ESP8266 gateway and sensor node not talking - noobie

Fabien

With the last git developpement it works. except when a node start presentation, gateway reboot. And sometimes it reboots randomless.
node is a sensebender with MySensors 1.6 and gateway with 1.6 too.
Important : You have to define MY_RF69_IRQ_NUM = MY_RF26_IRQ_PIN on ESP8266

#define MY_RADIO_RFM69
#define MY_RFM69_FREQUENCY   RF69_868MHZ
#define MY_RF69_IRQ_PIN 15
#define MY_RF69_SPI_CS 2
#define MY_RF69_IRQ_NUM 15

I don't try with other timeout values.

hek

Ok, great. We need to increase timeout then.

Fabien

@hek Yes and perhaps a feature to set MY_RF69_IRQ_NUM = MY_RF26_IRQ_PIN when using ESP8266. Do You want to test other timeout values ? Is it critical ?

hek

@Fabien said:

MY_RF26_IRQ_PIN

I cannot find this defined anywhere...

Fabien

sorry MY_RF69_IRQ_PIN ...

Fabien

Work with 51ms timeout with my config. I set 60ms to be "secure"

@hek said:

Ok, great. We need to increase timeout then.

Better add a yield() call in those blocking wait loops.
When quiclkly looking over the code of the RF69 driver, the RFM69::initialize call could in theory block for 1.5 sec...
That's a watchdog reset waiting to happen!

hek

Yep,

This is working great !

I am seeing something similar with RFM69 (specifically RFM69CW) and ESP8266. I have build an ESP8266 gateway based on the GatewayESP8266 sketch and this is what I changed

#define MY_RADIO_RFM69
#define MY_GATEWAY_ESP8266
#define MY_RFM69_FREQUENCY   RF69_868MHZ
#define MY_RF69_IRQ_PIN 4
#define MY_RF69_SPI_CS 15
#define MY_RF69_IRQ_NUM 4

I build a sensor node with the DallasTemperatureSensor sketch on an Arduino Mini Pro and defined

#define MY_RADIO_RFM69
#define MY_RFM69_FREQUENCY   RF69_868MHZ

When I start up the gateway I see

0;255;3;0;9;Starting gateway (RRNGE-, 2.0.0-beta)
0;255;3;0;9;Radio init successful.

So far so good - I assume all the radio wiring is OK, since the radio init is successful

On the sensor node I see

Radio init successful.

As soon as the sensor node is started the ESP8266 crashes with a WDT reset

The libraries are 2.0 beta as from a few days ago. I consider the power to the ESP8266 to be OK, since I use the same for en NRF24 based gateway and also for several other ESP modules.

From the thread I understand that known issues should be fixed in the current beta. Any ideas on how to move on?

Yveaux

@chrille Try adding the following line to your setup() function:

ESP.wdtDisable();

It should disable the (software) watchdog on ESP. See if it continues, or if it will now just hang.

chrille

@Yveaux Just tried that. The change removed the watchdog message and the stack trace, but the module still reboots

chrille

...I also tried to change TIME_OUT in rfm69.cpp to 500 as suggested by Fabien. Doesn't make any difference

Yveaux

@chrille said:

the module still reboots

Probably the hardware watchdog kicks in then...

chrille

@Yveaux I did some further tests and it may be related to the inclusion mode feature. At least disabling this makes things more stable - but I still haven't got the radio side working reliable. When this is working I will go back to the gateway and see if I can find out what triggers the crash

chrille

@Yveaux I think I have narrowed down the issue now to this code in RFM69.cpp

void RFM69::sendACK(const void* buffer, byte bufferSize) {
debug(PSTR("RFM69: void sendACK\n"));
  byte sender = SENDERID;
  debug(PSTR("RFM69: sendACK - entering while()\n"));
  while (!canSend()) receiveDone();
  sendFrame(sender, buffer, bufferSize, false, true);
}

(The debug lines are added by me)

Most of the time the WDT kicks in, after logging "entering while()" - occasionally it will reach sendFrame() and log a "read: " line but then the WDT kicks in when it gets to the while() loop again.
sendAck is called from sendFrame, that disables interrupts, by calling select()

With a bunch of additional debug turned on, this is what I get on the console

Yveaux

@chrille I'm not familiar with rfm implementation, but you could try adding a call to yield() inside the while loop.

chrille

@Yveaux Thank you very much. This seems to have fixed the issue now!
