Hi everyone,
I’m currently experimenting with a low-power wireless sensor project using the MC33594FTA RF transceiver. The idea is to build a simple point-to-point telemetry link for temperature and voltage monitoring in remote enclosures without needing Wi-Fi or LTE.
So far, I’ve managed to get stable communication at 433 MHz using the demo configuration, with the MCU sleeping between bursts to save power. I’m impressed by how sensitive the receiver is, I’m getting clean data over 80 meters indoors. However, I’m still fine-tuning the SPI interface timing. the MISO line occasionally returns partial data when the transceiver exits standby.
I’m also planning to test pairing multiple nodes on separate IDs using the address filter feature. Has anyone here worked with that setup before? I’m curious how the MC33594 handles packet collisions or overlapping transmissions when multiple transmitters are active.
Any tips on optimizing for low-current operation or best antenna matching practices for this chip would be greatly appreciated. I’ll share some scope traces once I finish the stability tests.
Thanks
