The DE and RE lines are asserted HIGH only when one or several characters have to be transmitted over the RS485 differential bus: when a radio frame is demodulated, the lines are asserted HIGH and then the data extracted from the radio frame are sent to the module TXD line and therefore to the RS485 differential bus.

RF53 User Guide RSSI reading The RSSI (Received Strength Signal Indicator) gives an indication for the received power level on the first channel of the hopping table. It could be accessed with ATS230?<cr> command. Power level The RSSI level is only an indication. Use this level with care due to the dispersion between components. -
Page 15: Command Mode
RF53 User Guide Command mode The command mode is used to read and update the modem configuration registers using AT command. The AT command can be locked using ATPWD command. In command mode, the radio is inhibited (reception and transmission), excepted when using test command. -
Page 16: Transceiver State Machine
RF53 User Guide Specific string when specified Transceiver mode The transceiver mode used a secured addressed protocol. The communication is always half-duplex. The radio transmission is processed prior to the radio reception. When the transceiver is sending a radio packet, it is not able to decode any incoming radio packet. -

- Page 22 RF53 User Guide without flow control, while using a serial baudrate greater or equal to 9600 bauds will produce data overrun. We recommend to use RTS handshake (S216=0) for serial baudrate greater or equal to the radio rate in order to avoid FIFO buffer overlap. For example with serial baudrate greater or equal to 9600 bauds for Narrow band (radio rate 10 kbits/s) and serial baudrate equal to 57600 bauds for Wide band (radio rate 57600 kbits/s).
