Re: How to get Unit Last update date and time

Hello!

The requests events/load and events/get are used to get history events (trips, sensors, ignition , fuel thefts/fillings/consumption) which already registered in system
More - https://forum.gurtam.com/viewtopic.php? … 16#p186716

If you need to get current data, when unit is running online, you need to get use the following requests
https://sdk.wialon.com/wiki/en/sidebar/ … date_units - add units to session and specify event's detector
https://sdk.wialon.com/wiki/en/sidebar/ … ck_updates - execute request periodically to get data
See my previous answer - https://forum.gurtam.com/viewtopic.php? … 05#p183805

Re: How to get Unit Last update date and time

Hello!

When you execute command you need to pass the same parameters which original command has, like link type, commandName and etc.

In your example,
"n": "start engine" - commandName
"l": "" - link type (empty value means 'Auto')
"p": "Juste un exemple" - specified parameters

So you need to execute request unit/exec_cmd with the following parameters

"params":{"itemId":11489,"commandName":"start engine","linkType":"","param":"Juste un exemple","timeout":1,"flags":0}

Re: How to get Unit Last update date and time

Hi!

The device send this response to your command as I see on your screenshot, because there is not correct parameter 'Juste un exemple' for command. You need to send command (create command before for unit) with correct parameter for certain command. Please look to device's manual or request to manufacturer which parameters are correct for this command type.
Maybe here on forum - https://forum.gurtam.com/viewforum.php?id=18 you can find helpful information

Re: How to get Unit Last update date and time

Hi,

Thanks for the reply now it's working for us

I just want to know how I can display Map on the report please check below API request

{svc=report/export_result, params={"format":2,"pageOrientation":"portrait","pageSize":"a4","pageWidth":0,"coding":"utf8","delimiter":"semicolon","headings":0,"compress":0,"attachMap":1,"extendBounds":0,"hideMapBasis":0,"outputFileName":"eabdalmnem_30-04-2021"}, sid=d628a7f4e54b4cb31c928154b234cbb8}

I had reviewed with hideMapBasis hide map layer: 0 - no, 1 - yes

"extendBounds":0
"hideMapBasis":1

"extendBounds":1
"hideMapBasis":1

"extendBounds":1
"hideMapBasis":0

extendBounds=0
hideMapBasis=0

Please find both files different only is right of the screenshot with map and left is without map.

Re: How to get Unit Last update date and time

Hello

I need your 2 bits of help

1. Above request how to display Map background on the report

2. How to get sensor engine operation value in the check_updates API

From search_item API we got all sens value check_updates API

"sens": {
"1": {
"id": 1,
"n": "حالة المحرك",
"t": "engine operation",
"d": "",
"m": "On/Off",
"p": "adc1",
"f": 0,
"c": "{\"act\":0,\"appear_in_popup\":true,\"ci\":{},\"mu\":0,\"pos\":1,\"show_time\":false,\"timeout\":0,\"uct\":0,\"unbound_code\":\"\",\"validate_driver_unbound\":0,\"consumption\":2}",

"vt": 1,
"vs": 0,
"tbl": []
}

I am looking for same value from update_unit API how i can get, i do get but I got a second sensor not first

svc=events/update_units&params={"mode":"add","units":[{"id":11489,"detect":{"sensors":0}}]}&sid=c0816af7dfa8862ae026cf4a1499f2d8

svc=events/check_updates&params={"detalization":3}&sid=9e0f2c649220ff65229c68a56de69f3e

"11489": [
{
"sensors": {
"2": {
"from": {

"y": 24.7718658447,

Re: How to get Unit Last update date and time

Hello!

1. If you need to attach map to the exported PDF file, you need to pass parameter "attachMap":1, "hideMapBasis":0

"hideMapBasis":1 means tracks and markers are shown on the blank background
"extendBounds":1 means option Squeeze in all graphics

For example, parameters for request report/export_result

{"compress":0,"attachMap":1,"hideGoogleLinks":0,"extendBounds":0,"hideMapBasis":0,"pageOrientation":"landscap","pageSize":"a4","pageWidth":"0","coding":"utf8","delimiter":"semicolon","headings":1,"outputFileName":"Volvo_awesome_!gtest_Eco_driving_03-05-2021_14-38-20","format":2}

2.The sensor engine operation is not included to 'sensors' event detector. To get data from this sensor type you need to get event type 'ignition'
So instead detector 'sensors' in request events/update_units just add detect 'ignition' - "detect":{"ignition":0} or "detect":{"ignition":1} as you already know the sensor id.

Re: How to get Unit Last update date and time

Hello Thanks for the reply it's working fine

to add the unit to get the update we set this API as per your suggestion and its working fine when we have small[20] set of units

but when I have 500 units then we get error

1.{"id":11489,"detect":{"ignition":0,"sensors":0}}
2.{"id":11499,"detect":{"ignition":0,"sensors":0}}
.
.
.
500 .{"id":11989,"detect":{"ignition":0,"sensors":0}}

<head>
<title>414 Request-URI Too Large</title>

Re: How to get Unit Last update date and time

Hello!

First make sure that you perform POST request. There is basic limit to length of URL.
Also I think to monitor at one time all 500 units is quite complicated, even just to get information about all 500 units on one screen (specially mobile screen). So if in your app the units visualization are divided on several blocks (parts, pages) you can request to add units into session sequentially, if necessary.

Re: How to get Unit Last update date and time

Hi!

You can use the several ways :

1) Just get the last message from request search item(s) with flag = 1024, last message and position
Flags - https://sdk.wialon.com/wiki/en/sidebar/ … ormat/unit
Search item(items) - https://sdk.wialon.com/wiki/en/sidebar/ … les/search

2) To get current event (trip or stop) via requests events/update_units & events/check_updates (not events/load, it's used only to get history data) - https://sdk.wialon.com/wiki/en/sidebar/ … ck_updates
https://sdk.wialon.com/wiki/en/sidebar/ … date_units
Here more useful information (webinar) how to work with these requests (methods event) - https://www.youtube.com/watch?v=nUtNS5Al5wo

Re: How to get Unit Last update date and time

Hi!

yes, you can get current trip via events requests - events/check_updates
where in JSON response in 'to' you will get the last coordinates

"to": {
            "t":<uint>,    /* time (UNIX-time) */
            "y":<double>,    /* latitude */
            "x":<double>    /* longitude */
        }

For example

1. Add unit to session - https://sdk.wialon.com/wiki/en/sidebar/ … date_units
events/update_units

params
{"mode":"add","units":[{"id":21728414,"detect":{"trips":0,"sensors":0}}]}

2. Execute request check_updates
events/check_updates

params {"detalization":3}

In response we get current trip which starts at 1624876649 Jun 28 2021 13:37:29 GMT+03
"state": 1 means that the trip is going ( /* state: 0 - parking, 1 - trip, 2 - stop */ )
the last message and location in parameter 'to'

"trips": {
                "from": {
                    "t": 1624876649,
                    "y": 53.4268836975,
                    "x": 27.9888801575
                },
                "to": {
                    "t": 1624877580,
                    "y": 53.4268836975,
                    "x": 27.9888801575
                },
                "m": 1624877580,
                "f": 2,
                "state": 1,
                "max_speed": 23,
                "curr_speed": 23,
                "avg_speed": 0,
                "distance": 0,
                "odometer": 2147483648,
                "course": 90,
                "altitude": 90,
                "pos_flags": 0
            }

3 Again execute events/check_updates and get the new data:
updated last position and time in parameter 'to'
the "state": 1 , so the trip is still going

 "trips": {
                "from": {
                    "t": 1624876649,
                    "y": 53.4268836975,
                    "x": 27.9888801575
                },
                "to": {
                    "t": 1624877925,
                    "y": 51.4268836975,
                    "x": 27.9888801575
                },
                "m": 1624877925,
                "f": 2,
                "state": 1,
                "max_speed": 120,
                "curr_speed": 120,
                "avg_speed": 628,
                "distance": 222553,
                "odometer": 2147483648,
                "course": 90,
                "altitude": 90,
                "pos_flags": 0
            }

Hello!

In this case to get all messages from event you can pass digitalization flags 16 plus 8 , for example total "detalization":25

The response

"msgs":[{"tm":1454479860,"x":38.4273986816,"y":65.6319351196,"z":30,"c":18,"m":0,"s":10}...], // all messages
