Custom commands JM-VL01 device

Cristian 2 years ago

Good afternoon everyone, I am testing a JM-VL01 device, If I consult the list of supported devices, the VL01 appears. But I have the following problem: when I send a custom command like for example STATUS# I get this response:

2024-01-03 15:43:07 STATU command result Unrecognized!

Apparently it cuts off part of the command sent

Does anyone else have or had this problem?

point the device to demo.traccar.org and it throws the same error when sending a custom command

Just to close the subject, I have found the solution.
For the case of the JM-VL01 the custom commands should be sent as follows:

command format according to the manufacturer
VERSION#
for Traccar should be sent like this:
VERSION,#

Another example would be this:

command format according to the manufacturer
STATUS#
for Traccar should be sent like this:
STATUS,#

In summary I was able to determine that a comma should be added after each instruction in the command, except after the #.
