Overall impression with SPIRIT1 ISM radios ?

[gahelton1]

I have been attempting to use Silicon Labs Si443x/RFM22 ISM radio IC for over a week now with no success. My overall impression of this radio IC is poor. Lots of issues, erratas, and twitchy-spazz operation even under ideal conditions. So naturally I am looking for another line.

What about SPIRIT1 ISM radios ? What is your experience ?

Looking for 915MHZ, FSK/2-FSK modulation, 19.2KBPS, simple packet handling with preamble - sync - 5 byte fixed packet length - no crc. And most of all, few hassles, no twitchy spazz operation, no complex software/hardware work-arounds for a poorly designed IC, no wondering WTF, why did it do that ?, that's not in the datasheet.

If you can't get this working in a simple one transmitter, one receiver setup located in Faraday Cage in a couple of hours (tops), then I will keep looking.

Looking forward to your responses.

Hi gahelton,

Both SPIRIT1 and S2-LP can be suitable for the task.

It can be simply configured through SPIRIT1 / S2-LP DK GUI, on top of a STM32 Nucleo board + SPIRIT1 / S2-LP expansion board, like:

I'm sure it will take less than 1 hour to setup the boards to test.

Thank you.

Best Regards,
