XCHANGES DESCRIPTION
The exchange protocol used for the LoRaWAN Coordinator Command Line Interpreter (LWCCLI) is built with
ASCII frame made up of 7 bits characters ended with the <EOL> character.
It allows 2 types of simple exchanges:
The “Request/Response”:
HOST

<Request>

LWC
HOST

<Response>

LWC
The “Indications”:
HOST

<Indication>

LWC
The responses can either directly return the required data or constitute a simple acknowledgement to the
request. The requested data may be sent later as an
<Indication>.
Typically, this is the way of working
for frames sent to the end-devices.
A general representation of each 3 possible command lines can be seen here below:
<Request> ::=
<Cmd> <MS><DevRef>[<Param><Op><Val>] <EOL>
<Response> ::=
<ResType><Cmd> <MS><DevRef><MS><status>[<MS><Param>[<Oper><Val>]] <EOL>
<Indic> ::=
<Ind> <MS><DevRef>[<MS><Param>[<Op><Val>]] <EOL>
Each <KeyWord> is defined in the following chapters
N.B.

The KeyWords accept two formats: a short one and a long one (ex:
DEVICE_LIST
<->
DL
). Indeed, a
specific LWC Server parameter allows to choose the wanted format:
VERBOSE
.

All the non-numerical values has to respect the letter case
