#Bluetooth remote controller

Bluetooth remotes work the same way as Infrared remotes, but instead of sending light pulses, they send the codes to the device via radio waves. Bluetooth uses RF signals to operate, and RF remotes are more expensive as there are fewer frequencies for them to use, and they still may experience interference from other RF devices, according to 1000Bulbs. Furthermore, unlike Infrared, Bluetooth also allows transmission even through walls and other objects, and there is no need to point the remote to the device, as it does not require to be in the line of sight. Plus, Bluetooth also requires you to manually connect the remote control for the first time. This is because IR remotes need cheaper parts than Bluetooth remotes. Besides the parts, a Bluetooth remote also has certification and licensing costs, which will be passed on to the consumers. That's why you mostly see IR remotes on standard TVs and Bluetooth remotes on more expensive Smart TVs or Android-powered TV boxes. However, Bluetooth remotes take an advantage over Infrared in effective range, and it doesn't need line-of-sight to function, providing more flexibility and convenience.
