Multiple messages to same node, seems to miss one.

@electrik yes it is available
Edit: Sorry, seems like it is not available on esp8266.

[electrik]

@mfalkvidd That is good to hear. What should I do to have that enabled?

[CrankyCoder]

@yveaux is this something that could be a problem at the repeater and the node itself? I don't think it's the gateway as the messages aren't coming in, it's being delivered to the node.

[mfalkvidd]

@electrik It should have been sufficient to follow the documentation, but it seems like MY_RX_MESSAGE_BUFFER_FEATURE is only available for atmega328 (or perhaps also for SAMD and Linux/Raspberry Pi but definitely not for esp8266).

I have created an issue to clarify the documentation.

Thanks to @Yveaux for notifying me.

[electrik]

@mfalkvidd all right thanks. Is there an alternative to avoid losing messages on an ESP8266 MQTT gateway?

[Yveaux]

@electrik decrease the message rate or the number of messages sent in bursts

[electrik]

@yveaux What is a rate that is still expected to be possible? Or, how often is the buffer from the NRF emptied?

[Yveaux]

@electrik that's a tough one... Every time loop() executes, or if you call eg wait() the queue is emptied.
So it all depends on what you do in your sketch.

[electrik]

@yveaux so by calling wait () a couple of times in the loop, it will be processed more often. I will try that, thanks

[electrik]

@Yveaux do you know if there are plans to support this buffering on the ESP8266 or the ESP32? Is it all related to SoftSPI?

[Yveaux]

@electrik the problem is the arduino port, not the mySensors stack. Last time I checked the issue on GitHub was still unresolved...

[Yveaux]

@yveaux This seems to be the original issue, which is closed: https://github.com/esp8266/Arduino/issues/1943
That sounds hopeful, but no time to check it right now...

[electrik]

@yveaux Did you find some time already to have a look at this? :-)
