Help: Some explanation requested regarding NACK

[Omemanti]

Stupid question.. because I use the rfm69. Will the also comply?

[gohan]

Of course not. What version of rfm69 and frequency are you using? Are you sure you got the antenna of the right size?

[Omemanti]

Rfm69w 868mhz , springcoil antenna from ebay.
will test a long single wire right away.

[Omemanti]

Springcoil on the gw, straight line on the node, still the same

[Omemanti]

Thnx for the help so far, Ill let it rest for a while, Im thinking of rebuilding the whole thing..

Where you able to solve this? I am also experiencing a lot of NACKs in my rfm69 network (868mhz)

Nope, not that I can remember.
BTW: I ditched the rfm69 and moved over to the NRF52.

I had exactly the same issue with Rfm69 and latest version of mysensors. The only solution I found is to use the 2.2.0 version. With this everything works perfectly.

I don't know why with latest releases the messages are NACK even if they actually reach the gateway.

@ricmail85 I solved my problem by soldering a cable to the reset pin of the chip and the (in my case) raspberry pi. This or the dupont wires I used were glitchy :D

[ricmail85]

@kiesel thanks for reporting! I've also a Raspberry gateway but I left the Rfm69 reset pin unconnected. How did you connect it?

[kiesel]

@ricmail85 sorry for the late reply. I soldered it to a free pin on the pi and reconfigured the gateway.

Use this as part of your configure

--extra-cxxflags="-DMY_RFM69_RST_PIN=29"

If you connected to pi pin 29.
