CC2640: FCC ETSI with +5dBm

Harald Ilg

Part Number: CC2640

Hy there,

to be able to certify my device in Brazil, apparently I need to enable TX test modes with +5dBm.

So far I am able to execute the command:

HCI_EXT_ModemTestTxCmd(HCI_EXT_TX_UNMODULATED_CARRIER,freq); and HCI_EXT_ModemTestTxCmd(HCI_EXT_TX_MODULATED_CARRIER,freq);

but does this set the TX power tp +5dBm? In http://processors.wiki.ti.com/index.php/FCC_ETSI_Test I find that 0dBm is used.

When I browse my source code I find the declaration of a function LL_EXT_ModemTestTx in ll.h. The comment reads:

Note: The BLE device will transmit at maximum power.

Is maximum power +5dBm? Can I simply call this function to enable test mode? Can I influence TX power on the test mode activated with HCI_EXT_ModemTestTxCmd?

Regards

Hi,

If you look at the Vendor Specific Guide (found in C:\ti\simplelink\ble_sdk_2_02_01_18\docs) the description of this API says you can change the output power using the HCI_EXT_SetTxPowerCmd otherwise defaults at 0dBm.

Hy,

that's a good info. Do you know when I need to call this command? Before entering the test mode? After entering the testmode? I would go and try but don't have HF measurement euipment on hand...

Yes, i would call it before entering test mode for example in your initialization function.

Best wishes
