thanks for any help.

Update:
Telnet to device - get normal alarm status. Can send disarm cmds, they are received by Vista alarm (other panels respond).

Keyboard screen just sits in "waiting...."
All other screens/tabs in webapp appear to work as expected.

I missed this did you get this sorted?

I'm having a similar issue but what I've noticed is that ser2sock is actually crashing when I have the home assistant (HA) integration enabled and the webapp service running. I've also noticed that when I run ser2sock without dameonizing it and have the webapp service stopped on the pi HA is able to access ser2sock without crashing it... I'm happy to roubleshoot further but I'm not too sure what to check next.

[mathewss]

I think the most common cause of this is confusion in the webapp setup.

The default settings for webapp configure ser2sock to share the AD2 then for the main connection it sets the webapp to connect to ser2sock for everything. If two processes such as ser2sock and the webapp both try to access /dev/ttyAMA0 or /dev/ttyUSB0 etc they will have crazy results.

Please confirm the webapp is configured to connect to localhost on port 10000 and that it shares the AD2* to other systems. Then you can have other systems connect to port 10000 on the Pi's IP address.

Thanks! Running through the setup wizard again and changing it from serial to network did the trick!

I'm going to continue this thread because I think I'm having the same problem (or similar) and I'm not understanding how to resolve it.

Setup:
Pi3B with AD2pHat running latest (non-dev) flashed image and latest firmware as of 10/26/20
AD2pHAT is running off of Pi power
wired LAN connection to router
Vista 20p alarm system with wired and wireless zones
Pi4B running HomeAssistant (also most current master image)

Since switching over to the HomeAssistant integration for AlarmDecoder, now AD will not work for more than a few hours before the interface basically freezes up. It works fine after a restart, but after some period of time (hours), I can no longer communicate with the alarm system. It will not refresh or communicate via HA.

The AD web app will load, but it never shows a status on the keypad page. If you try "Test Device" on the Diagnostics page, it gives various errors. (It opens the device, but says test timed out or can't connect or some other error, sorry I don't remember because it seems different every time. Sometimes when I test, it sends lots of random false alerts via Pushover, like fire alerts.) It says Firmware Update is Available, but on the firmware page it doesn't know what my current firmware is. (It is 2.2a.8.8, which shows up fine after a restart).

The light on the AD2pHAT blinks twice, pauses, blinks twice.

I can log into the Pi3 with ssh, but when I try to run "screen /dev/ttyAMA0 115200" it gives a blank screen with a cursor and will not respond to any key input. I've never used "screen" before, so I'm not sure if that's what it's supposed to do, but I can't get it to respond to anything other than kill the screen. Screen behaves the same way after a fresh restart, which makes me think I don't know how to use it.

I suspect this is a similar problem referenced in this post (multiple things trying to access the AD2). But I'm not sure how to solve it. My setup wizard is already set to network. Thanks so much for your help, and please let me know if there are any other troubleshooting steps I can take.

Well, now it doesn’t work at all. I’m worried my AD2pHAT died somehow. It never connects to and shows the alarm display in webapp, and testing the device still opens the device, but times out on the other three checks. It shows up as ttyAMA0, but I haven’t been able to telnet to it. (Always a blank screen). The LED blinks continuously. I have tried to reflash the SD card and start from scratch, and have tried it on a Pi Zero as well as the Pi 3B, same result. What else can I try to troubleshoot it?

Thanks.

[mathewss]

I think you spent plenty of time and it should just work so I want to assume it is a bad board. I will send you an email so I can collect your info and send you a replacement tomorrow.

The only other way to test further is to have a TTL -> USB Serial adapter of some type like I use to test a unit with my PC at my desk. In effect it turns an AD2pHAT into an AD2USB.

That’s awesome! Thanks for the terrific support.
