Regards,

i have gone through your shared link .

i am getting good range when i am using same program on launchpad but as i flash the software on our Custom board , range becomes much less hardly around half meter.

i am using internal RC oscillator and also used HCI_EXT_SetTxPowerCmd(HCI_EXT_TX_POWER_5_DBM) command to set tx power to 5dbm in my simple central init .

Note: i am sure that there is no hardware issue on our custom board.

Hi,

What is the range when you use launchpad?

Can you share the hardware design for review?

Regards
