CC1101 transceiver from pollin and connections

daniele · October 2, 2016, 5:17pm

Hi all,

I just registered and this is my first message! Thanks for what you are doing in this area.

I have to learn a lot and I bought a set of three MAX! devices and the adapter from pollin listed on the wiki (on the page homegear.eu/index.php/Hardw … quirements , in the section about MAX! devices), as well as a banana pi, so I should be all set

From what I have seen on the wiki, there is a connection-scheme which refers to another adapter (the one from aliexpress, I guess). I would like to know whether there is something similare related to the adapter I bought.

Kind regards,
Daniele

Hey Daniele,

here is what you need to connect:

Modul       RPI
VCC         3.3V
GND         GND
MISO        MISO
MOSI        MOSI
SCK         SCK
CS          CE0
GDO0        GPIO25 (or any other free GPIO)

Then add the following to your physicalinterfaces.conf:

[MAX]
deviceType = cc1100
device = /dev/spidev0.0
responseDelay = 45
# "0" if GDO0 is connected to GPIO of Rasberry Pi or "2" if GDO2 is connected
# You only need one GDO (0 or 2), it doesn't matter which one you use.
interruptPin = 0
# GPIO pin on Raspberry Pi the GDO of the module is connected to.
gpio1 = 25

Cheers,

Sathya

Hi sathya! Thanks a lot for your help.

Now I’m on vacation and I can work on my project!

I did read the thread you posted, but unfortunately my situation is a bit different: On the SBC side I have a Banana PI instead of a Raspberry PI, and on the module side I have a different module (at least the pinout is different).

I am attaching the schematics I reconstructed using your post as input, the datasheet of the module [1] and the description of the banana PI [2].

Can you please let me know if you see major faults with my schema? I don’t want to “fry” anything

Best Regards,
Daniele

Thanks Sathya, off to the soldering station, then!

I’ll keep you posted!

Update: the adapter is connected and it seems to be recognized by the system:

But I had to manually load the module before. I am now installing homegear

Edit: it seems to work: I have seen the following in the log:

12/27/14 16:49:43.319 MAX packet received (cc1100, RSSI: 0x54): 8BC5D44148212[lots of other hex digits that I omit because I fear they may contain sensitive information]

My problem now is that payring does not work and I don’t know why. But I’ll create a thread in the right board.

Thanks!

Ok, I’ll keep posting in this thread because I am not sure wether I have an hardware problem or not.

After connecting the transceiver and installing homegear I’ve seen some packets in the log and was very happy, but from what I’ve seen the pairing packets should not start with 8X (I’ve seen 84,85, 8D).

If I choose a higher debug level I see a lot of CRC errors (many of them each second) and when I try to pair the valves I see a message about a MAX! packet longer than 200 bytes.

@sathya is there a way to test the behavior of the transceiver excluding issues with the antenna? Something like testing the module. Homegear sees two devices (I think one is a “central” since I can issue commands like pon and poff, while the other one can send packets). I’m kind of lost and would like to know if it’s better to test the physical connections or try a different OS.

Thanks!
Daniele

sathya · October 2, 2016, 5:17pm

Hey Daniele,

first, post me the settings in your physicalinterfaces.conf to see if everything is allright there. If it is, the SPI communication can be debugged by enabling debuglevel 6 in main.conf.

daniele · October 2, 2016, 5:17pm

Hello again,

preamble: I have to issue the command

in order for the device /dev/spidev0.0 and /dev/spidev0.1 to appear.

Physicalinterface.conf reads:

[MAX]
deviceType = cc1100
device = /dev/spidev0.0
responseDelay = 45
# "0" if GDO0 is connected to GPIO of Rasberry Pi or "2" if GDO2 is connected
# You only need one GDO (0 or 2), it doesn't matter which one you use.
interruptPin = 0
# GPIO pin on Raspberry Pi the GDO of the module is connected to.
gpio1 = 1

At this point if I start homegear I get the following output:

I don’t see any traffic in the log, even at debuglevel 10. But homegear.err is empty and in the homegear.log file I see:

But, as sayed before: I can’t see anything in the log even at debuglevel10.

At this point if I issue the command

#homegear -s root root

I start seeing packets in the log!

At debug level 4 I see nothing until I initialize pairing from the valve, at this point I see:

There’s your problem. The missing edge file means, the GPIO is not connected to the interrupt controller. That’s why it’s not working.

First try to export all your GPIOs and see if there is one already having the “edge” file. If there is, connect GDO0 to that GPIO and everything should work.
If not, you need another GPIO driver. See if there are other GPIO drivers available by searching for module files containing “gpio”: “find / -iname gpio.ko”. Unexport all GPIOs, unload the currently used GPIO driver and load the found one (gpio_sunxi.ko for example seems to be a working driver for the A10, see link below). Then again, export all GPIOs and see if there is one having the file “edge”. If there is not, you need to google for something like “banana pi gpio interrupt controller”.

Maybe this post helps, too: http://www.cubieforums.com/index.php/topic,253.30.html

Allright, I changed distro to raspbian (for bananapi) which has the gpio utility. I have a different error now. But first some background info:

I perform the following command using the number which is in the “Phys column”:

# gpio exports
GPIO Pins exported:
  12: out  0  none 
# ls /sys/class/gpio/gpio12
active_low  device  direction  edge  power  pull  subsystem  uevent  value

The edge file is there, and I modified the phyisicalinterfaces.conf acoordingly:

[MAX]
deviceType = cc1100
device = /dev/spidev0.0
responseDelay = 45
# "0" if GDO0 is connected to GPIO of Rasberry Pi or "2" if GDO2 is connected
# You only need one GDO (0 or 2), it doesn't matter which one you use.
interruptPin = 0
# GPIO pin on Raspberry Pi the GDO of the module is connected to.
gpio1 = 12

And now when starting homegear I get the following in the homegear.err file:

Thanks a lot for your help, I am truly a noob wrt gpio etc. But I’m learning a lot!

Hey Daniele,

now the SPI communication is not working. Does the device “/dev/spidev0.0” exist? What SPI driver is being used? The default Raspbian driver (spi_bcm2708) does not work with the A20.

Regards,

Sathya

daniele · October 2, 2016, 5:17pm

Hi sathya,

the module is spi_sun7i.ko.
There are two spi-related files in /dev: /dev/spidev0.0 and /dev/spidev0.1

Could it be that the GPIO pin is not the right one? I am not sure whether I should use the physical pin number to export the GPIO (I did so).

Thanks and regards,
Daniele

[quote]the module is spi_sun7i.ko.

ok, looks good.

No, now it’s not a GPIO problem as long as you didn’t connect GDO0 to the SPI pins. Does “gpio readall” still output “Low” for “CE0” and “CE1”?? That’s wrong. Both need to be “High”. Maybe try googling “banana pi raspbian spi howto” to see, if there is something else that needs to be done.

daniele · October 2, 2016, 5:17pm

I’m going back to bananian (which uses a more recent kernel) since now I know how to manipulate the GPIO pins without the gpio binary. With it the SPI seemed to work (at least I’ve seen some packets).

Thanks a lot.

daniele · October 2, 2016, 5:17pm

AAAAND it works with bananian!!! I paired succesfully with the first thermostatic valve!

sathya · October 2, 2016, 5:17pm

Great . How did you get it to work?

daniele · October 2, 2016, 5:17pm

Hello again and sorry for the delay in replying. I’m wrapping up everything I did to make homegear work on the bananapi (bananian distro v14.11).

The wiring that I posted earlier in this thread is working, I did no modification to it. There is one issue, though, the PINS identified as GPIO 0, GPIO 1, etc. are not really GPIO 0, GPIO 1, etc. So you cannot simply “export” these IDs and expect things to work. Since bananian does not provide the gpio binary to find out the mapping, I installed raspbian (for the banana pi) and got the mapping you can find in this thread.
If you use the wiring depicted in my previous post, you have to export GPIO 18, since I used the physical pin 12.

Since bananian 14.11 is debian wheezy (don’t ask me why they used a naming a-la ubuntu, I have no idea) I added the debian repository of homegear. Be aware that you need to install perl (which provides rename) and patch (which provides… patch ), otherwise homegear installation will fail.
Further, bananian is exposing the spi devices in /dev/ with access only for user root, and this means that you have either to change the configuration of homegear in order to make it start, or adapt the OS. I chose the latter approach and did the following:

!!! please don't run random commands you see on the internet on your systems unless you understand them. !!!
# addgroup --system spi #this group will get read and write access to the SPI devices
# adduser homegear spi #we want the user homegear to be part of the spi group we just crerated
# cat > /etc/udev/rules.d/spi-sun7i.rules << EOF
KERNEL=="spi-sun7i*", SUBSYSTEM=="spidev", GROUP="spi", MODE="0660"
EOF
#change the udev rules and give to group spi rw access to the spi devices
# add a row to /etc/modules with the following content, so that the spi module gets loaded at boot time 
spi-sun7i

Now edit the physicalinterfaces.conf according to your needs, be sure to use pin 18 (see my posts with the configuration for MAX! devices) if you used my wiring diagram. Homegear should start without troubles, and should be automatically started after boot.

HTH!
Daniele

Hi!

Thanks for providing the details on getting the CC110x running on the Banana Pi with Homegear.
You should really link this thread to the corresponding Homegear wiki page.

I would also like to report success:

Using an ELV TRX868-TFK module (the small long one) directly connected to the Banana Pi running Bananian.
Used the Debian APT repo from Homegear. I just did a “apt-get install homegear” and after modifying the physicalinterfaces.conf it worked immediately.
together with OpenHAB 1.6.2 and Oracle Java 8

Great!

Hi, i’ve also a Problem with this Pollin Device.

But for my surprise only on the B and B+ RaspberryPi Models.
On a Pi2 it works perfect.

On a B and B+ Model the log says something like this

My config

Any suggestions?
