Do you have the source available for the C# app? I would love to see how you're communicating with the device. Unfortunately, I can't run an exe directly (security risk).

Thanks a lot!

Hi I have tried to communicate the bluetooth serial port from HC-05 for one of my project same as like the program you uploaded in this page (C# Test Program). I can search the available bluetooth devices in my range and also can pair with it. But i cannot connect through my C# program. In short words i have a HC-05 device that is sending the character "A" continuously via its serial port, i need to read that character and display it in a text field.

Here is my code blocks <br> private void btnSearch_Click(object sender, EventArgs e) { BluetoothRadio.PrimaryRadio.Mode = RadioMode.Discoverable; BluetoothRadio myRadio = BluetoothRadio.PrimaryRadio; lblSearch.Text = "" + myRadio.LocalAddress.ToString(); BtClient = new BluetoothClient(); Cursor.Current = Cursors.WaitCursor; BluetoothDeviceInfo[] bluetoothDeviceInfo = { }; bluetoothDeviceInfo = BtClient.DiscoverDevices(10); cmbDevicesFound.DataSource = bluetoothDeviceInfo; cmbDevicesFound.DisplayMember = "DeviceName"; cmbDevicesFound.ValueMember = "DeviceAddress"; cmbDevicesFound.Focus(); Cursor.Current = Cursors.Default; foreach (BluetoothDeviceInfo b in bluetoothDeviceInfo) { listBox1.Items.Add(b.DeviceAddress.ToString()); } }

private void btnPair_Click(object sender, EventArgs e) { if (cmbDevicesFound.SelectedValue != null) { try { BluetoothSecurity.PairRequest((InTheHand.Net.BluetoothAddress)cmbDevicesFound.SelectedValue, "1234"); } catch (Exception ex) { MessageBox.Show(ex.Message); } } }

private void btnConnect_Click(object sender, EventArgs e) { if (cmbDevicesFound.SelectedValue != null) { try { MessageBox.Show(cmbDevicesFound.SelectedValue.ToString()); InTheHand.Net.BluetoothEndPoint Ep = new Net.BluetoothEndPoint((InTheHand.Net.BluetoothAddress)cmbDevicesFound.SelectedValue, BluetoothService.SerialPort); bool t = false; BluetoothClient cli = new BluetoothClient(); cli.Connect(Ep); t = cli.Connected; MessageBox.Show(t.ToString()); MessageBox.Show("Connected"); } catch (Exception ex) { MessageBox.Show(ex.Message); } } }

Can you please help in this?

Hi, if I understood you want to use a USB dongle or a internal Bluetooth of a PC for receive the data from the HC-05 device.
I never used the library 32feet.NET so I don't think that I can help you.
what kind of exception you have?

hey what is the exact AT Command for a master device to search its near by SLAVE device?? is it AT+INQ??

Yes is AT+INQ

this command responds: +INQ:<Bluetooth address>,<device type>,<signal intensity>

The HC05 Test Software would be great tool but it doesn't send out the required CR+LF characters at the end. You can easily check this with any terminal program. This program can only be used with the HC06 that doesn't require the CR+LF characters at the end.

Hi Ernie, Yes my software doesn't send the CR+LF characters but the Bluetooth HC05 works without the CR+LF characters.

In next few days I will publish the new HC05 Test Software v1.2 with the possibility to add to the end of message the following characters None/LF/CR/CR+LF.

I'm looking forward to the new version.

From the HC-05 User Instructions: "Command structure: all command should end up with “\r\n” (Hex: 0X0D X0A) as the terminator."

I tried without, using a terminal program and the modules that I have, definitely need the CR+LF characters appended.

I understood, you are using my HC05 Test Software but not my mbed firmware that appends the "\r\n" character.

I uploaded the new version, give me a feedback. Thanks
Edoardo

Hi All,

I have the Wireless Buzzband BT-88 which I'd like to trigger using the HC-05 combined with the Arduino. The Buzzband BT-88 device name is 'WATCHDOG' and its default pairing code is '0000'. Does anyone have any ideas where to start? Any help is much appreciated

Thanks.

please tell me how can i use HC-05 with embed 1768 to receive the data from IMU LSM9DS1

Hi there...! Im trying to do a project where I use a Geiger Counter to measure radiation on an autonomous electric vehicle. So by the time it drives around and meets objects that contain radiation as soon as it detects them I want it to wireless send the data on my android phone. Would that be possible using that?Please let me know. May I ask for an email as well? Thank you.

Hi Alexandros,

First you need to receive the Geiger Counter datas with mbed.
Then you can send the datas to a phone over bluetooth.

Probably a problem is the maximun working distance of this bluetooth.

Hello . I'm using HC05 and i need to send data(any text value) from my Android app to device . but i don't know how to pass data from App to this device . Any method or command you can suggest ?
