CC2640R2F: How to increase maximum transmission power in Project Zero Application

Hi,

The TX power can be changed from ble_user_config.c file which locates in ICallBLE folder.

// Tx Power Table
txPwrTbl_t appTxPwrTbl = { TxPowerTable,
                           NUM_TX_POWER_VALUES,  // max
                           DEFAULT_TX_POWER };   // default

  // Tx Power Values (Pout, IB, GC, TC)
  const txPwrVal_t TxPowerTable[] =
  { { TX_POWER_MINUS_21_DBM, GEN_TX_POWER_VAL( 0x07, 3, 0x0C ) },
    { TX_POWER_MINUS_18_DBM, GEN_TX_POWER_VAL( 0x09, 3, 0x0C ) },
    { TX_POWER_MINUS_15_DBM, GEN_TX_POWER_VAL( 0x0B, 3, 0x0C ) },
    { TX_POWER_MINUS_12_DBM, GEN_TX_POWER_VAL( 0x0B, 1, 0x14 ) },
    { TX_POWER_MINUS_9_DBM,  GEN_TX_POWER_VAL( 0x0E, 1, 0x19 ) },
    { TX_POWER_MINUS_6_DBM,  GEN_TX_POWER_VAL( 0x12, 1, 0x1D ) },
    { TX_POWER_MINUS_3_DBM,  GEN_TX_POWER_VAL( 0x18, 1, 0x25 ) },
    { TX_POWER_0_DBM,        GEN_TX_POWER_VAL( 0x21, 1, 0x31 ) },
    { TX_POWER_1_DBM,        GEN_TX_POWER_VAL( 0x14, 0, 0x42 ) },
    { TX_POWER_2_DBM,        GEN_TX_POWER_VAL( 0x18, 0, 0x4E ) },
    { TX_POWER_3_DBM,        GEN_TX_POWER_VAL( 0x1C, 0, 0x5A ) },
    { TX_POWER_4_DBM,        GEN_TX_POWER_VAL( 0x24, 0, 0x93 ) },
    { TX_POWER_5_DBM,        GEN_TX_POWER_VAL( 0x30, 0, 0x93 ) } };

The default output power is set to 0dBm which is the 8th element in the TxPowerTable(index=7= DEFAULT_TX_POWER).

To change the value you can change the DEFAULT_TX_POWER value.
