【已解决】【TuyaOs】请教下如何扫描蓝牙遥控原始数据

[wxq1123]

1）开发包全称：tuyaos-iot_3.8.1_bk7231n_wifi-ble-com_1.2.8.tar.gz
2）问题现象：请问下如何正确注册“tuya_ble_reg_raw_scan_adv_cb（）”这个函数才能查看原始的蓝牙广播数据（非涂鸦 Beacon协议）。目前在example工程的 “example_ble_remote.c”文件里添加的，可能方法不对没有起到作用。求教正确方法。

我按您的要求把代码复制过去，也添加了open_bind函数，可是还是看不到数据呢，手机用蓝牙工具APP能看到。您看下是哪里出的问题（补充下，遥控的数据目前只在广播的38信道发送数据）

[bamy]

1）tuya_ble_set_bind_window(0)后再open，可以永久打开时间窗
2）用NRF查看下是否能扫到你的beacon包，是否符合标准

应该符合什么样的标准呢？以前老的tuyaos用“esp_hal_ble_gap_set_event_cb（）”注册回调后能能在“case ESP_GAP_BLE_SCAN_RESULT_EVT：”里面收到数据的。遥控数据的NRF接收如下图

1）tuya_ble_set_bind_window(0)后再open，可以永久打开时间窗
2）用NRF查看下是否能扫到你的beacon包，是否符合标准

或者有其他接口能接收蓝牙广播数据吗？

[hearge]

广播的类型可以改下么？不太确定是不是因为这个类型导致的，改成BrEdrNotSupported类型试下。

改了 ，还是不行

[hearge]

需要把GeneralDiscoverable 这个加上。目前除这三种的广播类型ADV_IND，SCAN_RSP，NONCONN_IND 的类型之外，其他类型都会过滤掉。

“广播类型ADV_IND，SCAN_RSP，NONCONN_IND ”是指截图中 目前“Legacy”这个类型吗
