PAN1321
The uart/panasonic_pan1321 directory in sigrok-dumps contains a set of example captures of the communication with a Panasonic PAN1321.
The logic analyzer used was a ChronoVu LA8 (at 500kHz):

Protocol
The device can be controlled via a UART connection (RX/TX and also RTS#/CTS# for flow control).
The default baud rate is 115200, but the chip can be reconfigured to other baud rates, too.
The protocol is mostly ASCII-based, using a specific AT command set, publically documented by the vendor.
Commands and responses always end with \r\n.
