compiler seems correct in saying this is an error:

middleware/mqtt_client_wrapper.c:188:40: error: comparison between 'enum mqtt_client_status' and 'MQTTStatus_t' {aka 'enum MQTTStatus'} [-Werror=enum-compare]
         if (MQTT_STATUS_NOT_AUTHORIZED != mqtt_status) {
            return MQTT_STATUS_NOT_AUTHORIZED;
        }

I think it should be:

        if (MQTTServerRefused == mqtt_status) {
            return MQTT_STATUS_NOT_AUTHORIZED;
        }

Right now I am porting code to ESP32 but there is one problem with Wifi provisioning that device is receiving data which is 20 bytes only. From code it looks like we should receive more.

我计划将esp32接入涂鸦.
官方文档介绍了许多接入方式.

Tuya MQTT协议接入
IoT Core SDK（C）
Tuya Connect Kit
TuyaLink
TuyaOS Link SDK

请问当前主要维护哪些方式呢. 麻烦推荐一个,给个文档.

并且不同的方式创建产品,所使用的授权码也不一样. 应该使用什么方式创建设备?
授权码-通用版 和 设备接入授权码 . 这2个有什么区别,该使用哪一个呢

Hi Tuya team,
I have some problem of using the demo. It's said that "MQTT connection failed: 3", more detail about this error can be found in the attached file.
Could you please give me a detail instruction on how to run the demo?

我看教程里是由docs文档目录的，怎么这里没有呢，求解答

the code don't have this file.

Hi, Im in the process of porting bluetooth to esp32, my device is detected by the tuya app, currently it stops at crc after receiving the first frame. For example, the frame I received: 0x00.0x31.0x40.0x01.0xA4.0x62.0xD5.0x33.0x09.0x56.0xC4.0xF5.0x1B,0xBB,0x3C,0xF7.0xBB,0xEA,
0x38.0x86.0x32.0xF8.0x94.0x84.0xCF,0xDA,0x1F,0x3C,0x5B,0xF3,0x33.0x16.0xEF,0x9F,0xA5,0xD5,
0x24.0xBE,0x0B,0x8F,0x20.0x9C,0x06.0xA3.0xCD,0x47.0xCB,0xD1.0x1A,0xA7.0x26.0x47
Each time is 52 bytes.
I get an error: 00:00:17 ERROR tuya_ble_service.c:467: receive data crc16 check fail
00:00:17 ERROR tuya_ble_service.c:791: ret:-1
Is anyone able to help me?

After several successful updates, a timeout error appears.
I can still download the firmware that was uploaded on the tuya website a few days ago, but cannot download the firmware that was updated today.

compiler suggests this:

middleware/mqtt_client_wrapper.c:98:30: error: argument to 'sizeof' in 'memset' call is the same expression as the destination; did you mean to dereference it? [-Werror=sizeof-pointer-memaccess]
     memset(context, 0, sizeof(context));

I think it's correct, should be:

    mqtt_client_context_t* context = (mqtt_client_context_t*)client;
    MQTTStatus_t mqtt_status;

    /* Clean memory */
    memset(context, 0, sizeof(*context));

连接服务器出现错误mqtt connect err: Connection not authorized(11)
检查了Product ID, Device UUID, Device Secret都应该没错。

请问还可以检查哪些地方调查这个问题？

怎么移植到esp32，能否提供demo，手动移植了一直显示tls连接失败

Does anyone know where the tutorial documentation is?Help me, please!
