Autonomous Read Mode
Overview
Autonomous Read Mode is one of the two foundational read modes in Keonn's readers. It gives full autonomy to the RFID module to read RFID tags using the configured antennas.
Best Practices
Because the reader works asynchronously the services that post data to an external server work specially well:
HTTP Service
SQL Service
MQTT Service
However, if real time acces to the data is imperative the TCP socket 3177 has the flow of all read data plus other stuff from the reader.
This is a diagram on how the read mode works:
Limitations
Because the read mode gives full control to the RFID module to control what antenna to read the full capabilities of the reader offers in terms of number of antennas cannot be exploited. These are the max possible antennas that can be configured on each port per reader:
AdvanReader-m1-70: 8 antennas
AdvanReader-m2-70: 4 antennas
AdvanReader-m2-160: 4 antennas
AdvanReader-m4-160: 4 antennas
AdvanReader-m4-160 Rev 02: 1 antenna
(No longer sold) AdvanReader-m4-150.03: 8 antennas
Users interested in circumventing these limitations should take a look at the other fundamental read mode: SEQUENTIAL
Footnote
Because this is a fondational read mode, the information written here also works for AUTONOMOUS-derived read modes such as Alarm modes.
Summary of differences with SEQUENTIAL
This read mode is start and forget so to get data you subscribe to the reader or use one of the services to send data, SEQUENTIAL by default requires being polled for data.
This read mode has antenna limitations, SEQUENTIAL has no software limits on how many antennas can be used.
In this read mode the RFID module decides which is the best antenna to use in each mode, in SEQUENTIAL fixed antenna time can be unsuitable for tracking moving tags.
