Bluetooth module at mode (idk if my category is correct)

Using Arduino Project Guidance
1

Greetings! I got one of those Christmas trains you see going around the tree, oddly for Christmas. But I wanted to mod it, so i took an Arduino uno r3 I had and a bt-05 and tried to connect the module to my phone. Didnt work, I tried 1234 but it didnt pair, it just kept the pairing screen on, until it timed out. So, I tried using at mode to change the pin. I tried setting the baud rate to 38400 and test it by entering AT, it was suppose to return OK, but instead, (note I cant copy the serial text, so ill recreate it with brackets) it put
[]x[][][][]x[][]x[][][][][]xx[][][]

Heres my pin to pin wiring, Module ==> Arduino

VCC ==> 5V

GND ==> GND

TXD ==> 10

RXD ==> 11

and heres the code

#include <SoftwareSerial.h>

SoftwareSerial mySerial(10, 11); // RX, TX

void setup() {

Serial.begin(9600);

pinMode(9,OUTPUT); digitalWrite(9,HIGH);

Serial.println("Enter AT commands:");
delay(200);
mySerial.begin(38400);

}

void loop()  {

if (mySerial.available())

Serial.write(mySerial.read());

if (Serial.available())

mySerial.write(Serial.read());

}

Could be '0000'

tried that, no go

What do you want assistance with?

Apparently, a BT-05 is BLE.

5

Ok, i have 3 issues

1 I cant connect to my module
2 I tried changing the pin so I could know for sure what the pin is, unfortunately see 3
3 I cant enter AT cmds to change the pin

6

Oh, and i have no idea if im even in at mode, the little red led is going on and off with about a second in between

Seems that there's no hardware config to get AT mode.

3 BLE is in AT mode by default @ 9600.

2 If in the unlikely event you need a password, it will
be 6 digits. Try 123456.

1 Ensure terminal is BLE compatible.

Ok, now i can enter AT cmds, I just can't see it on my phones bt list

10

Is your moblle BLE-capable?

11

Well, before i used AT mode i was able to see it, so I assume yes. How do I exit at mode?

12

Since you don't invoke AT mode, I'd assume exiting would be the same.

I ordered a couple of HM10. They may be in the locker tomorrow.
Asked to guess -- perhaps AT+DISC

13

Error, it just says error in all caps

14

Nevermind, it works now

15

What was the hang-up?

16

Hang up?

17

What was the problem then?

18

ok, new problem. Im using an app to communicate with the bt-05, but cmds dont go through. im using Bluetooth Serial Monitor on android and when i type AT, nothing
