nrf24l01 connected to RPi2 as GW

[alexsh1]

Hello,


Does anyone use nrf24l01 connected directly to RPi2 as the gateway?
I have a strange problem. From time to time, all nodes stop reporting to the gateway at the same time. I understand this is not a problem of a node, but a problem with the gateway. Not sure where to look. Rebooting the nodes does not help, I have to reboot the RPi2 to make it work.


See the meter graph below. The circled areas is when there was no signal reception. The same goes for the temperature.

I am using MySensors 1.4 lib - this is the newest for the RPi2 unfortunately.

Any thoughts?

I don't know what the 'nrf24l01' does actually
Seems like a nice cheap chip. What do you use it for?

nrf24l01 is a low energy transceiver board.
Basically, it is my MySensors Gateway (as well as used to switch on/off some relays and Mi-Light bulbs)

i had (have) this problem as well.
thats why i build a queue system in the latest domoticz beta that sends the messages.
But it does not seem to make a difference.....

I am using a sketch that requests a lot of data from domoticz (via V_CUSTOM, see the form post about my lcd sketch)
After some time, the communication stops

I now build an Ethernet gateway, and going to test if this keeps 'alive'

Thanks for confirm it Rob!
The problem is that I spent a lot of time on this and somehow I feel that due to MS version 1.4 (already behind 1.5 stable and 1.6 development) there may be some bugs left. I am not sure this would be supported in the future either.

This is the reason I decided to move on to the ethernet gateway - this runs flawlessly. Unfortunately, this means now that I have to buy an internet switch as all ports on my router are taken. Having 'keep alive' would be great. I like the way Domoticz is logging a serial gateway if it is disconnected.

Hi guys I am having this problem too with a RPi2. Only a reboot will help.
I am using latest dev branch for MYS + DOM.
I have a watchdog script that runs every five minutes on the PI to check if wfi connection drops (pings the router, if no reply, reboot).
I got the script 'from the net' and dont really understand writing pi/linux bash scripts.
Is there a way to write a script that will do the same thing for the radio module/nrf?

Thanks,
Matt

you mean rebooting just the GW instead of rebooting the whole Pi? In this case, you have to include a relay and switch off\on power to the gateway via GPIO by a running a simple script.
It's VERY easy to do.

actually, MOSFET is more than enough

Thanks guys, worked it out in the end. Set the NRF to low power and the thing stopped going offline.
Cheers for your help.

Hi mattLittle. How did you manage to put the bed low power on rPI? I've the same problems...
Thanks Gianluca
