Symbol Value Description / Note
t
RX-TXD
600 us Time from last byte is received from the air until first character is
sent on the UART
t
TXD
Min 621 us t
TXD
= # bytes received x 621 us/char (10 bits at 19.2 kBd + 100 us
delay per character)
t
TXD-IDLE
1.5 ms Time from last character is sent on the UART until module is in
IDLE mode (ready for RXD and RX)
t
PACKET-
TIMEOUT
Programmable If enabled, the packet timeout can be configured from 16/32 ms to
4.08 s. If end character or fixed packet length is used, the timeout
is 0.
T
RXD-CTS
14-36 us Time from last character is received by the UART (including any
timeout) until CTS is activated
t
RXD-TX
680 us (1 char)
2.16 ms (16 chars)
Time from last character is received by the UART (including any
timeout) until the module sends the first byte on the air. Depends
on the number of characters to be sent.
T
TX-IDLE
1.4 ms Time from last character is sent on the air until module is in IDLE
mode (ready for RXD and RX)
t
OFF-IDLE
Typ 1.6 sec Long start-up due to slow 32kHz oscillator
t
RESET-IDLE
Typ 28 ms From RESET when 32 kHz oscillator is running
t
SLEEP-IDLE
4 ms
t
CONFIG->
2 ms From CONFIG is asserted until prompt ‘>’ (including the prompt)
t
C-CONFIG
1.6 ms After setting new channel until prompt ‘>’ (including the prompt)
t
CONFIG-M
1.0 ms After sending the ‘M’ command until prompt ‘>’ (including the
prompt)
t
MEMORY-
CONFIG
26 ms In this period the internal flash is programmed. Do not reset, turn
the module off, or allow any power supply dips in this period as it
may cause permanent error in the Flash configuration memory.
After 0xFF the host should wait for the ‘>’ prompt before any
further action is done to ensure correct re-configuration.

CONFIG-IDLE
