Suddenly communication between gw & nodes stopped , rebooting pi sometimes solves it

[Huỳnh Minh Khải]

The same issue here and solved by changing my NRF24L01

I have the same problem
pi 3 as gateway ./configure --my-transport=nrf24 --my-rf24-irq-pin=15 --my-gateway=ethernet --my-port=5003

[gohan]

what version are you using?

[A Former User]

@gohan
My last node (8-relay) 2.2.0
my gateway RPi3 git clone https://github.com/mysensors/MySensors.git --branch master
I think I have some other nodes on 2.0.0

[A Former User]

sometimes I see this in my gateway log

Mar 13 17:42:32 MySensorsGW mysgw: !TSF:MSG:SEND,0-0-2-2,s=255,c=3,t=8,pt=1,l=1,sg=0,ft=0,st=NACK:0

[gohan]

@gieljnssns said in Suddenly communication between gw & nodes stopped , rebooting pi sometimes solves it:

mysgw: !TSF:MSG:SEND,0-0-2-2,s=255,c=3,t=8,pt=1,l=1,sg=0,ft=0,st=NACK:0

that looks like the message got lost between the gw and node. You could try moving the node closer or using a repeater halfway. Pls write the gw version since the git-clone is not telling me much

[A Former User]

@gohan
how can I see wich version I'm using?

[gohan]

when GW starts it prints the version in log

[A Former User]

@gohan
version 2.2.0

There is only 4 meter in between my gateway and node.

@huỳnh-minh-khải said in Suddenly communication between gw & nodes stopped , rebooting pi sometimes solves it:

The same issue here and solved by changing my NRF24L01

I've already changed my radio

[gohan]

Do you have a decent capacitor on the radio module? Have you tried a different maker of nrf24 module?

[A Former User]

@gohan
I have these radios https://www.ebay.com/itm/400594940658?rmvSB=true

I've used this adapter plate for my radio https://www.ebay.com/itm/200960749614?rmvSB=true

And there is a capacitor on my radio

[gohan]

I don't like those nrf24 modules as they are 99% fake clones. Once I got some real ones I solved a lot of range issues

[A Former User]

@gohan
Can you give me a link to the real ones?

[gohan]

I bought them on aliexpress from the cdebyte shop. There are a few open topics about real and fake nrf24 if you want to read some more. As a general rule of thumb consider that the genuine nrf24 chip is normally sold around 1.2$ so you can't buy a fully assembled genuine module for less than a dollar.
