S120 has very short range?

Question

Hi
We did a few tests with the S120 softdevice (example in the SDK 5.1). Most things are working as expected, but the range of the device is by far less than we reached with the S110 examples. 
 Devices could only be detected by the scan if they were in a distance of 5 meter or less. Do you have an explanation for this?

Hi Adrian, 
 In order to avoid spurious connections to devices, and to be able to work with limited interface, examples for S120 are configured to connect to devices only in a certain range. If you want to relax this, CONN_MNGR_TARGET_RSSI in conn_mngr_cnfg.h should be set to -127 instead of default of -60 provided in the example. 
 You will be able to establish connections with peripherals over longer distances with this. 
 In case you want to know further details about the configuration, I would encourage you to read the documentation . 
 Hope this helps! 
 Regards,
Krishna
