Execute commads via remote API (tcp opton)

Currently we have exactly the the same problem. Everything else over API works but not execution of the commands. We have checked everything like permissions etc but I think this is something else that we can not really find what it is.

gchumbes, have you solved the problem and could you please post what was the problem?

Maybe Gurtam guys know how to solve this error: 4 issue while executing commands over API?

Thanks.

We are not trying to first Create a command, we are executing it without prior creating any command. Do we need to create it first?

Well, we are trying to execute a command like this:
http://sdk.wialonpro.com/ajax.html?svc=unit/exec_cmd&params={"itemId":3798,"commandName":"Fall_Down_Alarm","linkType":"tcp","param":"123456F1","timeout":20,"flags":0}&ssid=4003231d4766a13d733b1c8dba72e6e2

Can you please give me example that you know should work? As parameter you can write anything just give us an example.

It does not work!

Getting "error: 4" even while I am issuing command unit/update_command_definition

http://sdk.wialonpro.com/ajax.html?svc=unit/update_command_definition&params={"itemId":3798, "id":123, "callMode":"create", "n":"fall_alarm", "c":"custom_msg", "l":"tcp", "p":"123456F1", "a":"0xfffffffffffffff"}&ssid=3785df7e66b3a8fd14287bac7537415d

I didn't know what to write as id so I just typed 123. I don' know if this is needed during command creation?
