KC868-H32B V5.08 firmware
#1
fixed bug for tuya connection with cloud server.
firmware download: 

.zip   H32B_V508_230921.zip (Size: 134.93 KB / Downloads: 396)
make sure your KC868-H32B CPU chip is AT32F403AVGT7.
if your board CPU is STM32F103VCT6 or GD32F103VCT6, there is no enough memory for new firmware update, they memory is 256K. new firmware is >300k, so can't use it.

STM32F103VCT6 support MAX firmware 128K size, so you need download a older firmware , file <128K.

If using j-link, can it work?
