Scan with DSPS Project

Hello,

I'm working in a project with DSPS and I'm trying scanning in central mode but I can only see BL devices (DA14580). I cannot see devices from other manufactures, like Microchip RN4020.

Scanning configuration follows below:

空白app_scanning(空白)
{
ke_state_set(TASK_APP, APP_CONNECTABLE);

// create a kernel message to start the scanning
struct gapm_start_scan_cmd *msg = (struct gapm_start_scan_cmd *)KE_MSG_ALLOC(GAPM_START_SCAN_CMD, TASK_GAPM, TASK_APP, gapm_start_scan_cmd);
// Maximal peer connection
msg->mode = GAP_OBSERVER_MODE;
msg->op.code = GAPM_SCAN_PASSIVE;
msg->op.addr_src = GAPM_PUBLIC_ADDR;
msg->filt_policy=SCAN_ALLOW_ADV_ALL;
msg->filter_duplic = SCAN_FILT_DUPLIC_DIS;
msg->interval = APP_SCAN_INTERVAL;
msg->window = APP_SCAN_WINDOW;

// Send the message
ke_msg_send(msg);
}

int gapm_adv_report_ind_handler(ke_msg_id_t const msgid,
const struct gapm_adv_report_ind *param,
ke_task_id_t const dest_id,
ke_task_id_t const src_id)
{
char temp[150];
int8_t rssi;

if(!memcmp(¶m->report.data[3], APP_DFLT_ADV_DATA, APP_DFLT_ADV_DATA_LEN))
{
//Save found bd_addr to global variable
rssi=(int)(((float)param->report.rssi*0.474)-122);
memcpy(&connect_bdaddr, param->report.adv_addr.addr, sizeof(struct bd_addr));
sprintf(temp,"mac:%0.2x:%0.2x:%0.2x:%0.2x:%0.2x:%0.2x||rssi:%d\r\n",param->report.adv_addr.addr[5],param->report.adv_addr.addr[4],param->report.adv_addr.addr[3],param->report.adv_addr.addr[2],param->report.adv_addr.addr[1],param->report.adv_addr.addr[0],rssi);
sps_uart_sps_write((uint8_t*)temp, strlen(temp));

//app_cancel_scanning();
}
return (KE_MSG_CONSUMED);
}

Thanks,
