The temperature sensor/collector demo example don't work

idan_aviad — Thu, 31 Jan 2019 15:07:04 GMT

Hi to all,
I'm trying to run the temperature sensor/collector demo example provided by NXP on 2 QN908XCDK boards/platforms.

I using IAR IDE.

Sometime a connection is established between the two devices, but in most times, no connection is establish.

I’m using a terminal connected to the collector device and I can see it is scanning, but still, in most cases no connection is established when I press the sensor device ‘WAKESW’ button and start advertising (‘CONNLED’ is red).

The boards are located few centimeters apart.

It is very frustrating….

Any help would be very appreciated.

Kind regards,
Idan Aviad

Hello,

Which SDK version are you using? Could you please help me with the tag of the SDK downloaded and the Bluetooth Stack version available in the documentation of the QN9080? Also, are you using a development kit ? If you do, which version are you using? Is it the 1.2 or the 1.3?

Did you check and follow all the instructions available in the BLE Demo Applications User's Guide?

Regards

Estephania

Hello,

Could you please try in the temperature_collector.c changing the following in the BleApp_Start(void)?

App_StartScanning(&gScanParams, BleApp_ScanningCallback, FALSE);
‍

Hi,

Thank a lot. I did the change as you recommended and it solved the problem. Connection is now established every time.

Do you have any idea, why it does not work with the advertising filtering enabled?

Is it an issue that may inflict on any future design (using this BLE device)?

and again...Thanks!
