CC1352 and LoRa compatibility #25

Closed reiniercoetzer closed 2 years ago

reiniercoetzer commented 2 years ago

Hi Electronic Cats (@Liars126) !

I recently came across your CatSniffer, which is a pretty handy device!

I am currently doing some research on LoRa compatible MCUs and officially it seems as though TI does not support LoRa. However, I also read that the CC1352 (which you guys are using) supports Amazon Sidewalk, which is based on LoRa (perhaps only the protocol?).

For the CatSniffer, I assume you use the Semtech SX1262 for LoRa, but since you are also familiar with the CC1352, do you perhaps know if this MCU is somehow compatible with the LoRa PHY?

Thanks in advance!

Best regards, Reinier

Hello @reiniercoetzer!

Thank you for the interest in our products and your feedback, is much appreciated!

Yes, we use Semtech SX1262 for LoRa and unfortunately CC1352 is not compatible with LoRa.

Thank you for you patience. Feel free to get back to us if you have any further queries.

Kind regards, Electronic Cats Support Team

Many thanks for your feedback!

Maybe useful for someone else in the future (you guys know this of course):

I also got some information directly from TI and as expected the CC1352 PHY is not compatible with the standard LoRa modulation, i.e. LoRa uses chirp spread spectrum (CSS) technology, whereas the CC1352 PHY can do spread spectrum using GFSK, which is more applicable to Amazon Sidewalk for which the CC1352 is supported.
