Bluetooth 2. 0 VS Bluetooth 4. 0 (BLE) Is an Upgrade worth it?
video description
Another really important difference is that the HC-05 BT2. 0 boards DO NOT WORK with iPhones. That's because Apple refused to pay the licensing fees for this relatively old BT standard. So if you want your application to work with iPhones then you need to use a more modern BT standard like 4. 0, eg the HM-10.
So, if you care about iPhone compatibility use BT4. 0LE via board like the HM-10.

hello there, i was working on a project using 2 Bluetooth modules to transfer data, but I got some problem and was unable to come over from it. as in the project when we power on the circuit the Bluetooth modules get the connections, but after 5-10 secs they get disconnected automatically and never connect back. can you please help me to solve this problem

The HM-10 presented here is one of the many fake ones. It is lacking the second crystal, which the original HM-10 has. Plus, it has a different firmware with many limitations, higher current in standby, very bad/badly tuned antenna and range, etc. However it can be flashed with the original HM-10 firmware, which eradicates some of these drawbacks.

What I know is the BT 4. 0 shoul'd have much less power consumption. That's the main policy of BT nowdays. Not the speed. You can use the wifi for speed. It is for the lowest power consumption. The BT4 devices will stay online for over 1 year just with the button cell battery.

Funny how the chip used in the bluetooth-module already has a micro-controller included that gives the arduino a run for its money: P
8/16bit timers, 8K Ram, I2C, USART, 12bit ADC - quit a decent thing.

There isn't an explosives expert alive that would fail to sternly warn you about setting off explosives with radio frequency. It's extremely dangerous.

40ms ping is quite a lot actually, is there a lighter weight option to get that down around 1ms? For example, for a mouse or keyboard.

How can I increase range of hc 05 I need it!
Can you suggest some solution! When I go in a different room my BLE does not connect!
