Bluno nano transfer rate
d.brandonk 2017-03-14 14:12:03 2034 Views4 Replies Does anyone happen to know the max rate at which the bluno nano can transfer bytes through bluetooth because I am running this code
void setup() {
Serial.begin(115200);
}
void loop()
{
for(i = 0; i < 10000; i++)
{
Serial.println(i);
Serial.flush();
}
while(1){}
}
and I am losing a lot of bytes the other end. Or if there is something wrong with my code or if there something that I can be doing better please let me know.
Thanks for the help in advanced,
Brandon

2017-03-18 13:06:44 Okay, thank you. I was not sure if I was doing something incorrectly. But yes, that is about the data rate that I am finding and I implemented similar code to what you suggested to ensure I was not losing data. However, this is a smaller throughput than I would like. I was wondering if you knew whether the size of the throughput is a symptom of the TI CC2540 chip or does if have to do with the clock speed of the bluno nano or anything like that? Because it is just a little confusing when the buad rate is 115200 but is not capable of actually achieving that rate in practice or so it seems. I am just trying to understand the cause of this and any information you have on the subject would be helpful.
Thanks again,

The baud rate of 115200 would be fine. And maybe we can try to add a "delay(100);" to see how its going. Wendy.Hu

Wendy.Hu 2017-03-15 07:29:21 I am trying to max out the throughput of the bluno nano as a slave. Do you recommend a specific buad rate for the ble chip to be set at or a delay between serial port uses or anything like that?

Since the speed from master machine to slave is 4kb/s, and slave to master is 2kb/s. Once the the data is large, which is possible to get the data lost. I would like to suggest you can try to exchange master and slave machine to see what happened.
