Transmit Power Setting

PHY_SET_TRANSMIT_POWER

The TX power level is changed by writing the power level index in the sub register SR_TX_PWR.

Parameters:

txpower

The power level index has a range from 0...15. A mapping between the power level index and the transmit power value in dBm is given in the AT86RF231 datasheet.

Note:

Additionally to the [CONFIG] states, the TX power level can also be changed in RX_AACK_ON in order to reduce the transmit power for an acknowledgement frame.

Code example

    /* AT86RF231::[CONFIG] */
    trx_bit_write(SR_TX_PWR, txpower);

PHY_GET_TRANSMIT_POWER

This sequence reads the power level index from the sub register SR_TX_PWR.

Return values:

txpower

The power level index with a range from 0...15. A mapping between the power level index and the transmit power value in dBm is given in the AT86RF231 datasheet.

Code example

    /* AT86RF231::[ACTIVE] */
    txpower = trx_bit_read(SR_TX_PWR);
