Problem transmitting bytes via newsoftserial

Using Arduino Programming Questions
1

Hello,

I'm using the following for example to transmit an array from one arduino nano to another using an RF transceiver (set at 9600 baud) using newsoftserial on pins 4,5 on both:

// transmitter
char tx_data[13] = {0x02,0x02,num_1,num_2,num_3,num_4,num_5,num_6,num_7,num_8,0x02,0x02,0x00};
transceiver.print(tx_data);

// receiver
if(transceiver.available()) {
    int index = 0;
    byte response[13];
    while(transceiver.available() > 0) {
      response[index] = transceiver.read();
      index++;
    }
}

Each of the "num_x" is a dynamic value between 0-254. I had to put a leading/trailing "0x02,0x02" so on the receiver I can sort of do rx validation as too often there is junk data being received (possibly interference).

While this method works, the problem is I can't transmit faster than a 150 second delay between transmissions otherwise the receiving arduino doesn't read it for some reason.

I know there is limitations of speed at 9600 baud, but I'm wondering if anyone knows of a better way to send an array like that where it can send a bit quicker.

Any help would be appreciated.

While this method works, the problem is I can't transmit faster than a 150 second delay between transmissions otherwise the receiving arduino doesn't read it for some reason.

I would not consider anything that requires a 2 and a half minute delay between transmissions as working, for any definition of working.

This could be a hardware problem, an interference problem, or a software problem on the sender or receiver. Determining where the problem is based on a code snippet on the sender is not possible.

but I'm wondering if anyone knows of a better way to send an array like that where it can send a bit quicker.

You mean besides the obvious one of increasing the baud rate? Sending an array one byte at a time is the fastest way to send data. It isn't, obviously, possible to simultaneously transmit multiple bytes.

What happens if you hook the sending end up to a serial terminal? Do you still have the problem?
