[edit] Overview
The radino rf serial bridge is an example for a uart bridge over radio.
Currently implemented is the functionality following radino wireless chips:
- CC1101 at 868.3 MHz (radino CC1101, radino32 CC1101)
- CC1101 at 922.5 MHz (radino CC1101, radino32 CC1101)
- CC1101 at 433 MHz (radino CC1101, radino32 CC1101)
- RF69 at 433 MHz (radino RF69)
- RF233 at 2.4 GHz (radino RF233)
[edit] Configuration
At the section "Main configuration" within the sketch the used hardware has to be configured.
Which serial interface to bridge over wireless
#define BRIDGED_SERIAL_SELECTION BRIDGE_HWSERIAL #define BRIDGED_SERIAL_SPEED 9600
Which wireless chip is used
#define WIRELESS_HARDWARE CC1101_868_38400_p100
If and which pin is used to enter command mode
#define CONFIG_BUTTON_PIN 5
If TX and RX LEDs should display activity on the serial interface
#define USE_SERIALLEDS true
Define bigger buffers for the radio communication is necessary. Note that this only makes sense on radino32 modules with its bigger memory.
//#define MY_RADIO_BUFSIZE 4096 //Overide Buffer for data received from radio //#define MY_UART_BUFSIZE 4096 //Overide Buffer for data received from uart
[edit] Usage
- 1 select serial to bridge. Default: HardwareSerial1
- 2 select wireless chip. Default: CC1101 at 868mHz
- 3 Upload the sketch to your radino modules.
- 4 Connect serial hardware to the interface selected in step 1.
- 5 Data received by one module is written out one the other one.
[edit] Command mode
By pulling down the commandModePin the module is put into the command mode, where wireless addressing can be changed.
The module will print the info string
N)wID:00 M)yID:FF T)gtID:FF L)istenBC:1 S)tore P)ing R)eload Q)uit
NwID: Network ID. Only messages from our network are accepted
MyID: Our ID. Messages targeted at our ID are received. Is used as srcId in messages. 0xFF: BroadcastAdress->is not ACKed
TgtID: Targets ID. Messages are sent to this device. 0xFF: Broadcast
ListnBC: Are we accepting messages targeted at the Broadcast ID 0xFF
Commands consisting of up to 3 chars can then be entered.
The chars are shifted in and on '\r' or '\n' the last 3 entered ones are interpreted as command.
Available commands
"nXX": set network ID to XX (Hex) "mXX": set my ID to XX (Hex) "tXX": set target ID to XX (Hex) "lXX": set broadcast listening (Hex) (0->off, else->on) "s": store values to eeprom "r": reload values from eeprom "p": ping and list devices in range "q": exit command mode
Examples
"n2m55\r" -> command "m55" is executed "l0\r" -> command "l0" is executed "sss\n" -> command "s" is executed "qss\n" -> command "q" is executed
Output of the sequence "CommandModePin LOW", "p\r\n", "q\r\n"
Entering command mode N)wID:00 M)yID:FF T)gtID:FF L)istenBC:1 S)tore P)ing R)eload Q)uit > p p: Pinging neighbours ID MyRSSI TgtRSSI FF -30.50 -29.50 OK N)wID:00 M)yID:FF T)gtID:FF L)istenBC:1 S)tore P)ing R)eload Q)uit > q q: Quitting command mode OK
