Command issue on KHD protocol
It's probably expecting HEX format.
@Anton, I converted the command AS9876*269C#00 to hex as 4153393837362A32363943233030 and sent it to the devices via the frontend. In the database, I received the response {"result":"2"}.
OK, great.
"Anton, I have not received the response to this command. Instead, I always receive {"result":"2"} in the database and reports. Can you help me understand why I am not receiving the correct response?"
Have you checked with your device vendor?
Yes, I have checked and tested this on other portals as well, and everything is fine. However, in Tracacr, command responses are not being received
What is the expected response? Have you checked the logs to see if the device is actually sending it?
@Anton, the some 1 or2 Teltonika devices are sending a response with the following data:
{"result":"Data Link: 1 GPRS: 1 Phone: 0 SIM: 0 OP: 42003 Signal: 5 NewSMS: 0 Roaming: 0 SMSFull: 0 LAC: 4338 Cell ID: 43013 NetType: 1 FwUpd:-65536"}
However, the KHD protocol is only showing this:
{"result":"2"}
Why would you compare Teltonika with KHD? Those are completely different protocols and almost definitely different response format.
I am not comparing Teltonika and KHD here, just giving an example. KHD has not provided any response.
Hello Team
We are using Command Result notification for our admin account to monitor device activities. It has been working fine with other protocols.
Today we tested a device using the KHD protocol, and we started receiving continuous Command Result events in few seconds even though we are not sending any command to the device.
The device keeps generating result events automatically, which is creating unnecessary notifications for the admin account.
Example:
No command sent from server
Device still generating command result
Notifications triggered repeatedly
We would like to:
Ignore command result events only for this specific KHD device
Keep Command Result notifications active for other devices
Is there a way to:
Filter commandResult event per device?
Or ignore result attribute only for this device?
Or disable command result event generation for KHD protocol?
Notification page screenshot for reference:
Looking forward to your guidance.
Thank you.
You can add a computed attribute and return null result to clear the attribute.
Dear team,I am facing some issues sending a command on the KHD protocol. I am sending this command:
AS9876*269#C#and received the following error: "Odd number of characters. - DecoderException (... < DataConverter:29 < BaseProtocol:110 < DeviceSession:66 < ...)". When I decoded this, I found it's a format issue. Can you please tell me the correct format or point out where I am mistaken?Thank you.
