Hi,

I have a couple of question regarding the maximum paring distance possible.

Please discuss the follow basic questions below.

1) Is there a way to increase paring distance by optimizing hello_sensor code, regardless of Hardware?

   I have implemented a routine that sets up the Tx power as 4dBm using the "blecm_setTxPowerInADV( )" on "hello_sensor_create( )"

   In addition to setting the parameter, CONST definition of the BLE_PROFILE_CFG in hello_sensor application,

   I wonder if there is any way to increase the paring distance or to stabilize the paring sequence on that application.

  

2) The pairing distance possible varies with commercially available mobile OS type and applications.

   What is major factor affecting the paring distance without hardware components such as build in antenna.

   If you are a specialist in that part of BLE software, could you send us information about it?
