The query results
Description
Note：The Instruction; should not normally be initiated until the three tuple, Channel,
Working Mode and slot cycle’s (Class B required) setting are complete
Note: the return value after access the network:
Divided into 3 times: OK/ERROR、FAIL/SUCC、TRANS;
OK/ERROR is returned immediately after the Instruction, indicating whether the
module accepts the instruction to start the network;
FAIL/SUCC returns for successful or failed access. Generally returned after 6
seconds.
As for TRANS is unique in Class B mode (Class A and C do not receive TRANS
responses)
Represents that has entered Class B working mode; the return time is generally within
1 ~ 128 seconds, uncertain. The Note Class B startup failed if all 130 seconds were
not returned.
Note: the return value about the query:
NONE、JOINING、FAIL、SUCC、WAITBEACON、TRANS.The following meaning
is given to this article:
NONE: did not start the network access action;
JOINING: is entering access;
FAIL: network access failed;
SUCC: has been connected successfully;
WAITBEACON:in Class B, waiting for the first beacon package (not in class B
working mode)
TRANS: in Class B, already in Class B working mode.
Note: Retry of the network access failure:
An attempt to access instructions again shall be made in 1 second after receiving the
FAIL. When reentering the network, there is no need to set the front AT instruction
(saved to the module) to directly send the network instruction .
Note: About Automatic access to the network:
If there is no AT instruction input within 2 seconds after the module is powered up,
automatically start the access action using the saved configuration (if not set and not
