TinyRF on ESP-12F about tinyrf

[lpriemis]

After updating the Library. It seems to work. Now it crashes on MQTT.

I'm going to have a look with a different MQTT client.

@lpriemis You need to add IRAM_ATTR before ISR functions for the ESP.

To do that you should edit TinyRF_RX.cpp and add that to line 211 as follows:
IRAM_ATTR void interrupt_routine(){...

If that didn't work try using another pin for RX, for example if using pin 4:
void setupReceiver(4);

This library was written with only Arduino as receiver in mind but I know at least one person who has used it with ESP without issues. I plan to add support for ESP in the next release so people won't have to do this edit manually.

@pouriap You are right. It worked.

Unfortunatly now i get the reboots as soon as i want to connect to WIFI ("ESP8266WiFi.h").

Does the example sketch work?

[lpriemis]

Yes it works like a charm right up till the point i try to connect to WIFI ( WiFi.begin(ssid, password); ). Then it start rebooting:

#include "TinyRF_RX.h"
#include "ESP8266WiFi.h"


// you can only use pins that support external interrupts
// in Arduino Uno this is pins 2 and 3
int rxPin = 4;


char ssid[] = "XXXXXXXXXX";
char password[] = "XXXXXXXXXXX";

void setup(){
  Serial.begin(115200);
  setupReceiver(rxPin);
  WiFi.begin(ssid, password);
}

void loop(){

  const uint8_t bufSize = 30;
  byte buf[bufSize];
  uint8_t numLostMsgs = 0;
  uint8_t numRcvdBytes = 0;

  // number of received bytes will be put in numRcvdBytes
  // if sequence numbering is enabled the number of lost messages will be put in numLostMsgs
  // if you have disabled sequence numbering or don't need number of lost messages you can omit this argument
  uint8_t err = getReceivedData(buf, bufSize, numRcvdBytes, numLostMsgs);

  // the receiver has a circular FIFO buffer
  // if getReceivedData() isn't called frequently enough then older messages will get overwritten
  // so make sure the frequency at which you send messages in your tx code is slower than the frequency
  // at which you call getReceivedData() in your rx code to prevent that
  // specially when you are using sendMulti()
  // duplicate messages that are sent using sendMulti() will stay in the buffer until you read the first one
  // you can change the buffer size in settings.h

  if(err == TRF_ERR_NO_DATA){
    return;
  }

  if(err == TRF_ERR_BUFFER_OVERFLOW){
    Serial.println("Buffer too small for received data!");
    return;
  }

  if(err == TRF_ERR_CORRUPTED){
    Serial.println("Received corrupted data.");
    return;
  }

  // if sequence numbering is enabled and you use the sendMulti() function for sending a message
  // multiple times then getReceivedData() will return TRF_ERR_SUCCESS only once
  // all the duplicate messages will be automatically ignored
  // this means all you need to do is check if the return code is TRF_ERR_SUCCESS
  // these are non-repeated, crc-valid messages
  if(err == TRF_ERR_SUCCESS){
    Serial.print("Received: ");
    for(int i=0; i<numRcvdBytes; i++){
      Serial.print((char)buf[i]);
    }
    Serial.println("");

    if(numLostMsgs>0){
      Serial.print(numLostMsgs);
      Serial.println(" messages were lost before this message.");
    }
  }
  
}

A few things to try:

• Make 100% sure that the ESP has enough power, most ESP issues are power related. Try another power source, different wires, etc.
• Wait until WiFi is connected:

WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED){
  delay (500);
  Serial.print (".");
}

• Go to Tools -> Erase Flash and select Sketch + WiFi Settings and change your setup code like this:

void setup(){
  Serial.begin(115200);
  setupReceiver(rxPin);
  WiFi.mode(WIFI_STA);
  WiFi.setAutoReconnect(true);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED){
    delay (500);
    Serial.print (".");
  }
}

• Try changing the baudrate of Serial
• Try connecting to WiFi first before calling setupReceiver() like so:

void setup(){
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  setupReceiver(rxPin);
}

• Try another pin for RX
• Try using another version of ESP8266 core

Great news,

I got it to work with ArduinoMqttClient.

So i guess updating ESP8266WiFi and changing to ArduinoMqttClient. Did the trick.

Now i have a sensor with a Attiny13 which cusomes about 10uA in sleep mode and about 1mA during the sensing part (25ms). I guess this can keep running for ever on a 18650 cell. ESP works like a bridge to put the received message on a generic MQTT broker so my Home Assistant can pick it up. Now i'm set to build any type of sensor i want in my house with a Attiny and a 433Mhz transmitor.

Just to be complete, this are my arduino settings for uploading the sketch to the ESP12F:

Thanks for the very good support. To be honest posting an issue here was a long shot i didn't think you would have a look at it after so much time putting this Library online. Certainly not within hours :-)

That's great.
Glad I was able to help.
