    High supply current during scanning

    bartels_2365481

      I use the 20737 in central mode and see during the scan period that it draws a hefty 30mA, way too high for battery operation. Oddly during a connection with data exchange the current is much lower. Why?

      The receiver should also be enabled during that period, and thus operates comparable to scanning.

       

      Is there anything that I could do to reduce the current during the scanning period?

      Currently I use 150ms window every 3 seconds. To be clear: 30mA flows during 150 ms.

       

      I never expected that scanning would require more battery power than advertsing, so something must be very wrong. But what?
