Speed / baudrate of the BLE connection?
I'm using the UART over BLE example. It seems there is a "delay" somewhere between sending packets. Is it possible to make the transmission faster? Currently it looks like the Tx packets are saved in a buffer and are send periodically. Here is the code:
#include <Arduino.h>
#include "BLESerial.h"
#include "variant.h"
BLESerial bleSerial;
int32_t count = 5;
#define LED_DELAY 10
void setupBLE() {
bleSerial.setLocalName("UART over BLE!");
bleSerial.begin();
}
void printBLE() {
if (bleSerial) {
bleSerial.println(count);
}
}
void setup() {
Serial.setPins(PIN_SERIAL_RX, PIN_SERIAL_TX);
Serial.begin(115200);
Serial.println("Hi Pooya from nRF52832!");
pinMode(BLUE_LED, OUTPUT);
pinMode(GREEN_LED, OUTPUT);
setupBLE();
}
void loop() {
if (count > 0) {
digitalWrite(BLUE_LED, HIGH);
delay(LED_DELAY);
digitalWrite(BLUE_LED, LOW);
delay(LED_DELAY);
digitalWrite(GREEN_LED, HIGH);
delay(LED_DELAY);
digitalWrite(GREEN_LED, LOW);
delay(LED_DELAY);
}
count++;
printBLE();
}
Note that the transmission delay doesn't seem to be around 4*LED_DELAY but much longer ~800ms.
