Most of the Zigbee&Bluetooth LE&Thread currently on the market can only run one protocol, but the communication method of the product can be changed by burning 不 with the firmware. The current Telink and Silicon Labs solutions used by Tuya support similar operations, but it is of little significance. The previous Qualcomm solution supports Wi-Fi+Zigbee+Bluetooth LE, but the solution is expensive, and the Qualcomm Zigbee protocol stack is not as mature as its alliance members such as Silicon Labs NXP, and the input-output ratio is not high.
