Error trying to change filter parameters to filter by name on UART example

[sotillo2409]

Hi everyone,

I am working on nrf Connect 3.7.0, SDK v1.6.1 with a nrf52840.

I am not able to change the filter of scanning, only works with UUID filter.

static int scan_init(void)
{
int err;
const char *perName="Uart_periph1";
//static char const test_periph_addr[] = {0x17, 0x49, 0xB7, 0xBE, 0xC4, 0xDC};
struct bt_scan_init_param scan_init = {
.connect_if_match = 1,
.scan_param = &m_scan_param,
.conn_param = NULL,//&m_conn_param,
};

bt_scan_init(&scan_init);
bt_scan_cb_register(&scan_cb);

//err = bt_scan_filter_add(BT_SCAN_FILTER_TYPE_UUID, BT_UUID_NUS_SERVICE);
//if (err) {
// LOG_ERR("Scanning filters cannot be set (err %d)", err);
// return err;
//}

//err = bt_scan_filter_enable(BT_SCAN_UUID_FILTER, false);
//if (err) {
// LOG_ERR("Filters cannot be turned on (err %d)", err);
// return err;
//}

err = bt_scan_filter_add(BT_SCAN_FILTER_TYPE_NAME,perName);

if (err) {
LOG_ERR("Scanning filters cannot be set (err %d)", err);
return err;
}

err = bt_scan_filter_enable(BT_SCAN_FILTER_TYPE_NAME, false);
if (err) {
LOG_ERR("Filters cannot be turned on (err %d)", err);
return err;
}

LOG_INF("Scan module initialized");
printk("Scan module initialized");
return err;
}

Debugging the error occurs here bt_scan_filter_enable:

This is the main Kconfig part:

The scanning is maked only on coded. I don't know why but on autoconfig.h generated by the compiler...

The filter by name can't be setted.

I am so really stuck, any ideas are welcome

Thanks, regards.

If i use the default scann with UUID i haven't any problem for scan, but my devices never connect. I will change the filter because i read on documentation that on coded phy isn't possible use this UUID filter.

It's so strange, when i change autoconfig.h manually to set:

#define CONFIG_BT_SCAN_UUID_CNT 0
#define CONFIG_BT_SCAN_NAME_CNT 1
#define CONFIG_BT_SCAN_SHORT_NAME_CNT 0

 When I build the project, there aren't errors and my scan starts. But autoconfig.h is modified automatically by the compiler i think, and Segger studio ask me if i want to reload the project, if i accept autoconfig.h seems like:

#define CONFIG_BT_SCAN_UUID_CNT 1
#define CONFIG_BT_SCAN_NAME_CNT 0
#define CONFIG_BT_SCAN_SHORT_NAME_CNT 0

And if i build that project with that autoconfig.h i get the error described previously. I do't know why is my autoconfig modified automatically when i build, and why is modified always with the same parameters, independenly of my code.
