BLE CRC error about tuya-connect-kit-for-mqtt-embedded-c HOT 7 CLOSED

In my case, the problem was with endianness in the tuya_cloud_types.h file. Im swapping the bit order in the "UNI_" macros.

You need to configure the -DLITTLE_ENDIAN=1 or -DLITTLE_ENDIAN=0 compile option depending on your chip platform at compile time.

Or you can define it yourself in the code

Im in the process of porting bluetooth to esp32

Hi, do you have published your code? I'm also interested in the BLE on the ESP32.
Can I have the beginning of your code to test and maybe improve it ?
Thanks

For tuya Wifi provisioning for esp32, you can refer to this: #107 (comment)

I created my own definition in code, but your solution i think is more universal

Hello @shiliu-yang thank you for your code. Right now I have problem because after receiving data there is information that CRC16 has failed. I am not sure but I am using UUID different that you have in your implementation. ESP32 is little endian by default so there is no need to change it. How can I get UUID for device? I think there is a problem so CRC16 is failing. From Tuya knowledge base there is difference between device ID and UUID. I am using Tuyalink based solution.

If you use tuyalink it wont work. This solution is for tuyaOS, then in hardware development you need to use linkSDK (tuya website).
if u want use tuyaLink -> https://github.com/tuya/tuya-iot-core-sdk
