Another option was to use a Bluetooth SM-HC-08 module, and connect it directly to the board for testing the data sendings first.
Group Assignment:
- Send a message between two projects.
Individual Assignment:
- Design, build, and connect wired or wireless node(s) with network or bus addresses.
For this assignment my aim is to build a bluetooth shield to send the data read by the sensors (temperature, humidity and wind/rain gauge) on my weather station device for the final project.
I am choosing bluetooth connection over a wifi network to simplify its system as the device is thought to be used in rural areas where internet access is not very common. Therefore, the data sending so far will be adapted for communications between devices with bluetooth connections only.
taking this tutorial as a reference
First for designing my communication shield board I will be using the Bluetooth 4.2 Low Energy Module Shield HM-08 (which is the one on the Lab). I prefer to design the board from zero to create a new one which also includes the pin connections for the LCD Display (as an output shield board).
Another option was to use a Bluetooth SM-HC-08 module, and connect it directly to the board for testing the data sendings first.
I am taking as a reference this Bluetooth module board called hello.RN4871.ftdi BLE board similar to this HM-11 Bluetooth module. The board should look like this:
This is the circuit's schematics:
And these are the png files:
I milled one PCB including the next elements:
For the group assignment I will need to test the data sending between my board and other Bluetooth boards in the group.
