[W-MBUS] “After different test, it seems that ‘s’ command works only in ‘RX only’ mode (test 3). Is it normal? “ Yes, you must force RX mode before using the ‘s’ command.

Could we set the DTR to 1 using the configuration program or must vie done in hardware? “[W-MBUS] “in order to assess the SNR threshold of my RC1700HP-MBUS device, I’m mixing the signal from the 169 MHz gateway to the Meter with a white gaussian noise signal. In order to compute the actual received noise power, I should know the amplitude of any filter present in the receiving stage. According to the standard, channels 1a/b, 2a/b and 3a/b have a width of 12.5 kHz and therefore I’m simply supposing that a filter with a bandwidth approx. equal to 12.5 kHz will be present somewhere at the receiver. Could you please confirm my assumption? “[W-MBUS] Which module should I use for Russia?
