Al messages from specific time

Good afternoon!

With flags you can specify which messages type you need to load. Flags mask used to specify which bits (flags) use in flags values and the final value of flags is calculated with bitwise AND between flags and mask. For example, you need only messages with position data so use flag 0x01 and mask  0xFF01. It's possible to mixin different flags with bitwise OR between their values.

hello, I neet this please..thanks

Hi!

We are now seeing data, however all the events are coming back with a message type of “ud” whereas the document stats this should be “evt” for events. Why is this? What does “ud” mean?

thanks

thanks Hamed,

client tested and informs me:

From that link we have “ud” is under “Message with data”. We are looking for data in regards to Events and our attempts to follow the information in the below section, from your link, gives results in tp=ud which is for “Message with data”. We do use this to obtain the GPS information we need. However we also need event/violations. We have followed the below and its not giving us the event data. What should the flag digit be? We have been using 1 = violation (see the link below).

Hi Pablo,

there is not correct flags and flags mask  - "flags":1 is for messages (data) from device, that is why type "tp":"ud",        /* message type (ud - message with data) */

You need to apply the following flag and mask  - "flags":1537 = event type (1536) + violations (1) ,
"flagsMask":65281 - the value used to define necessary flags after mask (0x601 & 0xFF01 = 0x601)

Please note such events messages are get if before they were registered as violation event in Wialon manually or via notification (action - Register as violation )

locationGPS , do you mean ETA service between two points?

It is scientifically proved that when you wait too much for answers about technical support, it is not just the Clients get bored and contract other companies...it affects directly to the sense of expression...
