Hi all,

As I know, CC2540 can change TX_POWER to 4, 0 ,-6, -23 dBm by HCI command. Is it possible change it to 2 or 3 dBm? Thanks

It might be possible in theory, but there is not support for it in the ble-stack.

Can it be done from directly write value to CC2540 registers?

Hi YK,

CC2540 BLE project doesn't support "TXPOWER" register. But I can use it in CC2541 project.
