Hi
I am using two sets of different Eddystone beacons configured to transmit Eddystone UID data (namespace and instance id).
One set of beacons are off the shelf (OTS) beacons and other set we have developed using NRF52. While receiving the data we have observed that the data (namespace and instance id) from two beacons are getting mixed up, particularly the instance id of OTS beacon being received in the data packet of the beacon that we have developed.
For receiving we have used Raspberry pi based gateway with custom application to read and collect beacon data.
More info on different test that have done
1. We have tested using only the OTS beacons transmitting UID packets with different namespace and instance id, in this case all the data is received correctly. So we are assuming that the receivers are working properly.
2. While testing with only our beacons we have seen that the instance id configured for one beacon is seen in the data packet received for other beacon which actually has a different instance id.
3. While testing with OTS beacons and our beacons transmitting simultaneously we have seen that some of the data packets received for our beacons has the instance id of one of the OTS beacons. But the data packets for OTS beacons are received correctly.
Beacon details
Our beacons use NRF52832 with SDK 15.2.0 and softdevice S132. We have developed our application taking ble_app_eddystone example and made changes to suit our requirements.
The data is getting mixed up only when our beacons are used. All beacons are transmitting at an interval of 2 sec.
Can such an interference occur over the air with only a few beacons (around 10) in close proximity of the receiver? Can the transmission from the beacons be made more secure to avoid such interference?
At this moment we are unsure if this could be an issue on the beacon transmitter side or the receiver. Kindly let us know how we can address this issue.
Thanks
