Undefined reference errors while compiling cc1011/firmware.elf

[no1knows]

Can't wait to try this :) I'm seeing the following errors while trying to build the firmware on my Fedora server. Any pointers gratefully received!

[JNSwanson]

Have you got the radio module attached? It is the WDT resetting probably when trying to set up the SPI or radio.

[no1knows]

I do... and have double checked the wiring (photo attached). I haven't tested my CC1101 module, and the build quality doesn't seem great so it could be a dud. I'll do some testing with some basic CC1101 example scripts and see how I get on. Edit: I can now see that my CSN / D8 wire had popped out...

[no1knows]

Seems to be working fine with some simple Arduino example sketches. Definitely no need to connect GDO0 and GDO2?

Edit: Seems to have resolved itself after reconnecting everything - I'm now getting much more promising logs:

[22:09:11]SPI OK
[22:09:11][W][iBoost:111]: SPI OK
[22:09:11]Radio OK
[22:09:11]Radio RX OK
[22:09:11]Setup Finished
[22:09:11][W][iBoost:163]: Setup Finished

Edit 2: So all the entities/sensors are showing as Unknown in HA. This may be due to the frequency issue you mention in the readme, so I'll try a few of the suggestions you included. I don't own a Buddy, but I do know they need to be paired with the iBoost unit - is that not necessary with the NodeMCU+CC1101?

[JNSwanson]

I don’t think a buddy was necessary for the code to work, but it was very useful in decoding the protocol. You don’t need to pair it as it just uses the strongest signal. You should be seeing packets from the sender at least, so I suspect the rx is a little off frequency. The one I tried was out by 75kHz. It will only work with units that support the Buddy ie the iBoost+ and not the original iBoost.

[JNSwanson]

Btw I used sdrsharp to check the frequency offset. You would need to modify the code to force a transmission so you can see the difference

[no1knows]

Thanks for the pointers. I do have an iBoost+ but no Buddy. I may be out of my depth somewhat here - I wonder if there's software-defined radio that's more accurate out of the box. I'll see how I get on with some of your other suggested frequencies.

Could you help me understand how the values in the table translate into the CC1101_FREQ[0-2] values I need to plug in?

[JNSwanson]

The middle of the table vertically is the nominal centre frequency and the entries go up and down by 25kHz. You will need to edit the 3 lines where the frequency is defined and see if you start receiving packets. I would try +/- 50kHz then +/- 100kHz. Given the modules seem to be out of tolerance I might try to automate the process. It may help if you are close to the sender unit.

[no1knows]

Got it! Just realised that the 21656A in the table corresponds to:

radio.writeRegister(CC1101_FREQ2, **0x21**); // 868.300MHz  (868300000 <<16)/26000000
radio.writeRegister(CC1101_FREQ1, **0x65**);
radio.writeRegister(CC1101_FREQ0, **0x6a**);

Will try some others out. An auto solution would also be great :)

I am slightly concerned that without pairing a Buddy the unit won't be transmitting anything, but let's see.

[JNSwanson]

The code emulates what the Buddy does, so I don’t think you will need one.

[JNSwanson]

It doesn’t start transmitting until it has received a packet from the sensor or a Buddy

[JNSwanson]

In any case you should see the received packets in the log.

[no1knows]

Sadly no luck with +/- 50Khz and +/- 100khz - no sign of any packets in the log. Will try again closer to the sender and, in the meantime, may order the Epson xtal!

[JNSwanson]

Maybe try the 25kHz spacing. I noticed from you photo that D8 isn't connected. I assume you have fixed this?

[JNSwanson]

I tried it with the Buddy disconnected and it works ok. You do need to be in range of the sender though.

[no1knows]

Ah, interesting. The sender is a long way away, which I suppose means I need to get the frequency spot on. I just replaced the crystal with the Epson X1E0000210666 from Farnell (2471832), reset the frequency settings in iBoost.h and... hey presto:

[22:08:38]Got packet,27,f2,01,00,0b,08,0b,12,25,2b,20,00,00,00,00,00,00,00,00,00,00,08,0e,0a,09,0b,0d,22,2d,21,05,00,00,00,00,00,00,00,00,00,00,0b,0f,03,,len=44 Signal=-91 LQI=52
[22:08:38]Updated the address to:27,f2
[22:08:39]Sending request

All data is now showing in HA, and the boost/cancel buttons are working too. Awesome! Thanks so much for creating this, and all your help troubleshooting!

[maksyms]

I just wanted to leave this here as well: I experienced the same issue as @no1knows, but I followed the advise to resolder the crystal - and all is working right away! Thank you!

JNSwanson Thank you for all your hard work.

After trying to get it working and wouldn't I managed to resolder the crystal (using a soldering iron, took 3 attempts) but now all working and love having my iboost data in Home Assistant

Thank you - PS have you got a buymeacoffee or something like that?
