Hi,
We have a WM-Bus receiver in mode Normal design with the CC1125 radio and work fine.
Know the recveiver must be always on in recepcion mode, but the consumption is very high (26mA).
We are trying to configurate the module in sniff mode, to reduce the current consumption.
We follow the AN swra428a and configurate the module registers with the smartRF studio7.
WHen the module is in Normal mode, we received all frame from the meters.
When we configurate the module in sniff Mode don´t receive frames, only a 1-2%.
We calculatethe timers Tevent0 throught the excel CC112x_RX-Sniff_Mode.xlxs, always with the same result:
The meters send a frame ever 11 sec.
We try with the termination CS o PQT.
In Normal Mode we use this registers:

Any idea why don´t wake up from sniff mode?
Thanks in advance
