【Telink - 泰凌 TL322X 开发板】channle sounding测试篇
本帖最后由 eefocus_4231172 于 2026-7-6 20:52 编辑一、前言
本篇使用BLE6.0的CS特性进行测距实验，使用TL322X作为主机，nRF54L15作为从机进行测试。
二、SDK和DEMO的使用介绍
1、主机TL322X使用DEMO
2、从机nRF54L15使用DEMO
三、开发板展示以及接线
1、泰凌微TL322X开发板
2、Nordic nRF54L15开发板
四、正文
4.1、泰凌微TL322X的程序修改
1、扫描连接逻辑更改
如上图所示，找到app.c中的app_le_adv_report_event_handle(u8 *p)函数，更改成上图所示的语句，该语句的意思是只要扫描到“cs-telink”的广播名就开始进行连接。
2、增加安全配对
如上图所示，增加安全配对，在user_init_normal(void)函数中。
3、增加上电开始扫描逻辑
如上图所示，打开扫描，在user_init_normal(void)函数中。
4、选择单天线
在“tl_ble_sdk\vendor\common\boards\TL322X_C1T382A102.h”中将ANTENNA_SWITCHING_AUTO_EN设置为0
4.2、Nordic nrf54L15的程序修改
1、广播名修改
如上图所示，将广播名更改为“cs_telink”
2、广播数据修改
static const struct bt_data ad[] = {
BT_DATA(BT_DATA_NAME_COMPLETE, CONFIG_BT_DEVICE_NAME, sizeof(CONFIG_BT_DEVICE_NAME) - 1),
BT_DATA_BYTES(BT_DATA_FLAGS, (BT_LE_AD_GENERAL | BT_LE_AD_NO_BREDR)),
// BT_DATA_BYTES(BT_DATA_UUID16_ALL, BT_UUID_16_ENCODE(BT_UUID_RANGING_SERVICE_VAL)),
BT_DATA_BYTES(BT_DATA_UUID16_SOME, BT_UUID_16_ENCODE(BT_UUID_RANGING_SERVICE_VAL)),
};
如上图所示，修改广播数据
3、安全配对修改
如上图所示，增加安全配对相关的内容
4、增加打印，和配对相关的内容
