B4R Question data not correctly received using Bluetooth

[Khalid.]

I use this example

HC 05 Classic Bluetooth

In this example we will connect an Android device to an Arduino using class Bluetooth with the HC 05 module. Working with this module is simple. Connect the power and gnd pins and connect the HC05 RX pin to an Arduino TX pin and the HC05 TX pin to an Arduino RX pin. The HC05 RX pin expects 3.3...

and what are messages on serial log ?

Nothing appears

it have a huge delay of about 1 second(in communication RX data pile up) between a request and an answer

You should have a look at the messages received at both ends, BT doesn't always send them as a contiguous series, they get broken up and you need to collect them(usually by knowing the number of bytes being sent or having an end character)
Had this issue myself where BT sent one byte and then the rest... I still don't understand this behavior)

I guess the port is not busy well or at command in bluetooth
