how to improve the success rate of scanning ibeacon stations ?

[lou0908]

hi , now I am using nrf52832 base on the sdk 14 to develop our location system, the ibeacon around my nrf52832 circuit board will advertise every 500ms, and the parameters of scaning of our boards is shown as below:

   m_scan_params.active = 0;
  m_scan_params.interval = 5000;
  m_scan_params.window = 550;
  m_scan_params.timeout = 0;

I  found that ibeacon stations will advertise in three channels every 500ms, so the scan widows is set to 550ms  in my application, now I encounters the problem is that 5 ibeacon stations exist and my boards can only scan the 2~3 of them every scan widows.

how can I improve the success rate? is there fix channel scan definition of SDK?

look forward to your help, thank you

You are not writing what kind of environment you are operating in, maybe there is interference from Wifi? Have you tried moving the beacons closer to your board and/or do you see the same if you are using a nRF5-DK as a scanner?

thank you very much, I test my devices in our company's lab, there are so many wifi routers around my devices, and my devices will operate in the same environment at last, is there a solution to improve the problem? such as fix channel scan technology. can be solve it?

Increasing the output power or increase scan window are the two options you have.
