Rx/Tx fragment won't let you specify a Frame length Less than 14 bytes

Hi I am trying to sniff the Simplisafe 2 protocol which uses 12 byte frames but the Rx/TX fragment won't let you set a frame length less than 14 bytes.
This shall not be a problem, the RX frame length is only used internally for PandwaRF to know at which rate send the data to phone.
You can set a higher RX frame length.
The frame length counts in bytes as soon as a first byte is detected, so if a wakeup bit or a header is sent some time before the real data, if you set a 14 bytes frame length you will miss the interresting payload.
Also in your image, the RF amplifiers are may be in the wrong state. Click on the 3 dots in the upper right of the app to set the RF amplifiers
You don't understand it won't let me send a length lower than 14. I need it to be 12 and the pandwaRF can't receive Simplisafe 2 packets with the RF amplifiers on OR off..... I have spent the past two months trying to get the PandwaRF to pick up a Simplisafe 2 PIN....
ok, so let me understand: the data you want to capture and which is sent over the air is only 12 bytes @ 2000bits/s, so it lasts 12*8/2000=48ms, right? No data/header before, no data after, only 12 bytes ?
If you do not receive enough data to complete the minimum 14 bytes required, you can always increase the sampling rate in the RX page. You will receive more data (oversampled).
