Sack - Send Ack; Txtm - Transmit Timing - IDEETRON LoRaWAN Manual

*APPK[Key]
To request the current key use:
?APPK
The reply will be:
=APPK[Key]
8.8 SACK – Send ACK
The SACK command determines if the ACK bit of the Frame control field is set in messages send
from the mini gateway.
Also the gateway will check if an incoming message from a mote has the same address as set with
the ADDR command. If the address is a match the mini gateway automatically sends an ACK
message.
To change the behaviour use:
#SACK[Value]
Where [Value] is:
The response is:
*ACK Yes/No
To request the current behaviour sent:
?SACK
The response is:
=ACK Yes/No
Note: having a mote requesting an ACK and also a working gateway will result in a collision
between the ACK message coming from the mini gateway and the gateway. Be sure to disable
any gateway in the vicinity of the test to use this function on the mini gateway.
8.9 TXTM – Transmit timing
The transmit timing is only used on messages send in the down direction. That is from mini gateway
to mote. Transmit timing needs to be switched on if you want to communicate with type A motes.
Value Behaviour
00 Don't sent ACK on address match
Don't set ACK bit in frame control field
01 Sent ACK on address match
Set ACK bit in frame control field
