properties: [{id: 8}] results in Error: ERR_TIMEOUT

• [x ] Bug Report

Expected Behaviour (Bug Report)

• using the readPropertyMultiple command with the properties: [{id: 8}] results in Error: ERR_TIMEOUT, although it should support 8 for all properties

• tried increasing the adpuTimeout: 9000 but still got the same result Error: ERR_TIMEOUT

• the code does work if called with singular properties like properties: [{id: 77},{id: 28},{id: 85},{id: 111}]

• in the last working version from the original library node-bacstack the results are as expected ie: with properties: [{id: 8}] we get the correct value object.

• my sample code

//setup the BACnet comms
const bacnet = require('node-bacnet');
const client = new bacnet({
  port: 47808,                          // Use BAC0 as communication port
  interface: '192.168.222.84',          // Listen on a specific interface
  broadcastAddress: '192.168.222.255',  // Use the subnet broadcast address
  adpuTimeout: 6000                     // Wait twice as long for response
});


// get what we want to read/write
const requestArray = [
  {objectId: {type: 8, instance: 1010220}, properties: [{id: 8}]}    //this results in ERR_TIMEOUT
  //{objectId: {type: 8, instance: 1010220}, properties: [{id: 77},{id: 28},{id: 85},{id: 111}]} //this works
];

// now send the request
client.readPropertyMultiple('192.168.222.222', requestArray, (err, object) => {
  console.log('Returned obj. = ', JSON.stringify(object,null,2));
  console.log('ERRORS if any or NULL :: ', err);
  // IMP close the open listening socket
  client.close();
});

[Apollon77]

Could you please attach a debug log from both libraries (the "old" one and this one)?

[aniston]

@Apollon77 I have never done a debug log before :(

• any advice how to get one done ?

or do you mean this text from the console ?

Returned obj. =  undefined
ERRORS if any or NULL ::  Error: ERR_TIMEOUT
    at Timeout._onTimeout (D:\node-bacstack\node_modules\node-bacnet\lib\client.js:158:16)
    at listOnTimeout (internal/timers.js:554:17)
    at processTimers (internal/timers.js:497:7)

[Apollon77]

call your script like

DEBUG=* node myscript.js

Should works for both libs

[aniston]

@Apollon77 , am on windoze , going thru the debug docs and found that I had to use that DEBUG=* method differently , namely set DEBUG=* & node app.js

• here is output from the node-bacnet lib

• for the "old" lib i do not get any DEBUG output ! only the correct JSON Object.

[Apollon77]

Interestingly also the old one shpuld work with debug ... https://github.com/fh1ch/node-bacstack/blob/master/FAQ.md#what-is-the-easiest-way-to-debug-failing-operations

[aniston]

hmmn, strange it does not work on the old one, tried both as per example fromt he FAQ link and the * method too.
set DEBUG=bacstack & node rpm_8_1010220.js
set DEBUG=* & node rpm_8_1010220.js
but no DEBUG messages , just the clean JSON object.

[Apollon77]

hm ... would be very intersting to see the "old" library on which messages are sent and such :-)

[aniston]

some more info:
I set up a Linux Debian 10 VM and installed both libs , still no DEBUG info from the old lib, tried combinations of the export env like
export DEBUG=bacstack and then DEBUG=* node app.js or node app.js
export DEBUG=* and then DEBUG=* node app.js or node app.js

I still do not get any debug output , just the correct resulting object, npm module debug look installed correctly given that i get DEBUG info on the current node-bacnet lib.

PS: the OP problem persists under Linux as well.

[Apollon77]

how you installed the old one? Directly from github? or how?

[aniston]

I installed the old one via npm with npm install --save bacstack
The installed versions are :

npm ls --depth=0
/root
├── [email protected]
└── [email protected]

[aniston]

I'm wondering if no one has found this problem before ? are you able to do a correct read PROP_ALL with properties: [{id: 8}] on a DEVICE object , while generally that is where it would be used.

[Apollon77]

It could be that the latest npm version of the old lib never had debug and only the github version has. Maybe install from github?

[aniston]

ok installed from GitHub, but still no DEBUG messages.

So after removing the default npm bacstack lib I did this to install directly from GitHub npm install fh1ch/node-bacstack.git
Sadly still no DEBUG messages !

and..

npm ls --depth=0

I am attaching the wireshark capture files of the BACnet protocol , they are captured as per the respective library names.
node-bacnet.txt
node-bacstack.txt
you will need to rename the extension with .pcapng else i could not attach them here.

[PJBCoetzer]

Hi @aniston, were you able to resolve this issue? I'm also facing the problem getting a ERR_TIMEOUT but unable to get the framework to run/get data from the BacNet network. I'm running on a edge micro pc running Debian 9 with Node 14 running. Can ping the host, but not getting any data though.
