Q: FAQ: Locationing on CC2431 - Having Problems? by 543672
When working with the CC2431 and its location engine (using the CC2431ZDK) please have a look at the following documentation, which can be found in the C:\Texas Instruments\ZStack-1.4.3-1.2.1\Documents\CC2430 directory after installing the Z-Stack installer: swrc073d.zip (70MB) - contains ZStack-CC2430-1.4.3-1.2.1.exe (It can be downloaded from www.ti.com/z-stack)
The Z-Stack User's Guide - CC2431DB (F8W-2006-0025).pdf helps you to understand the basics of the platform; e.g. how to chose the correct project depending on your HW and what Logical Device Types you are targeting (CoordinatorEB, RouterBB, ...)
The Z-Stack Location Profile User's Guide (F8W-2006-0008).pdf explains more details about the usage of the locationing and how to setup the correct location profile (REFNODE, BLINDNODE, DONGLE)
The Z-Stack Location Profile (F8W-2006-0002).pdf contains more info regarding the functionality of the location engine.
Important note: Please be aware that the projects have the NV_RESTORE compile option enabled; i.e. that devices store the network specific information as short address, association tables, PAN ID, frequency, etc. As a result they will remember and reuse this information after a restart. In case you want to remove the stored network information you will have to erase the flash of the device before re-programming it. In the SmartRF Flashprogrammer you can easily do this using the "Erase and program" or the "Erase, program and verify" options. Remember though to tick the "Retain IEEE address when reprogramming the chip" option.

Unfortunately some users have experienced connectivity problems regarding the serial/COM port on their docking stations due to the drivers used to connect the ports of the docking station through to the laptop.
So when you have problems connecting your HW via the serial cable you might want to try it once having your laptop undocked; i.e. plugging the cable straight into your laptop.
