BlueTooth between Arduinos?

Post by sketchy »

Just checking before I buy two BlueTooth Breakout boards. My scenarios has many sensor nodes. The sensor nodes talk to a Base Station. I'm looking at putting BTLE as the communications RF between a sensor node and a Base Station. I assume I can use Adafruit_BLE_UART.h in both the sensor node and Base Station sketches and communications between the two will be fine. Ultimately, I might have about 32 nodes communicating with a Base Station. The nodes will periodically go to sleep then wake up. The Base Station will request readings from each node. I don't think this should be an issue either given BTLE's addressing scheme. Just wanted to verify.

Thanks very much. If all is ok, I'll go ahead and order 2.

I'm afraid the Bluetooth breakouts can't connect to each other.

Bluetooth uses a master/slave device model. The master controls all communication, and the slaves just do what the master tells them. The BTLE chips on the breakout are slave devices, so they can't initiate connections with other devices.
