Low level routines for controlling a Microchip RN4677 Bluetooth Module.
 
−
Also available in the form of the BL0170 Bluetooth E-block.
 
−
Uses an interrupt to receive characters from the UART and improve reliability, Must be used with a hardware UART channel.
 
  
−
There are component macros in flowcode 8 that allow you to send to and receive information from the Bluetooth component in the form of a string or a single byte. The component needs to be initialised before it can send or receive information, with the ‘Initialise’ macro.
+
Please click here to download the component source project: [https://www.flowcode.co.uk/wiki/componentsource/FC_Comp_Source_EBlocks2_Bluetooth_RN4677_BL0170.fcfx FC_Comp_Source_EBlocks2_Bluetooth_RN4677_BL0170.fcfx]
−
Make sure the Bluetooth component is connected to the right port in flowcode, corresponding to the port it’s connected to on your E-blocks 2 upstream board.

Amount of RAM memory to dedicate to receiving responses and incoming data from the BT module. Default 40 
Fc9-conn-icon.png Connections
Fc9-type-16-icon.png Channel
UART Channel selector Software channels are bit banged using generic I/O pins but are not as reliable as hardware channels. Hardware channels use the selected peripheral on-board the target microcontroller. 
Fc9-type-16-icon.png Baud Options
Baud rate option selector 
Fc9-type-14-icon.png Baud Rate
 
Fc9-type-5-icon.png TX

Fc9-type-5-icon.png RX
Pin to be used for Receive data 
Fc9-type-16-icon.png RX Remap Pin
Allows the hardware receive pin to be configured from a list of available pins based on your target device, 
Fc9-conn-icon.png Simulation
Fc9-type-7-icon.png Simulate Comms
 
Fc9-conn-icon.png Simulation
Fc9-type-7-icon.png Scope Traces
Selects if the scope traces are automatically added to the data recorder window or not. Simulation - draws an approximation of the UART data onto the scope trace. ICT - sets up the scope trace for incoming data and adds UART packet decoding at the correct BAUD. 
Fc9-type-7-icon.png Console Data
Selects if the console data is automatically generated or not
