Node - Gateway communication issues
-
I have a test setup comprised of two 3.3V Arduino Pro Minis, each hooked to an RFM69HW 433MHz module.
I configured the Temp/RH node to send the readings every second to the gateway. All works fine until either I reset the gateway, or some hickup occurs and then the remote node stops sending messages even if I reset the gateway, or reinstall its sketch. Looks like if it can't reach the gateway it enters some fault mode and stays there until I reset it.Here's the node's sketch
#define MY_NODE_ID 2 #define MY_DEBUG #define MY_RADIO_RFM69 #define MY_RFM69_FREQUENCY RF69_433MHZ #define MY_IS_RFM69HW #define MY_RFM69_NETWORKID 100 #include <MySensors.h> #include <SPI.h> #include <Wire.h> #include "Adafruit_Si7021.h" #define COMPARE_TEMP 0 unsigned long SLEEP_TIME = 1000; Adafruit_Si7021 sensor = Adafruit_Si7021(); MyMessage msgTemp(1, V_TEMP); MyMessage msgRh(2, V_HUM); float lastTemp; float lastRh; boolean requestACK = false; void setup() { delay(100); sendSketchInfo("Temperature/RH Sensor N1 RFM69", "1.1"); sensor.begin(); present(1, S_TEMP); present(2, S_HUM); } void loop() { unsigned long startTime = micros(); lastRh = sensor.readHumidity(); lastTemp = sensor.readTemperature(); send(msgTemp.set(lastTemp,2)); send(msgRh.set(lastRh,2)); unsigned long endTime = micros(); unsigned long txTime = endTime - startTime; Serial.print("Time awake: "); Serial.print(txTime/1000); Serial.println("ms"); sleep(SLEEP_TIME); }
And here's the gateway sketch

The libraries are untouched and I'm using Arduino IDE 1.6.13 with the AVR Boards version 1.6.15.

I don't even know what's the meaning TSP and TNR.

It seems that adding:
#define MY_PARENT_NODE_IS_STATIC
is of some help, however I did noticed a large increase in TX time even though i set
boolean requestACK = false;
So the whole protocol appears to resemble more with TCP rather than UDP. All things considered I believe the remote battery powered nodes should be able to successfully recover from a temporarily gateway failure without increasing their TX time substantially. The TNR state is excellent when it comes to TX time during gateway failure but it misses a mechanism to automatically recover from this state once the gateway is back. ** MY_PARENT_NODE_IS_STATIC** allows for recovery but at the expense if doubling the TX time. So in production you either manually reset all sensor nodes after a gateway failure, or you take immediate action to minimize the impact on the sensors batteries.
