💬 Building a Orange Pi Gateway

[awilner]

@pansen , Thank you so much!!! I managed to find two pins that didn't give me this error, PA11 and PA12, and now at least the chip configuration and communication apparently works.

[8667]

I wanted to build MQTT client gateway with whitelisting and encryption + 3 LEDs with Arduino UNO and Ethernet shield but it does not have enough memory.

Before going to Arduino MEGA I found this and I think this will be a better way to do it. Smaller, cheaper..just not sure if it has all the options. Can someone confirm? Whitelisting will be easier then reflashing Arduino all the time too.

I plan to use Orange Pi Zero H2+ Quad Core 256MB

[pansen]

If your conditions are

• 3 LEDs: yes through GPIO
• Ethernet: yes (d'uh)
• beefy enough for software encryption: I guess? For an IoT-low data rate scenario for sure

I'm running armbian on my Orange Pi and setting up mosquitto is a breeze. But you don't need a broker right? Don't forget you need an SD card on top and more power.

[8667]

Thanks, I already have a broker and OpenHAB. Want this gateway to act as a client....maybe it will even support SSL MQTT. And encryption with

#define MY_RF24_ENABLE_ENCRYPTION is wanted.

In the article, there is no list of all available configurations...yea adding SD card does not make it cheaper

[pansen]

i'm sorry, i do not have experience with encryption. essentially it depends on the code you want to write, since on the pi you are kind of limited to scripting, whereas microcontroller code is closer to hardware. also, if you need things like an adc or spi you're better of with a microcontroller. if it's just about some LEDs lighting up..

From the article:

For a complete list of configuration parameters, run:

./configure --help

Did you miss this or is there something I'm not understanding?

mysgw: Could not open /sys/class/gpio/gpio10/direction
Please help me to solve this error

[mfalkvidd]

@BAsavaraj004 could you describe what you did when you got that error?

[BAsavaraj004]

@mfalkvidd
When I executed sudo ./bin/mysgw -d this command after that i'm facing error like :

mysgw: Starting gateway...
mysgw: Protocol version - 2.2.0-beta
mysgw: MCO:BGN:INIT GW,CP=RNNG----,VER=2.2.0-beta
mysgw: TSF:LRT:OK
mysgw: TSM:INIT
mysgw: TSF:WUR:MS=0
mysgw: Could not open /sys/class/gpio/gpio24/direction
I followed all the steps provide in the site but still I am getting error.

[mfalkvidd]

@BAsavaraj004 thanks. Earlier posts indicate that the "Could not open" error could be caused by a problem with the pin mapping. I don't have an OrangePi myself so I don't know the details but maybe these posts can help:

Hi,
Well done finally i used the dedicated .fex file for Orange Pi Plus 2E here :
https://linux-sunxi.org/Xunlong_Orange_Pi_Plus_2E#Expansion_Port

at this point :
https://github.com/igorpecovnik/lib/blob/master/config/fex/orangepiplus2e.fex

Read the .fex file in a text editor, u'll see important things about "gpio_config" for H3 cpu :

; NOTE: This section is necessary only for "gpio_sunxi" driver
; which is obsolete for H3 boards
[gpio_para]
gpio_used = 0
gpio_num = 0

I connected my NRF24L01 on OPI P2E like this :

NRF24L01 Port Name / (Pin N°) ----- OPI Port (Pin N°) / Name
                      GND (1)  <-----------> (20) / GND
                      VCC (2)  <-----------> (17) / 3.3V PWR
                      CE (3)   <-----------> (22) / (PA2 / GPIO2)
                      CSN (4)  <-----------> (24) / (PC3 / GPIO67)
                      SCK (5)  <-----------> (23)
                      MOSI (6) <-----------> (19) MOSI
                      MISO (7) <-----------> (21) MISO
                      IRQ (8)  <-----------> NC

So "MySensors" setup is :

./configure --spi-spidev-device=/dev/spidev0.0 --my-transport=nrf24 --my-rf24-ce-pin=2 --my-rf24-cs-pin=67

Then

./bin/mysgw -d

Return :

root@orangepiplus2e:~/MySensors# ./bin/mysgw -d
mysgw: Starting gateway...
mysgw: Protocol version - 2.2.0-beta
mysgw: MCO:BGN:INIT GW,CP=RNNG---,VER=2.2.0-beta
mysgw: TSM:INIT
mysgw: TSF:WUR:MS=0
mysgw: TSM:INIT:TSP OK
mysgw: TSM:INIT:GW MODE
mysgw: TSM:READY:ID=0,PAR=0,DIS=0
mysgw: MCO:REG:NOT NEEDED
mysgw: Listening for connections on 0.0.0.0:5003
mysgw: MCO:BGN:STP
mysgw: MCO:BGN:INIT OK,TSP=1

Best.
Seb.

This worked great on my Orange Pi Lite.
I was trying to follow the tutorial at Building a Orange Pi Gateway and I tried all sorts of things that didn't work.
IMO the main tutorial should have this as instruction to building a gateway with Orange Pi Lite/Plus.
Thanks!!
( Sorry for quoting the entire original post, but this will help anyone searching for help with their Orange Pi Lite)

[8667]

I got the OrangeZero and was building the configuration command... can someone provide me more detailed instructions about using higher security?

1. Is it possible to use SSL for the connecting to the broker?
2. How whitelisting works with Pi? I moved away of Arduino as I do not want to recompile it everytime I need to include new node. So far I have

-my-signing-request-signatures --my-signing-debug --my-signing=password --my-signing-password=SOMETHING --my-rf24-encryption-enabled

but this will not allow me to exclude stolen nodes right?

[Anticimex]

@8667 no, it won't. As it is for the moment, whitelisting works no different compared to Arduino based devices. You will have to recompile your GW if you add new nodes as you will need to add their serials to the whitelist in the GW.

So how personalization works on the orange and how to pass the list of serials?

[Anticimex]

@8667 not sure. I have not been involved in the rPi port. I suggest you pass --help to the configure command. It should give a list of options.

@8667 if there is no option for the whitelist, you should still be able to set it using the same #define as mentioned in the signing documentation. The implementation is shared.
It makes sense to keep it like that since the list could be quite long.

[mfalkvidd]

@8667 a first try of making the help text available online is now available at https://ci.mysensors.org/job/MySensors/job/MySensors/job/PR-952/12/Doxygen_HTML/group__RaspberryPiGateway.html
If/when the pull request is accepted, a link can be added on the build page.

Hello! I followed instructions by SdeWeb on my Orange Pi Lite with Armbian, and gateway is working fine, I can see debug messages from other node. But when I try to add a serial port in node-red I can't find the gateway one. Can you help me?
