Projects General Guidance

First of all, I'm not good at English. Sorry about that

I'll try to explain my problem as well as i possible

This is my Code.

#include <SoftwareSerial.h>

#define BT_RXD 8
#define BT_TXD 9

SoftwareSerial bluetooth(BT_RXD, BT_TXD);

void setup() {
Serial.begin(9600);
bluetooth.begin(9600);
}

void loop() {
if (bluetooth.available()) {
Serial.write(bluetooth.read());
}

if (Serial.available()) {
bluetooth.write(Serial.read());
}
}

I have two HM-10, and one UNO, and LEONARDO

I uploaded that code to both arduinos.

and used AT comman like this

AT+ROLE
using this command, I distinguished between master and slave

AT+ADDR
using this command to slave, I checked slave module's address

AT+INQ
using this command to master, I find connectable device near me

AT+CONN
using this command to master, I connected two HM-10 each other

After connecting, the two HM-10's led turs on without blank

So, I think they are connected without problem

I expected that if I type something to Serial monital, then I can see that on the other side of arduino's Serai monital

But, it doesn't work even I type anything include AT commands

When before I connect two modules each ohter, I tried connect the module with my phone using terminal app, one by one.

In that time I succeded transfer some word both of HM-10

But, if I connected HM-10 each other, then I can't transfer any words as I said

Please help me

You are trying to use an HM-10 in the same way as an HC-05. I think this is confusing, unreliable, and a bad idea. You might get some help from the Martyn Currey website. You might need the Bluetooth Connect library.g
