Hello everyone,
I’m experiencing an issue with communication between two STM32WL33CC1 devices. I’m using one for LPAWUL wakeup receiver and the other for MRSUBG transmitter, but I noticed that beyond 10 meters, the communication starts failing.
Setup Details:
SB1 resistor: 0Ω
-C3 resistor: 0Ω
-Configured for +20 dBm PA
-Test environment: tested indoors in a hallway
The communication works fine up to 10 meters, but beyond that, wakeup packets are not received reliably.
Can everone help me solve this problem and get +/-30 stable meters?
