SunTech ST-940 Support

Hi. Doubt. Does Traccar support the ST-940 device from SunTech ?. I think it's compatible with the ST-910 (which is supported), but I'm not sure.

It is supported, as far as I know.

Hi. I am testing an ST-940 device, and Traccar sends the following error (NumberFormatException):

2018-05-04 21:13:57 DEBUG: [B1BC1E94: 5011 < 201.130.59.148] HEX: 53543931303b456d657267656e63793b3930373531303138363b3535323b32303138303530343b32313a31343a30333b306666333465353336313b2b31392e3330313237363b2d3039392e3139303433333b3030302e3030303b3030302e30303b303b32383436323b36303b303b313b30323b3333343b30353b2d3234303b32303035313b3235353b303b3130300d

I decode the chain, and it is as follows:

ST910;Emergency;907510186;552;20180504;21:14:03;0ff34e5361;+19.301276;-099.190433;000.000;000.00;0;28462;60;0;1;02;334;05;-240;20051;255;0;100

¿Pueden, por favor, ayudarme?, ¿Cual sera el problema?.

You probably need to configure protocol type:

https://github.com/traccar/traccar/blob/master/src/org/traccar/protocol/SuntechProtocolDecoder.java#L44

Hi.

Sorry. I did not understand well. Do I have to modify the source code ?, Or any configuration file with extension .protocolType?

Configuration suntech.protocolType parameter.

O. K., thanks.

Is that a configuration file?, What path is it in?, What is its structure?, How can I modify the ST-910 configuration to make it compatible with the ST-940?

It's a parameter in Traccar configuration file.

Hi.

I do not see that parameter in the configuration files. I guess I have to add it, what is its structure?, What should it contain?

You have to add it. I think the value should be 1, but you need to check with device vendor.

Hi.

I add the parameter, restart the services, and keep sending the same error:

I've just tested it on latest code and it works fine for me.

Hi.

I download the latest code from the GitHub repository, try compiling with NetBeans 8.2, its send the following result, and do not create any JARs:

Failed tests:   testDecode(org.traccar.protocol.SuntechProtocolDecoderTest): latitude expected:<37.47877> but was:<126.88969>

Tests run: 323, Failures: 1, Errors: 0, Skipped: 8

You can disable test cases if they are failing for you.

Hi.

It Keep sending the same error. I try another server (to rule out a configuration problem), and send a similar error:
