Note that while the bluetooth connection works with ios/android phones, you need to purchase a bluetooth 4.0 dongle or another BLE device to connect Bluno to your pc/laptop running...

Hello Neil,
I am having the same problem you had. Unable to upload any sketches. Are you able to help or advise me here? Thanks.

Hi, can someone link me the smallest battery that can use with this board? Thank you

I want to know pin numbers that bluetooth module is connected to Arduino in. I meant TX, RX pins.

Hi,
You can try using AT command in code.

Hi, My bluno and ble link keep disconnecting, can you please help me solve that? I have to constantly put the at commands to give it the right settings each time i switch them on and a lot of times even then they dont connect.

Yes, it is possible. You can do some function after determine the serial por received the signal.

Is it possible to read the state of the "link" and "pair" leds in an Arduino sketch? I'm trying to trigger an action in my sketch when the linked device (Android phone) goes out of range.

Can 2 Blunos be paried to eachother? I need to transmit GPIO between 2 Bluno devices connected over BLE

I have an Arduino Uno with a Xbee V1.4 shield and a BLE-Link V1.1. I would like my Arduino Uno to communicate with a Raspberry pi 3 model B in BLE. Is it possible?

Done, but the problem was not there.
I realized the issue probably is in the UART speed of the CC2540.
The speed programmed with AT+UART is not "activated" until the USB CDC is connected. If the USB is not connected the UART baud rate is 9600 by default. So I had to use Serial.begin(9600).

I wrote a simple code that send via bluetooth a string in the loop() rountine using Serial.print, but no data is sent until I connect Bluno to pc using USB port and open a terminal like PuTTY.
How can I send data via bluetooth without a pc connected to the board?

How do i find the UUID for my bluno board? I need it for my bluetooth app

BLE 4.0 is different to the old Bluetooth 2.0, you can use app to connect directly.

I was able to communicate by installing Cyanogenmod 12.1 in the phone. Great! So, this is not a hardware limitation. With Cyanogenmod 12.1 (based on Android 5.1) the phone works with Bluno. Great, great!

It took me a very long time to solve this issue because only one Bluno is able to communicate with these phones. Why other Blunos are not working? I don't know (yet). There are no differences in the AT settings from this Bluno to others. Both have v1.96 with AT+SETTING=DEFAULT. I'm using Bluno V2.0. But even when I flash the firmware, the program is not removed neither my settings. Probably there are different settings in the Blunos that I'm not able to check to compare.

How can I clear completely the Bluno?

Thanks!

Why can't not modify BlunoBasicDemo-master in xcode?
Xcode said the app is lock

How to unlock it ?
I am developing the robot with your Bluno board
Thank you

The code --> _service = await GattDeviceService.FromIdAsync(device.Id);

i can get _service information from Bluno in Win 8.1 but i CANNOT get _service from Bluno in Win 10.
The same code but different result??

Hello, i want to develop a desktop application for bluno using c#. do you have any dll that i can use? thanks

Where can I find the external batter pack that is shown in the pictures? Thanks!

Hi!!
I tried the Bluno Basic Demo ... it worked at the beginning but now it doesn't send the message back to the phone.
Apparently it receives the message I write but when I see on the phone it shows symbols ... (the TX LED doesn't lit up) what should I do?

Hi I would like to know if it might be possible for the Bluno to scan other BLE devices around it?
