Hi
Im fairly new to all this arduino, and bought a couple of different modules. I have a relay and a HM-10 Bluetooth module as this one in the link.
I would like to connect both to the arduino, to be able to turn on/off various 220V AC stuff around the house.
however im having trouble connecting to it. I have tried various tuturials online, and nothing seems to work.
I followed this tut -
Open the Arduino software, then upload Examples -> SoftwareSerial -> SoftwareSerialExample to your device
Connect
HM-10 TX - Arduino Pin 10 softRX
HM-10 RX - Arduino Pin 11 softTX
HM-10 GND - Arduino GND
HM-10 VCC - Arduino 3.3V
Open the serial monitor at 9600 baud.
Commands
The BLE module uses AT Commands to read and write system information, they do not need to be followed by a line break. If you don't get a response when you enter a command something may not be connected properly and you'll need to troubleshoot your module.
When you're connected type:
AT - it should respond with OK
You can find your firmware version:
AT+VERS? - firmware version
And set your device's name:
AT+NAME? - get current name
AT+NAMEyourname - set the name (12 chars max)
But it does'nt work.
When i wirte AT in the serialmonitor, It does absolutely nothing.
At first by accident i connected the module by 5V, so im afraid it's burned, but i still blinks. any way to test this?
My phone can identify the module as HC05 but fails to connect, and doesn't even ask for password.
and my pc identify 3 "unknown" bluetooth devises both can't connect to any of them?
any suggestions? hope to get some help as im totally lost here :o
Best regards Martin
