I have 2 devices connected with the module. Each one has an object with a different port. They should work separately, however, after a while with both devices enabled, one of them start getting sequence count numbers (like ACKs) totally random (even negative numbers) so the communication fails.

Also, if I duplicate the module locally and use each copy for each device it works perfectly. I guess there's some kind of interference.

Thank you for this module and keep working. Nice work!

Hey is it possible to do another NPM release for this package?

The one currently on npm failed to build on node 17 but the git one works just fine.

Hi @skokov3812!
I see that you are not very active in development of this project. Would be nce if you could allow automated releases using semantic-release and Circle CI when changes are made to the main branch. Another option to add me as contributor on NPM or transfer repository to me, or public organization at github.
I appreciate your investment in this project! Thanks

Had a crash happen while accepting bills. My program isn't too different from the one in the example, it's slightly modified.

hello,
new device https://innovative-technology.com/products/products-main/901-nv4000 is now available, with new commands and events. Is there some library update planned?

I tried some changes, but for this new device I have too much TIMEOUT responses while polling, and also device change status to DISABLED in some strange intervals, maybe because of timeouts.

Hi, command GET_ALL_LEVELS does not work well with NV200 (every other time). What can be done? Thanks

Hi,
When sending the SET_DENOMINATION_ROUTE command with the following parameters in protocol version 6, the error PARAMETER_OUT_OF_RANGE is returned

parameters send:
{route: 'payout', value: 2000, country_code: 'EUR'}

Does anyone know what can it be ?

Hi,

Using the SMART Hopper I noticed when I insert a coin, the poll command doesn't retrieve any event but checking the packet, the protocol do retrieve the VALUE_ADDED event. I guess it's pending to implement in the module.

Greetings and Great Job,
Iago Loureiro.

logs for reading note.
logs.txt

as mentioned in #13 issue

We are also having some issues with receiving “stacked” and “note_stored_in_payout” events. We occasionally see them, but most of the time, nothing comes in after the “credit_note” event.
Do you receive “stack” and “note_stored_in_payout” events?
We’ve been unable to correlate this behavior with anything.

I cant find anywhere some documentation in order to handle the nv9usb with a note float.
I would love to implement it but i cant find anything.

Somebody got any luck ?

So far i get this reply at polling:

If you call several commands or enable function more than once at the same time it will lead to poll cycles multiplying (multiple subscriptions to events). This is a huge problem cause it will multiply events also like CREDIT_NOTE, STACKED_NOTE, etc. Like this, if you use debug:

COM <- 7f00117ef582eff14bd18fdcfe15b71cd043a2eec145 POLL 162
COM <- 7f00117ef582eff14bd18fdcfe15b71cd043a2eec145 POLL 162
COM <- 7f00117ef582eff14bd18fdcfe15b71cd043a2eec145 POLL 162

I will create a pull request.

hi, i have smart hopper and when i set the comand : setup_request

some one can help me thanks

Hi, I am testing with nv11.
I ran the example, it says enabled 'OK' however the bezel does not light up to accept bills. I am able to run the Payout Last note with success and it dispenses but the Payout Amount function returns Command_NOT_KNOWN.

Any help will be great, thanks in advance.

I have implemented the software to monitor the NV9USB+, it seems to work perfectly,
Open and sync per your example, it was installed on windows 10 ( nodejs)
1 I restarted and after could work normally
2 if I shut it down, my code could not enable the device
3 if power is lost, my code could not enable the device.
==> so I have to use the C# sample application to open the connection to the device and enable it , and after I enable it via C# code, there would not be such a problem until the computer was shut down or power lost.

It seems the device could not be properly connected, after 2 and 3 conditions.

Does any one have such a problem?

I have a Smart hopper and everything seems to work, until I insert a coin.
Then i receive a crash in utils.js and I was able to track it to this piece of code: https://github.com/skokov3812/encrypted-smiley-secure-protocol/blob/master/src/utils.js#L376
Error is something like "out of bounds". Looking at chunk variable mine is:

Uint8Array(8) [
  223, 200,  0,  0,
    0,  66, 71, 78
]

Having: let count = chunk[1]; make next slices to go out of bounds, since there is clearly no 200 items into array.
I can see that 200, 0, 0, 0 is value of coin I insert (200 stotinki), and next is 66, 71, 78 which is BGN.
These values are not from 2 to 6 and from 6 to 9 like in: https://github.com/skokov3812/encrypted-smiley-secure-protocol/blob/master/src/utils.js#L380, but are offset by one i.e. from 1 to 5 and from 5 to 8.
Now the question is: is chunk wrong or there is something else what I miss?

Any idea about this error?

Hi, the example works fine till the polling. During the polling i get the following message

{
  success: true,
  status: 'OK',
  command: 'POLL',
  info: [
    {
      code: 198,
      name: 'PAYOUT_OUT_OF_SERVICE',
      description: 'This event is given if the payout goes out of service during operation. If this event is detected after a poll, the host can send the ENABLE PAYOUT DEVICE command to determine if the payout unit comes back into service.'
    }
  ]
}

and the nv9usb+ is not active (do not accept bill).

I tried to send the command ENABLE_PAYOUT_DEVICE without any success

hello,

is escrow functionality implemented? or do you plan to implement it?

as described here.

Hi, first of all thank you for this amazing project.

I have a bit of a problem: all the command return
{ success: false, status: 'KEY_NOT_SET', command: 'ENABLE', info: {} }

the hardware is an NV9USB and here the config of the lib:
let eSSP = new sspLib({ id: 0, debug: true, timeout: 50000, encryptAllCommand: true, fixedKey: '0123456701234567' });

Thank you for your time

I updated to the latest version and SET_DENOMINATION_ROUTE doesn't seem to work. The old version worked just fine.

Hi,

I detected a documentation error related to GET_DENOMINATION_ROUTE command. In theory it should get some args (I use {value: x, country_code: 'XXX') but that's not documented.

Greetings and great job,
Iago Loureiro.

Im experiencing some issues with this code on linux based systems.

At first, the randomPrime functions not always returns a prime number, that should be a problem?

Also in the debug mode, my routine always ends with a 232 error, as bellow:

hi, sorry to bother.

But whenver i try to insert a banknote the software crash. with no errors

Any idea ?

the hardware is an nv9usb+
