3.7 The Difference Between HCI_EXT_ModemTestTxCmd and HCI_LE_Transmitter_Test

For FCC regulatory testing, set HCI_EXT_ModemTestTxCmd (or HCIExt_EnhancedModemTestTxCmd for different PHY rate) instead of HCI_LE_Transmitter.

The HCI_EXT_ModemTestTxCmd includes an input for modulated or unmodulated carrier. Before setting HCI_EXT_ModemTestTxCmd, set the HCIExt_SetTxPowerCmd for Tx power.

After it has been sent the HCI_LE_Transmitter_Test command, the CC26xx/CC13xx device sends out LE test packets. This can be used for In-band emission. The HCI_LE_TransmitterTest command configures the Bluetooth LE device to transmit at maximum power. To change the TxPower used, use the command HCI_EXT_SetMaxDtmTxPowerCmd in advance.

Below summarizes the test commands for different tests:

  • For FCC testing, set HCIExt_SetTxPowerCmd, then set HCIExt_ModemTestTxCmd (or HCIExt_EnhancedModemTestTxCmd)
  • For in-band emission testing, set HCI_EXT_SetMaxDtmTxPowerCmd, then set HCI_LE_Transmitter_Test.

[11] and [12] provide the details for the HCI commands.
