💬 Building a Raspberry Pi Gateway

[marceloaqno]

Support for RFM69 was added to the development branch (finally!).

[jirm]

@marceloaqno

I´m really happy ear that !

RFM69 is one of best RF transceivers in these days for IoT.
So good news I believe for Mysensors community.

You know if are any hope that RFM69 will be added too to OPI boards support mysgw development ?

Congratulations for that great work !

[marceloaqno]

@jirm Support for RFM69 also applies to the OrangePi :wink:

[jirm]

@marceloaqno

Awesome !!!
Thank you so much.

Best regards

When I configure "MY_RFM69_MAX_POWER_LEVEL_DBM" in MyConfig.h, compiling fails.
Perhaps you should change the code in ./drivers/RFM69/new/RFM69_new.h from:

#define RFM69_MAX_POWER_LEVEL_DBM MY_RFM69_MAX_POWER_LEVEL_DBM //!< MY_RFM69_MAX_POWER_LEVEL_DBM

to:

#define RFM69_MAX_POWER_LEVEL_DBM ((rfm69_powerlevel_t)MY_RFM69_MAX_POWER_LEVEL_DBM) //!< MY_RFM69_MAX_POWER_LEVEL_DBM

I cannot get the RFM69(HW) working. When I start myswg in debug mode (-d), I see:

mysgw: Starting gateway...

But I can see ('hear' with a radio on 868.000 MHz) no transmission of the RFM69. When I power up a node, the node does not connect to the gateway: "NO REPLY":+1:

Is there any 'check' I can do to perform basic RFM69HW testing on my RPI?

[gohan]

Was it working before on a normal Arduino gateway? How did you wire everything up?

[ftw64]

I'm pretty sure I wired up the RFM69 correctly.
However, I'm debugging. It seems we are stuck in "core/MyGatewayTransport.cpp":

inline void gatewayTransportProcess(void)
{

  if (gatewayTransportAvailable()) {
    // NEVER REACHED

I never seem to get pass gatewayTransportAvailable. I will continue debugging.
Disclaimer: I'm relatively new to MySensors and not really 'up to speed' with the source code :-).

[ftw64]

@ftw64 Ok, this has to do with connecting an Ethernet client. When a client connects, this code works...
Any idea where to start debugging for incoming RFM69 messages?

[gohan]

Download myscontroller and connect it to the gateway, you can now see all messages from ethernet controller

[ftw64]

@gohan said in 💬 Building a Raspberry Pi Gateway:

myscontroller

I just did. When I also have a Domoticz controller connected to the gateway:

However, I found out that the DI00 (=IRQ) on the RFM69 never gives a rising edge...
I'm suspecting that the RFM69 is not being initialised properly... I added some debugging in the RFM69 code to see what registers are being written and read:

Can't get the RFM69HW to work on RPI. I tried the following:

1. I installed on an old RPI1 (clean Rasbian install). Same results as on my Domoticz RPI-3.
2. Setup the original RPI3 as a node, using the 2.2.0-beta code. I verified that in this case the RFM69HW actually transmits (I can hear it burst on 868.000 MHz). However, it is unable to connect to an existing Arduino 2.1.1 gateway.
3. I built an Arduino 2.2.0-beta serial gateway. Even then, the RPI as a node fails to connect to the 2.2.0-beta serial gateway.
4. I built an Arduino 2.2.0-beta node. This node is able to connect to the above gateway.

There seems to be something different in the radio network between the RFM69HW on the RPI and the RFM69HW on the Arduino. But I'm unable to find out what the difference is :-(.

The RPI RFM69HW will not communicate with the Arduino RFM69HW. When the RPI is a gateway, the RFM69HW will not physically interrupt when another node is trying to connect. When the RPI is a node, the RFM69HW on the ARduino does not interrupt either.

Did anyone get the RFM69HW working on the RPI? I'd really like to get this beautiful piece of code working!

[gohan]

I have to ask a stupid question : did you use a logic converter between rpi and rfm69 radio?

[ftw64]

@gohan There are no stupid questions, right :-)? But perhaps a stupid answer: no, I did not use any logic convertors. The RFM69 is 3.3V and as far as I know, so are the GPIO pins on the RPI. But I might be mistaken, of course... Should I use logic convertors?

At the moment I have no idea where it fails. Perhaps I need to give it a rest for a couple of days to think it over...

I followed the steps as given on the web site (git branch development). Connected the RFM radio (7 wires: Vcc, GND, MOSI, MISO, SCK, NSS, DI00). Only modified MyConfig.h with regard to the NETWORKID (100 --> 101; my 'production' MySensors runs at 100) and enabling "MY_DEBUG_VERBOSE_RFM69". I configured with:

% ./configure --my-debug=enable --my-config-file=/usr/local/etc/mysensors.dat --my-gateway=ethernet --my-transport=rfm69 --my-rfm69-frequency=868 --my-is-rfm69hw
% make -j 4
% sudo bin/mysgw -d

The gpio pins on raspberry pi are 3.3V. https://raspberrypi.stackexchange.com/questions/3209/what-are-the-min-max-voltage-current-values-the-gpio-pins-can-handle

[mfalkvidd]

@ftw64 that configure command looks like an ethernet gateway. Could you post the configure command for your "RPI as a node" as well?

[marceloaqno]

I forgot to mention in the guide:
To communicate with the RPi using the RFM69 radio, all of your nodes need to use the new RFM69 driver available in the development branch.
To make the change, add the following line to the node sketch:

#define MY_RFM69_NEW_DRIVER

[gohan]

@marceloaqno you forgot just a little little insignificant detail 😂

[marceloaqno]

@gohan @ftw64 sorry for all the trouble

[gohan]

It's OK, don't worry. We need to update the guide with the new instructions 😀
