Connecting a servo via HC05 and HC06 I want to drive a servo via a HCO6 and HC05 link as a stand alone, using no android or PC. 
The question is how to send a 1.5 ms signal (generated with a pulse command on a Nano) from one HC to another HC (to which my servo will be connected) ?
I do not need to care about passwords in my linking. No text to be sent, just the 1ms to 2 ms signal, at a refresh rate of 50 Hz.
I will use the HC with a OOK modulation (on - off on the data pin)?
How to achieve this ?
Thanks !
You cannot. You will need an Arduino at the servo end to generate the PWM signal from serial instructions sent over Bluetooth.

Since PWM is (typically) 8-bit and serial is (typically) 8-bit you could simply have each byte as a 1:1 mapping to a PWM value.

One the transmit end:

bluetoothSerial.write(pwmValue);


On the receive end:

if (bluetoothSerial.available()) {
    analogWrite(9, bluetoothSerial.read());
}
