 The software platform is to be based on the Microchip TCP/IP stack on the device. The first edition of the server-side software will be a simple TCP server written for GNU/Linux.
+==== Firmware releases ====
+The firmware code is heavily limited by the fact that it is limited my Microchip's licensing. This means, you may
+only "use, modify, copy and distribute" the Microchip code "when embedded on a Microchip microcontroller [...]".
+My code however, you are free to use under a four-clause BSD license, as long as you filter the Microchip
+code away :P
+Firmware version 1.0 is available!
+  * Want to hack, or add it to your own PIC-MINI-WEB?: {{:projects:tempdude-firmware-1.0.zip}}
+  * A known bug exists: the destination port number is fixed at 13579. Config does work for IP but not port.

+==== LEMP1 ====
+Writeup of the LEMP1 protocol is still a todo. BUT, a software-based reference implementation exists
+as tempsend.c, available here: {{:projects:tempsend.c.txt}}
+Compile tempsend using e.g.
+  gcc tempsend.c -o tempsend
+Command syntax for tempsend is:
+<code>
+  -s <ip of LEMP server>
+  -p <portnumber of LEMP server>
+  -i <node id>
+      Node ID is five bytes, written as hexadecimal digits.
+      Software Node ID _should_ start with 01, and the last
+      byte should be a sensor index. i.e. 01 for a single sensor system.
+      Example of valid Node ID string: 0100FF0201
+  -v <value as float>
+      The value is parsed from string to double, and should be
+      within the range 155.0 to -55.0
+</code>
+To give an example command, let's send -14.5 degrees centigrade to a LEMP1 server
+running at 10.0.3.4 port 13579 (default port) using 0x0102030401 as sensor id:
+  tempsend -s 10.0.3.4 -p 13579 -i 0102030401 -v -14.5
+A node about sensor ID's: ID's are typically locally significant to the LEMP server
+you are reporting to, but the following guideline should be followed:
+  * The sensor ID is to be built up of
+    * one byte manufacturer ID, using 0x01 for software agents.
+    * Three bytes Node ID
+    * One byte sensor index
+  * The first byte should always be 0x01 for software sensors.
+  * The next three bytes should be locally unique for each monitoring station
+  * The last byte should be a sensor index for sensors attached to the monitoring station.
+So, having a monitoring station with five sensors, reporting using software agent, the sensor
+ID's can be something like
+FF0201
+FF0202
+FF0203
+FF0204
+FF0205
+where 00FF02 is the "unique" Node ID.
