I am running into issues creating a passthru sketch for Bluetooth->ISBD.
I can get the BlueSMiRF pass thru to work (From Bluetooth device through ardy to Serial Monitor, and back), and I can get the ISBD module to work (From Serial Monitor through ardy to ISBD module, and back), but when I try and merge the code, the ISBD module gets stuck trying to find the modem. The funny thing is, even if I don't actually do anything with the bluetooth, just declare and create the port, the ISBD modem still gets hung up. If I take the same code and comment out all of my bluetooth stuff, the ISBD modem works again.....
Bluetooth Pass Through Stand Alone Code (this works):
#include <SoftwareSerial.h>
int bluetoothTx = 8; // TX-O pin of bluetooth mate, Arduino D8
int bluetoothRx = 7; // RX-I pin of bluetooth mate, Arduino D7
SoftwareSerial bluetooth(bluetoothTx, bluetoothRx);
void setup()
{
Serial.begin(9600); // Begin the serial monitor at 9600bps
bluetooth.begin(115200); // The Bluetooth Mate defaults to 115200bps
bluetooth.print("$"); // Print three times individually
bluetooth.print("$");
bluetooth.print("$"); // Enter command mode
delay(100); // Short delay, wait for the Mate to send back CMD
bluetooth.println("U,9600,N"); // Temporarily Change the baudrate to 9600, no parity
// 115200 can be too fast at times for NewSoftSerial to relay the data reliably
bluetooth.begin(9600); // Start bluetooth serial at 9600
}
void loop()
{
if(bluetooth.available()) // If the bluetooth sent any characters
{
// Send any characters the bluetooth prints to the serial monitor
Serial.print((char)bluetooth.read());
}
if(Serial.available()) // If stuff was typed in the serial monitor
{
// Send any characters the Serial monitor prints to the bluetooth
bluetooth.print((char)Serial.read());
}
// and loop forever and ever!
}
ISBD Pass Through (Bluetooth Stuff commented out, this works, but you need the IridiumSBD.h and the IridiumSBD.cpp files. I can post them if needed):
#include <SoftwareSerial.h>
#include <IridiumSBD.h>
#define DIAGNOSTICS true // Change this to see diagnostics
//int bluetoothTx = 8; // TX-O pin of bluetooth mate, Arduino D2
//int bluetoothRx = 7; // RX-I pin of bluetooth mate, Arduino D3
int ibsdTx = 9;
int ibsdRx = 10;
//SoftwareSerial bluetooth(bluetoothTx, bluetoothRx);
SoftwareSerial IridiumSerial(ibsdRx,ibsdTx);
IridiumSBD modem(IridiumSerial);
void setup()
{
int signalQuality = -1;
// Start the serial ports
Serial.begin(19200);
//while (!Serial);
//Setup Bluetooth
//bluetooth.begin(115200); // The Bluetooth Mate defaults to 115200bps
//bluetooth.print("$"); // Print three times individually
//bluetooth.print("$");
//bluetooth.print("$"); // Enter command mode
delay(100); // Short delay, wait for the Mate to send back CMD
//bluetooth.println("U,9600,N"); // Temporarily Change the baudrate to 9600, no parity
// 115200 can be too fast at times for NewSoftSerial to relay the data reliably
//bluetooth.begin(9600); // Start bluetooth serial at 19200
// Setup the Iridium modem
IridiumSerial.begin(19200);
modem.setPowerProfile(1);
if (modem.begin() != ISBD_SUCCESS)
{
Serial.println("Couldn't begin modem operations.");
exit(0);
}
// Check the signal quality (optional)
int err = modem.getSignalQuality(signalQuality);
if (err != 0)
{
Serial.print("SignalQuality failed: error ");
Serial.println(err);
exit(1);
}
Serial.print("Signal quality is ");
Serial.println(signalQuality);
Serial.println("Enter commands terminated by Carriage Return ('\\r'):");
}
void loop()
{
if (Serial.available())
IridiumSerial.write(Serial.read());
if (IridiumSerial.available())
Serial.write(IridiumSerial.read());
}
#if DIAGNOSTICS

My first thought was the rockBLOCK wasn't getting enough power, so I supplied it from a different source and still ran into the issue. Do you think it could be an issue with having two software serial ports, and a hardware serial port open at the same time? Would bluetooth over SPI potentially resolve this?
