BLE communication between Arduino and Rpi2

Projects General Guidance

I have an rpi2 with a serial-uart bluetooth hm10 connecting to a bluetooth enabled relay board. I use this code:

#!/usr/bin/env python
import serial
ser = serial.Serial(
        port='/dev/serial0',
        baudrate=9600,
        parity=serial.PARITY_NONE,
        stopbits=serial.STOPBITS_ONE,
        bytesize=serial.EIGHTBITS,
        timeout=1
)

print "Serial is open: " + str(ser.isOpen())

print "Now Writing"
ser.write("AT+CONNL")
print "Did write, now read"
x = ser.readline()
print "got '" + x + "'"

at some point I used a different ser.write command to connect to the ble module, i think it was the AT+macaddress command.

Anyway, that is used to send&get commands to the relay board with another script which is run 2x a day at about 12 hour intervals. Its just an rpi2-serialBLE to ble-relay board connection.

I want to add a flowmeter that will use a bluetooth to send data to the rpi. Ill probably want to have a debug arduino script to send data constantly for debugging purposes at first but the real script later will only have to send the data over ble to the rpi2 once at the end of the day.

Im using this board called Bluno nano: Bluno Nano

It basically has ble so Im good. What I want is to figure out how to connect and send data to the rpi2 from it, without disturbing the current setup of ble. I found this article:

http://blog.whatgeek.com.pt/2015/09/bluetooth-communication-between-raspberry-pi-and-arduino/

which has some preliminary steps like:

  1. bluetooth bluez-utils bluez-alsa
  2. gpasswd -a pi bluetooth
  3. hciconfig hci0 up
  4. hcitool scan
  5. bluez-simple-agent hci0 98:D3:31:50:0A:CE
  6. bluez-test-device trusted 98:D3:31:50:0A:CE

The ble-relay board I have already is paired and trusted to my rpi2 I guess. Will doing this with the new bluno nano disturb my existing connection, it shouldnt, should it?
