Did anyone try MiRF-v2?

Did it work?

What is the real-world range?

I am tempted by the low cost and low power consumption of nRF24L01. I want to try to pair it with a low cost and low power consumption uC to implement a sensor network. (Well five sensors and one data collector.) I know this is the domain of Zigbee. But I think nRF24L01 may have some advantages.

What do you think?

Thanks.

Hey OldCow (funny SN),

I’m probably not the most independant source but…

Testing outside on a clear day, the MiRF v2 with ceramic antenna was really pretty short range - like 10-15 feet.

Same day, same setup, two MiRF v2s with RPSMA antenna (small guy) was surprisingly far. How far? We should have taken pictures and a GPS unit. I’d say 140ish feet. Down the parking lot, aross the stree, and up a little hill. It was still low power signal though → the signal went away as soon as trees or our building got in the way.

Thanks Sparky! I will try the SMA version and report back.

P.S. I did not want to call myself OldBull or OldGoat. I am actually an OldMan.
