CC113L: Data receiption in manchester code in ook

Raj Kapoor30

Part Number: CC113L
Other Parts Discussed in Thread: CC1200,

I send a data packet from cc1200 evaluation borad and receive that data in ook modulation without manchester codding.

But when i send that data with the same frequency and symbol rate in manchester code and set cc113l in manchester decode enable, I receive no valid packet with cc113l.

Cc113 config is:

Base frequecy:433.99 Mhz

Rx filter BW : 833.33 khz

Xtal frequency:26Mhz

Data rate:12.3 kbaud

In transmiter also configs are:

Symbol rate 12.3 ksps

Bit rate : 6.15kbps

I hope somone help me solve the problem.

The CC113L does Manchester coding on preamble and sync word while CC1200 is only performing Manchester encoding/decoding on the payload (including optional length and address field) and the CRC.

That means that if you want to receive Manchester encoded packets with the CC113L from the CC1200, the CC113L needs to use a 2 bytes sync word, while CC1200 should use 4 bytes:

Example:

CC113L: 0xD391

CC1200: 0xA65A9656

Unfortunately i config rceiver and transmitter with this syncwors but i can not receive with manchester decode enable :(
Isn't any problem with data rate?

I tested the above with smartrf studio and did not have any problems. Please provide me with the RF parameters you are trying to use and I can try to set up a test for you. I need to know frequency, data rate, sync word you want to use etc.

I can get Manchester up and running from CC1200 to CC113L in Studio but am not able to get OOK up and running. Can you please send me the settings you are using for both CC1200 and CC113L (OOK without Manchester) and I can try to add the MAnchester coding to that?

I really appreciate, i received packets in manchester code with a diffrent transmitter when i codded preamble and syncword as well as payload. your answer was very helpful.
I could not find difference between this two ic with user manual documents.
