LAUNCHXL-CC26X2R1: SYS_SET_TIME Return Code?

Part Number: LAUNCHXL-CC26X2R1

Hello,

I am setting the SYS_SET_TIME as follows:

fe0b2110 00000000 0b 33 37 08 10 e607 cc

- UTC time is all zero, using the values for minute, hour etc. The year I changed MSB/LSB from 07e6 (2002) to e607

Answer is supposed to be "fe016110 + FCS". However, I am getting: fe03600002211050.

Even a SYS_GET_TIME does return: fe03600002211151 (which is fixed for each call, not changing).

Thanks,

Robert

Hi Robert,

You are most likely receiving a MT_RPC_ERR_COMMAND_ID status in MT_SysCommandProcessing resulting in due to FEATURE_UTC_TIME not being defined in the ZNP project.

Thanks. How can I now set the time? :-) I am using this Zigbee2Mqtt FW. Any chance to set the time? My goal is to have a correct timestamp in the messages received from my sensors (set by the ZC once message was received).

Regards,

Robert

You would need to rebuild the ZNP project to enable these settings. You can consult the Zigbee2MQTT forum and/or develop your own host application solution. The APIs do not change over-the-air packet structure, simply initialize the SimpleLink OSAL UTC which you can read from at any time.

Understand. Guess this is too much trouble :) So bottom line with this firmware I am using, I cannot set/read the time as this feature is not enabled. What about those timestamp in AF_INCOMING_MSG:

fe1b448100000600009e010100cc00 9d460a00 000718540a00001001009e1d88

The red part is the 4 byte time stamp (000a469d) - 673437? Did I get this right? Is this the seconds since 1970? This stamp is set by the sensor (when sending) or by the ZC when receiving? I am just running a script which is sending/receiving from a TCP socket (which gets converted to the serial on the board). Anything I can send/set to get a correct timestamp into the messages I am receiving?

Thanks,

Robert

This is the MAC Timer2 timestamp at Rx, which is in in internal MAC timer units (RAT ticks). https://e2e.ti.com/f/1/t/850850

Only the local device adheres to this timestamp, and it will not affect transmissions.

Thanks Ryan. Understand. I will just set the time when I will receive the messages. The idea was to get the time once the message is received by the ZC (based on the ZC time set, system time) and once I receive the messages via the serial interface (in my case via the TCP socket). This is anyway the same time as I am constantly reading from the socket checking for incoming messages.

Thanks,

Robert
