5.6.2 Indication of Wireless Transmitting
®
Buffer empty: the data in the internal 400-byte buffer is written to the wireless chip (automatic sub-packaging),
When AUX=1, the user continuously initiates data less than 400 bytes without overflow,
When AUX=0, the buffer is not empty: the data in the internal 400-byte buffer has not been written to the wireless chip and the
transmission is turned on. At this time, the module may be waiting for the end of the user data to time out, or the wireless
sub-packet transmission is in progress;
[Note]: When AUX=1, it does not mean that all serial port data of the module has been transmitted wirelessly, and the last packet
of data may be being transmitted.
Subpackage transmitting : the last package of data have been
written to the RFIC. When transmission is on, user can continue
to input 400 new bytes. (The buffer is actually empty.)

5.6.3 Configuration Procedure of Module
®
Only happened when power-on resetting or exiting sleep mode
The self-check procedure
happens when the procedure
of power-on reset, instruction
reset and exit mode 3.
