hi, I am familiar with blynk and have already used it. I could imagine the blynk routine causing delays. but normally the interrupt routine for the reception runs in parallel. which library do you use to receive the sensors? regards
The library is yours SmartRC-CC1101-Driver-Lib. I wonder if is it a Blynk problem or maybe somekind of interferation between Nodemcu, power Supply and CC1101. Nevertheless if there is no Wifi in Arduino Nano everything is OK.
I actually meant a library like rc-switch.
Of course the Rc-switch is also used.
can you show me your sketch?
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <RCSwitch.h>
#include <ELECHOUSE_CC1101_SRC_DRV.h>
RCSwitch mySwitch = RCSwitch();
BlynkTimer timer;
char auth[] = "xxxx";
int pin; // int for Receive pin.
void rf433 () {
if (mySwitch.available()) {
if (mySwitch.getReceivedValue() == 13270148) {
//delay (100);
Blynk.virtualWrite(V1, 1);
Blynk.virtualWrite(V2, (ELECHOUSE_cc1101.getRssi()));
}
else if (mySwitch.getReceivedValue() == 13650702) {
//delay (100);
Blynk.virtualWrite(V3, 1);
Blynk.virtualWrite(V4, (ELECHOUSE_cc1101.getRssi()));
}
delay (100);
Serial.print("Received ");
Serial.print( mySwitch.getReceivedValue() );
Serial.print(" / ");
Serial.print( mySwitch.getReceivedBitlength() );
Serial.print("bit ");
Serial.print("Protocol: ");
Serial.println( mySwitch.getReceivedProtocol() );
Serial.print("RSSI: ");
Serial.println(ELECHOUSE_cc1101.getRssi());
mySwitch.resetAvailable();
}
else
{ Blynk.virtualWrite(V1, 0);
Blynk.virtualWrite(V3, 0);
delay (100);
}}
void setup() {
Blynk.begin(auth, "xxx", "xxxx");
timer.setInterval(2000L, rf433 );
Serial.begin(9600);
#ifdef ESP32
pin = 4; // for esp32! Receiver on GPIO pin 4.
#elif ESP8266
pin = 4; // for esp8266! Receiver on pin 4 = D2.
#else
pin = 0; // for Arduino! Receiver on interrupt 0 => that is pin #2
#endif
if (ELECHOUSE_cc1101.getCC1101()){ // Check the CC1101 Spi connection.
Serial.println("Connection OK");
}else{
Serial.println("Connection Error");
}
//CC1101 Settings: (Settings with "//" are optional!)
ELECHOUSE_cc1101.Init(); // must be set to initialize the cc1101!
//ELECHOUSE_cc1101.setRxBW(812.50); // Set the Receive Bandwidth in kHz. Value from 58.03 to 812.50. Default is 812.50 kHz.
//ELECHOUSE_cc1101.setPA(10); // set TxPower. The following settings are possible depending on the frequency band. (-30 -20 -15 -10 -6 0 5 7 10 11 12) Default is max!
ELECHOUSE_cc1101.setMHZ(433.92); // Here you can set your basic frequency. The lib calculates the frequency automatically (default = 433.92).The cc1101 can: 300-348 MHZ, 387-464MHZ and 779-928MHZ. Read More info from datasheet.
mySwitch.enableReceive(pin); // Receiver on
ELECHOUSE_cc1101.SetRx(); // set Receive on
}
void loop() {
Blynk.run();
timer.run();
}
What is strange, that serial printing improves the situation. When I remove all the serial printings it is getting worse
Hello
I'm writng a code for small security system, with some commercially available PIR 433 Mhz sensors (solid code) and CC1101 with ESP8266 Nodemcu as a central reciever. I use the Blynk as a platform. In Blynk it is recommended to use timer function to create loop that controls incoming 433 signals.
I found unusual behavior of the system, when I try to integrate several PIR sensors. The Rx range is very short, about 2 meters. When I use Arduino Nano with simple default code without Blynk I can integrate PIR sensors without any problem with Rx range.
Is Blynk generate the problem with communication range ?
