Hello,

I would like to modify the following define in mac_pic.h :

#define MAC_GENERIC_ETSI_863_BAND_MODE_2_CENTER_FREQ_KHZ 863225

Indeed, i would like to define it to 869525 to be able to have channel 0 in this bandwidth : 869,400 MHz to 869,650 MHz where ETSI allows to emits up to 500 mW.

But it is defined in simplelink SDK; how to modify it without touching to simplelink.

Thank you in advance,

Best regarde,

Hi Marc,

You have to modify the header file if you want to the specific frequency you are asking for.

Hello,

Thank you very much.

Indeed, this define is used in the following table :

macMRFSKPHYDesc_t macMRFSKGenPhyTable[MAC_GENERIC_PHY_DESCRIPTOR_ENTRIES] =
{
 { MAC_GENERIC_CHINA_433_BAND_MODE_1_CENTER_FREQ_KHZ, MAC_GENERIC_CHINA_433_BAND_MODE_1_CHAN_SPACING_KHZ,
   MAC_GENERIC_CHINA_433_BAND_MODE_1_TOTAL_CHANNELS, MAC_2_FSK_MODULATION, MAC_MRFSK_SYMBOL_RATE_50_K,
 MAC_MODULATION_INDEX_2FSK_50K,
   MAC_CCA_TYPE_CSMA_CA },
 { MAC_GENERIC_US_LRM_915_BAND_MODE_1_CENTER_FREQ_KHZ, MAC_GENERIC_US_LRM_915_BAND_MODE_1_CHAN_SPACING_KHZ,
   MAC_GENERIC_US_LRM_915_BAND_MODE_1_TOTAL_CHANNELS, MAC_2_FSK_MODULATION, MAC_MRFSK_SYMBOL_RATE_20_K,
 MAC_MODULATION_INDEX_2FSK_5K,
   MAC_CCA_TYPE_CSMA_CA },
 { MAC_GENERIC_CHINA_LRM_433_BAND_MODE_1_CENTER_FREQ_KHZ, MAC_GENERIC_CHINA_LRM_433_BAND_MODE_1_CHAN_SPACING_KHZ,
   MAC_GENERIC_CHINA_LRM_433_BAND_MODE_1_TOTAL_CHANNELS, MAC_2_FSK_MODULATION, MAC_MRFSK_SYMBOL_RATE_20_K,
 MAC_MODULATION_INDEX_2FSK_5K,
   MAC_CCA_TYPE_CSMA_CA },
 { MAC_GENERIC_ETSI_LRM_863_BAND_MODE_1_CENTER_FREQ_KHZ, MAC_GENERIC_ETSI_LRM_863_BAND_MODE_1_CHAN_SPACING_KHZ,
   MAC_GENERIC_ETSI_LRM_863_BAND_MODE_1_TOTAL_CHANNELS, MAC_2_FSK_MODULATION, MAC_MRFSK_SYMBOL_RATE_20_K,
 MAC_MODULATION_INDEX_2FSK_5K,
   MAC_CCA_TYPE_LBT },
 { MAC_GENERIC_US_915_BAND_MODE_3_CENTER_FREQ_KHZ, MAC_GENERIC_US_915_BAND_MODE_3_CHAN_SPACING_KHZ,
   MAC_GENERIC_US_915_BAND_MODE_3_TOTAL_CHANNELS, MAC_2_FSK_MODULATION, MAC_MRFSK_SYMBOL_RATE_200_K,
 MAC_MODULATION_INDEX_2FSK_200K,
   MAC_CCA_TYPE_CSMA_CA },
 { MAC_GENERIC_ETSI_863_BAND_MODE_2_CENTER_FREQ_KHZ, MAC_GENERIC_ETSI_863_BAND_MODE_2_CHAN_SPACING_KHZ,
   MAC_GENERIC_ETSI_863_BAND_MODE_2_TOTAL_CHANNELS, MAC_2_FSK_MODULATION, MAC_MRFSK_SYMBOL_RATE_200_K,
 MAC_MODULATION_INDEX_2FSK_200K,
   MAC_CCA_TYPE_LBT },
};

But can i add a new configuration to this table ? If yes, how to use it ?

Regards,

Aurélien
