PGN127507 test data

[nmbath]

PGN127507 is in canboat, with recent modification from single packet to fast packet definition (canboat/canboat#243). There is an issue in SignalK to add support for the PGN (SignalK/n2k-signalk#219).

I have noticed that there is no test PGN definition in canboatjs. The following I hope supplies a test module for the PGN.

module.exports = [{
"expected": {"timestamp":"2016-02-28T19:57:02.829Z","prio":6,"src":129,"dst":255,"pgn":127507,"description":"Charger Status","fields":{"Instance":114,"Battery Instance":6,"Operating State":"Disabled","Charge Mode":"Standalone","Charger Enable/Disable":"Off"}},
"input": "2016-02-28T19:57:02.829Z,6,127507,129,255,6,72,06,08,fc,ff,ff"
}]

When run in the test harness it passes..

✓ to pgn 127507 (Charger Status) converts

Please however note, the can message used in both the above test and the Actisense screen shot does not deliver a correct output when parsed through candumpanalyzerjs.

cat PGN127507-single.txt
can0 19F21381 [8] A0 06 71 00 08 FC FF FF

cat PGN127507-single.txt | ./canboat/canboatjs/bin/candumpanalyzerjs
{"canId":435295105,"prio":6,"src":129,"dst":255,"pgn":127507,"timestamp":"2021-08-26T18:10:07.989Z","fields":{"Instance":160,"Battery Instance":6,"Operating State":"Bulk","Charge Mode":7,"Charger Enable/Disable":"Off","Equalization Pending":"Off","Reserved1":"0","Equalization Time Remaining":64520},"description":"Charger Status"}

Note the incorrect INSTANCE and values on all subsequent fields. This reflects the issue reported here SignalK/n2k-signalk#219 and #161. As noted in issue 161, I can get correct behaviour by changing the pgns.json file and defining the length as 9. The problem of parsing fast packets with 6 or less fields seems to be a canboatjs issues and not n2k-signalk.
