I'm getting error: 7 what I'm doing wrong?

Hello!

The error 7 due to request search_item means that is not access right (not enough access right) or not correct item id.
Please check the access rights for user by which you login - https://sdk.wialon.com/wiki/en/sidebar/ … cess_flags
You can execute searh_item with flag =1 and check the "uacl" - current user access level for unit

Also check the id - you can execute request search_items to find unit by name, and get the id in response.

Hi!

Depend on your task (your app logic) you can get last position from requests search_item(s) , including flag value = 1024, last position
it's useful when you, for example, build the table (list) of all units where one of column is last position, but in this case to update date it needs to execute again this request
The other way is execute request avl_evts periodically, for example every 2-3 sec - https://sdk.wialon.com/wiki/en/sidebar/ … s/avl_evts
And catch the new messages from unit
This way is good that you can get always the update data and due to constitutionally execution it allows to hold session,
The session lasts during 5 minutes after last request to server. If there is no executing any request after 5 minutes, the session will be interrupted.

Hi Carlos!

You are right, you need to add unit id and specify flag = 1024 (in dec) to get unit's position

Hello,
I want to know the reason why I get message error ACCESS DENIED or error:7 when I try to login using "url/wialon/ajax.html?svc=core/login&params={user:"username",password:"password"}" OR "wialon.core.Session.getInstance().login()"

Thank you in advance!
