I've bought a S2LP dev board STEVAL-FKI433V2 as I'm evaluating the S2LP for a product revamp.
Because it will be used with a legacy system I want the receive side to completely bypass the packet decoding and output to GPIO - which seems to work to a point.
My issue is that sensitivity is LOW. I don't have a setup to measure it directly, but I have a key fob transmitter outputting about -10dBm. Typically this gives me a working range of 50 feet, but using this eval board I get about 6 INCHES. I'm scoping the data from the GPIO and I can see bits dropping off from the packet after literally a few inches from the antenna.
I'm not sure how much of the packet engine, rx timers, blanking etc is being used? The signal has a very short preamble of 010101, a single sync pulse then about 80 bits of 10kbps data after Manchester encoding so on-chip packet detection doesn't normally work very well.
Can I use the S2LP this way?
