S120 has very short range

[Amit Varshney]

Hello, I'm working on nrf51822 with SDK9.0. I have two modules, one is working as a peripheral using s110 and another one is as a central using s130. Now central has a very low range to scan peripheral devices while any smartphones can able to scan peripheral. So is there any way to increase it's range.

Put smartphone and central on same distance to peripheral - what RSSI you measure on them?

[Amit Varshney]

RSSI at time is -95dbm

[Wojtek]

on module or on smartphone?

[Amit Varshney]

On smartphone. On module It is not coming in scan list

move it closer, and measure then... If it is close, I would say the peripheral is the one with very poor radio performance. It shows on smartphone, because it has better sensitivity than nRF51. However -95dBm is very poor signal.
