Is it feasible to use the low-cost feature of 433MHZ frequency band wireless control to replace Bluetooth devices? [Copy link]

As the title says, is it feasible to use the low-cost characteristics of 433MHZ frequency band wireless control to replace Bluetooth devices? Short-range, low-cost and low-speed products are completely feasible

I think it is still quite difficult. 433 is a self-organizing network without connection function, so the packet loss rate will be relatively high and it is also susceptible to interference.

The anti-interference ability of the 433MHZ frequency band is relatively weak.

Simply connect a few devices, definitely 433 a bit more, including the distance can be cost-effective.

Bluetooth itself is a multimedia connection designed for short-range communications within 50 meters, but its bandwidth is many orders of magnitude larger than 433. There is not much comparability between the two. From the perspective of simple needs and functional replacement, there should be no problem.

Bluetooth can communicate confidentially and form networks in various ways, but 433 requires encryption, networking organization and management by yourself.
