Read wrong ID sometimes

[0siata]

Hi there,

      We use nRF52832 to design a reader and use nRF52810 to design a tag. We put hundreds of tags together. Each tag transmits his ID every 5 seconds. 

A reader receives the tag's IDs all the time. Sometimes (very rare), the reader reads some extra IDs which are not the ones of the tags, i.e. the IDs are not registered.

We checked our code many many times. Is it possible that the problem is in hardware?

      Thanks

Hi,

I presume you are using a BLE softdevice to scan for peripheral devices that are advertising here? 

The advertisement packet contains a 24bit CRC, so it is slightly unlikely that an advertisement packet with errors will pass, but it is possible.

Is it possible that you may be picking up advertisement packets from beacons that are not yours?
