Bluno to Bluno

Does anyone have a basic Arduino sketch for a Bluno to Bluno connection? I was hoping to test the connection between two of my Bluno Nanos with a simple Arduino sketch that sends something like the blink command wirelessly, but I've been having issues with the one I've created.

Great! and thx for following up. Leff

2016-05-26 20:44:52 Thanks, I think I finally got it. I did "uint8_t" instead on both sides to create byte information for my three LEDs. Everything seems to be functioning as I would like it to, now. Now I just have to change the code to send char to CAN. sartbaug

2016-05-26 02:30:39 I would say I'm just trying to send commands. When I push a button on one Bluno, I want the other one to read the button press and turn on an LED or send a message. I seem to have the devices up and running now. I have three buttons connected to the Master Bluno that activate three different LEDs on the Slave Bluno. My issue was with the Serial.write and Serial.read commands in Arduino IDE and my confusion about the Link LED. sartbaug

Sorry, may I confirm your intention to do wireless programming or just to send command with the two Bluno nanos? Leff

2016-05-24 21:31:34 As a follow up, I apparently have a bad Link LED on the Central Bluno. It's reading 3.3V across it currently, but the LED isn't on. So both of their Link LEDs should be on. When I press the button on Central Bluno to send the message, the Central Bluno's RX LED flashes and the Peripheral Bluno's TX LED flashes. This seems backwards to me, but I don't know what I'm doing wrong. sartbaug

2016-05-24 20:45:29 Yes, I followed that guide. After I updated those and tried to run a program the one I set to peripheral had the Link LED on, but not the Bluno set to Central. I'm not sure if that is how it's supposed to appear or not, but when I try to send the blink command wirelessly with a button connected to the Central Bluno. The RX light blinks once on the Central device and the Peripheral device does nothing. sartbaug

If you establish a connection between two nanos, it is easy to send something like the blink command wirelessly. So do you make a connnection successfully between two nanos? To make a wireless programming via BLE, you can check the following link
