Dear All,

I am using SmartRF06 Evaluation board and CC13xx EM with contiki 3.0 to develop my application.

But now I have encountered two problems .

1. How to print debug messages to uart ?

2. Can I run my app with RFband from 480.1 Mhz to 485.5 Mhz ?

I have modified my code as below:

file: Dot-15-4g.h

#define DOT_15_4G_FREQUENCY_BAND_ID DOT_15_4G_FREQUENCY_BAND_470

#define DOT_15_4G_CHANNEL_MAX 675
#define DOT_15_4G_CHANNEL_SPACING 8
#define DOT_15_4G_CHAN0_FREQUENCY 480100
#define PROP_MODE_CONF_LO_DIVIDER 0x0A

Thanks.

UART print is enable by default in Contiki srf06+CC13xx example so you can use printf to output debug message directly.

I think you are correct to modify Dot-15-4g.h.

The Wiki has some information here:

http://processors.wiki.ti.com/index.php/Cc26xx_sw_examples

"Changing the RF Band

The default RF band used is at 868 MHz, In order to change the RF band one has to edit the file ~/contiki/platform/srf06-cc26xx/contiki-conf.h to include the following line to change to XXX MHz #define DOT_15_4G_CONF_FREQUENCY_BAND_ID DOT_15_4G_FREQUENCY_BAND_XXX. Supported frequency bands are listed in the file ~/contiki/cpu/cc26xx-cc13xx/rf-core/dot-15-4g.h."
