Hi,

There is a bug in the Smart Devices App. The night mode is deactivated properly but the App doesn't show it correct. We think that this problem was solved in the last version, please try to install again the Smart Devices App.

About second question, you can disable RSSI feature through the App. Or it will disable automatically if the node detects that callback server isn't installed. In that case, the node will send start1, start2, rssi up to 9 times and services frames, if no downlink, the node will be reset and will send the same frames than above, if no downlink again, the node will deactivate the RSSI feature.

Hi,

we have again the phenomen that all sensors are trapped in the following kind of "calibration loop" after a manual reset via magnet
(we use firmware v3.0.2, the sensors are surface-mounted and we currently have a temperature of 28 - 29 deg Celsius at the mounting positions):

START1 frame
DOWNLINK frame
(DOWNLINK frame)
START2 frame
Several RSSI frames
SERVICE frame
DOWNLINK frame
(DOWNLINK frame)

This loop is periodically repeated by all sensors since nearly 2 days, i.e. definitely more than 9 times which you have described in your last reply.
Hence, again my question:
What can be done to stop the loop and bring the sensors into the operational mode ?

Kind regards

Hi,

It is a very weird issue. Please share with us some screenshots of the Smart Devices App were we can see the firmware version installed in the node. Also please send us the frames send by the node.

Also please try to install the firmware v3.0.2 again.

Regards

Hi,

meanwhile all sensors have returned to their nominal mode after ca. 2 days and now send Keepalive packages again.
I think, it doesn't make much sense to reinstall Firmware version v3.0.2 because we are quite that this the firmware currently installed on the sensors.

Kind regards,
Klemens

Hi,

We are having issues with the parking sensors at daytime when the night mode is enabled, these issues are related to detecting the occupancy. For example: We are testing 6 sensors, all of them with the same configuration, then after parking the vehicle some sensors take up to 5 minutes, another sensors up to 3 minutes and the others between 20 to 60 seconds.

After many testings trying to troubleshoot the issue we realized that disabling night mode all of the sensors work in the cycle of 60 seconds to detect occupancy as per the configuration.

This is the configuration all sensors have:

Time Settings:

Sleep time: 1m

Keep-Alive: 0.5h

Night Mode

Duration: 6h

Start hour: 0h

Sleep time: 5m

Keep-Alive: 3h


Extra Configuration:

Sensor treshold: 75

Daily frame: marked

RSSI Feature: disabled


By the way, all sensors firmware are up to date which is V3.0.2 US.

We have solved the issue of detecting occupancy, but we need to come with the solution enabling night mode for the battery life purpose.

Could you please, HELP!


Thanks.

Hi,

When you are using the night mode, you have a sleep time (in your case 5 minutes) more bigger than normal mode (in your case 1 minute).

The sensor update the status in 5 minutes cycles. If one slot is occupied 3 minutes before the node check your own status, this node send the data in 3 minutes, if slot is occupied 1 minute before check your own status, the node send the data in one minute.

You have a period time where the status could change, but the node will not send the new status until wake up of sleep time period. If the status have not changed, the node will not send data.

Hi,

Thanks for your prompt reply.

As I said, I'm testing the sensors at Daytime, so if night time is enabled there should not be any cycle of 3 or 5 minutes. The daytime is set to 1 minute, then for all sensors the cycle shouldn't be longer than 60 seconds to change status.

By the way the night mode time starts at 0H, from my understanding is starting from midnight, is that correct?

If that is correct, why is changing the status around 3 to 5 minutes while testing at daytime?

Yes, your night mode start at 0h (midnight).

If the status node not change, the node not send data. If you have any cycle without status change, it will can be that the node not detect the change and the change is detected in the next cycle.

We not recommend change the threshold, but you can test with other values. May be your real application work better with other threshold values and other parameters. You need do the test and get your own better parameters.

Hi,

I did not understand this part from your reply:

"If you have any cycle without status change, it will can be that the node not detect the change and the change is detected in the next cycle"

Could you please explain clearly.


Thanks!

Hi,

It is possible that the node can not detect the car in any cycle but the node will detect in the next cycle. When the node change the status, it will send the data with the new status.

Regards,
