    0
  • O

    应该是广播包的字段里面有影响

    0
  • N

    • 需要自己去修改广播内容，修改服务uuid 那一项。

    • 因为在广播包中有个字段声明了自己是 HID 设备，所以手机扫描到后是键鼠的图标。

    • 代码如下

    void at_init_advertising_parameter(void)
    {

    uint8_t *pos;
uint8_t adv_data[0x1C];
uint8_t adv_data_len = 0;

pos = &adv_data[0];
uint8_t manufacturer_value[] = {0x00,0x00};
*pos++ = sizeof(manufacturer_value) + 1;
*pos++  = '\xff';
memcpy(pos, manufacturer_value, sizeof(manufacturer_value));
pos += sizeof(manufacturer_value);

uint16_t uuid_value = 0xFF03  ;  // 将 HID_SERV_UUID 改成你想设置的 任意 2字节 UUID
*pos++ = sizeof(uuid_value) + 1;
*pos++  = '\x03';
memcpy(pos, (uint8_t *)&uuid_value, sizeof(uuid_value));
pos += sizeof(uuid_value);
adv_data_len = ((uint32_t)pos - (uint32_t)(&adv_data[0]));

gap_adv_param_t adv_param;
adv_param.adv_mode = GAP_ADV_MODE_UNDIRECT;
adv_param.adv_addr_type = GAP_ADDR_TYPE_PUBLIC;
adv_param.adv_chnl_map = GAP_ADV_CHAN_ALL;
adv_param.adv_filt_policy = GAP_ADV_ALLOW_SCAN_ANY_CON_ANY;
adv_param.adv_intv_min = adv_int_arr[gAT_buff_env.default_info.adv_int];
adv_param.adv_intv_max = adv_int_arr[gAT_buff_env.default_info.adv_int];
gap_set_advertising_param(&adv_param);
gAT_ctrl_env.curr_adv_int = adv_param.adv_intv_min;

gap_set_advertising_data(adv_data,adv_data_len);
at_init_adv_rsp_parameter();

    }
