Sensor Type 82 didn't respond to request on demand command

Hi, we configured a sensor type 82, got recently, as mode =2, to get process data and time domain data on demand. We follow the same sequence we developed last year following instructions from NCD that worked fine before, but for some reason we cannot get the waveform from this new sensor. Please see attached the exported flow in node-red and pictures of it. It seems when it received the request command, the sensor just reboot by itself, we have seen RUN message every time after sending command. We can read process data but not waveform data.
Please could you help us troubleshooting what else we can do.

Hi,

Can you share a processed sensor_data msg to confirm that it states the mode is 2?

Network communications can play tricks with comm delays so you might try reducing that delay time to 100ms.

Yes it is in mode 2, please see attached screenshot.
Actually we tried 100 ms-300ms same results. And we set the waiting time up to 3 seconds on the device waiting for the request command.

If the radio frequency is 2.4GHz, ensure that the payload length is set to 55 bytes.
The 2.4GHz band does not support larger packet sizes, which results in fewer samples being transmitted. the max sample per axis will be around 1024 in this case.
also set your sample duration to lowest for testing.

OK, thanks, we will give a try

Bhaskar, we did the changes (55 payload length, lower the sample rate to 3200, and sample time=50 ms), and it worked!
Thanks a lot!
