Interface and connectivity ICs

I have configured my Bluenrg2 with the help of Bluenrgsdk module with Data Length Extension of 251 bytes and ATT_MTU as 247 and I have acheived a throughput speed around 300kbps but range is the main problem,it gets disconnected if i go beyond 3meters.

I am using BLE_Throughtput_Ext program from Bluenrgsdk version 3.1.0.I have also configured Tx power levels from -14dbm to 8dbm and the results are same(I can see very small variation in my distance of around 2m) as the distance increases my data rat...
