CCS/CC1350: sendScanReq(ApiMac_scantype_t type)

Hello,

CAn you explain more on the software and hardware side of things?

What are you using in terms of software?

What version of SDK?

Where are you changing this channel mask?

REgards,

AB

Hi AB,

First of all thank you very much for taking time and responding my question.

 Regarding the software side I am using :

CCS V_8

the SDK I am using is     simplelink_cc13x0_sdk_3_20_00_23 to be specific  

                            collector_CC1310_LAUNCHXL_tirtos_ccs  and collector CC1350_LAUNCHXL_tirtos_ccs.

the changes I did  are as follows :  

in config.h      the value of 

#define CONFIG_CHANNEL_MASK { 0xFF, 0xFF, 0x11, 0x00, 0x00, 0x00, \
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, \
0x00, 0x00, 0x00, 0x00, 0x00 }

static void sendScanReq(ApiMac_scantype_t type)
{
ApiMac_mlmeScanReq_t scanReq;
/* set common parameters for all scans */
memset(&scanReq, 0, sizeof(ApiMac_mlmeScanReq_t));
/* set scan channels from channel mask*/
memcpy(scanReq.scanChannels, chanMask,
APIMAC_154G_CHANNEL_BITMAP_SIZ);
scanReq.scanType = type;
scanReq.scanDuration = CONFIG_SCAN_DURATION;
scanReq.maxResults = 6;/* Expecting beacon notifications */
scanReq.permitJoining = false;
scanReq.linkQuality = 1;
scanReq.percentFilter = 0xFF;
scanReq.channelPage = CONFIG_CHANNEL_PAGE;
scanReq.phyID = CONFIG_PHY_ID;
/* using no security for scan request command */
memset(&scanReq.sec, 0, sizeof(ApiMac_sec_t));
/* send scan Req */
ApiMac_mlmeScanReq(&scanReq);
}

Hardware  types are  CC1310 and CC1350 launchpads 

for your information  my  scanCnfCb(ApiMac_mlmeScanCnf_t *pData) function  is in collector.c file that is used to display the values returned from energy scan.

Thank you . 

Hi AB,

enable the erase entire flash is selected by default and I tried but not working.

Regarding the 2nd option where I have to disable it ?

I see  the file in : 

1,  under      csf.c     

void Csf_init(void *sem)
{
#ifdef NV_RESTORE
/* Save off the NV Function Pointers */
pNV = &Main_user1Cfg.nvFps;
#endif

2,    under        main.c 

#ifdef NV_RESTORE
mac_Config_t Main_user1Cfg =
{ 0 };
#endif

3,  under cllc.c

#ifndef NV_RESTORE
/* If NV_RESTORE is disabled device gets a new short address every time it
joins i.e there may be duplicate entries in the Association table
*/
devInfo.shortAddress = CSF_INVALID_SHORT_ADDR;
#else
/* Check to see if the device exists */
devInfo.shortAddress = Csf_getDeviceShort(&pData->deviceAddress);
#endif

So where I have to look for disabling NV_RESTORE parameter?

Thank you. 

Hi AB,

For your information,  I am trying to develop a star network of collectors where one of them  would periodically send Energy scan measurements to the central  controller(BeagleBone Black). So my  question beside where to disable  NV_RESTORE is  disabling NV_RESTORE will not affect the normal functioning of the collector?

Thank you.

Hi  AB,

First of all thank you for taking time and responding.

Now I am getting the scanned  channels  and their  energy  level. but  still i have a problem with counting total number of channels returned from energy scan. 

below attached the code  

static uint8_t findBestChannel(uint8_t *pResults)
{
uint8_t chan;
uint8_t currEnergy;
uint8_t lastEnergy = CLLC_MAX_ENERGY;
uint8_t coordStartChan = 0;
LCD_WRITE_STRING_VALUE("Total number of channels: ", sizeof(pResults), 10,6);

I tried   to get  through pData->resultListSize but it will return 129 which is the total channel not the number of scanned once. So, how can I solve ?

Thank you.
