How to get S2-LP into CW mode?

Hi,

I have the ST S2-LP transceiver both transmitting and receiving just fine however i'm struggling to put the chip into a continuous wave mode.. 

from reading the data sheet i have configure the following : 

• To set the continuous wave the TXSOURCE field (of the PCKTCTRL1 register) must be set to 0x03

• To set the continuous wave the MOD_TYPE field (of the MOD2 register) must be set to 0x70

Is there any additional registers i should be aware of in order to configure continuous wave mode?

Thanks

Ed

I forgot to start transmitting...

S2LPCmdStrobeTx();

All works now

Hi Eddie,

Were there any steps before sending these commands.

I used the S2LP libraries like this:

S2LP_RADIO_SetModulation( MOD_NO_MOD);

S2LP_PCKT_HNDL_SetTxMode(PN9_TX_MODE);

S2LP_CMD_StrobeTx();

But no TX happening.

It's flagging a Hard Fault Interrupt.

I tried to initialize the radio by copying some codes from the example under X-CUBE-SUBG2 package.

But still no luck.

Any help will be appreciated.
