CC1352P: Generate tracking request whenever required in collector in TI 15.4 stack

Haricharan sarpatwar

Part Number: CC1352P

HI,

I am working on CC1352 devices with TI 15.4 stack sensor and collector examples.

I had two queries regarding Tracking and polling intervals.

1. I would like to make generate_tracking_request function in collector when ever i need to send a data message to particular sensor. Will this is possible? Presently collector is sending tracking message to one sensor in the list with one minute interval, which is expecting a tracking response from that sensor which will lead to power consumption in sensor. which i would like to reduce.

2. Can the polling interval in the sensor is increased or removed and with this implementation can the sensor able to receive message sent by collector.

1. What is generate_tracking_request function?
2. If you increase polling interval, it will slow sensor receiving message from collector. If you disable polling, sensor won't be able to receive message from collector.

Hi,
1. I Can able to send tracking request to sensors from collector for every one minute now i increased it to 5 minutes. I think this could not make much difference because our app expect response from each query collector asks other wise the sensor is out of range. There could be problem if sensor goes off in the mean while. Again alive status is on after sensor is on, so i can handle this.
2. where can i change polling interval in sensor to 5 minutes? There is a minimum(1 second) and maximum(10 seconds) polling interval in sensor. If i change 10 seconds to 5 minutes intervals then my sensor is restarting? what change can be done for this? My application has low power consumption requirement. If i increase polling interval, it will slow sensor receiving message from collector my application is OK with that.

correct me if i am wrong

You can change CONFIG_POLLING_INTERVAL in config.h to change polling rate. However, if you change it to 5 minutes, it means sensor only wake up every 5 minutes to receive data and it won’t be able to receive anything during sleeping.

hi,

If i change 10 seconds to 5 minutes intervals then my sensor is restarting?

No, sensor won’t restart because of such modification.

K I also tried on another hardware I found sensor is not restarting.

Thank you for your quick response
