Hello,
I am useing a power meter that every second sends a data packet at 9600 baud via a serial interface. The YUN receives this data via software serial. TX is not used.
The received data are sent in one case directly to the Console. In the other case I use the YunsServer to request the data via REST query.
After a few cycles the Bridge behaves incorrectly (on both scenarios).
When using the console, the transmission after a few blocks aborts.
After some requests the YunServer provides only an empty response.
A certain success was achieved when I strictly separate the code of the serial side from the code of the Bridge.
After the error has occurred, there are also problems when transferring a new sketch.
Often, a reset is necessary.
But it works never really good.
Are there any known problems?
Are there any solutions?
My IDE ist 1.5.5-R2.
The Path with the "python -u" is applied
The power meter ist sending the data every second.
Update: After waiting some minutes the transmission recovers from his "sleep". But only for a few transmissions.
The code:
#include <SoftwareSerial.h>
#include <Bridge.h>
#include <Console.h>
//Buffer size from 64 to 256 increased
SoftwareSerial mySerial = SoftwareSerial (8,9); // RX, TX
String inputSerial = "";
char rChar = ' ';
long cntr = 0;
bool store = false;
void setup() {
Bridge.begin();
Console.begin();
while(!Console);
inputSerial.reserve (600);
mySerial.begin(9600);
Console.println ("Success");
}
// ****************************************
// Main Loop
// ****************************************
void loop() {
// Read and transmit
while ((mySerial.available() > 0) && store) {
rChar = (char) (mySerial.read() & 0x7F);
inputSerial += rChar;
if (rChar == '!') {
store = false;
Console.println (inputSerial);
inputSerial = "";
}
}
// Read, but don not transmit
while ((mySerial.available() > 0) && !store) {
if ((char) (mySerial.read() & 0x7F) == '!') {
cntr++;
if (cntr > 2) {
store = true;
cntr = 0;
}
}
}
delay (20);
}
