I am working on WL1873Q (the one with GPS IP) using BBB + TI Processor SDK V03.00.00.04 + AM335x BluetopiaLinux Production V4.0.3.0.1.0
Before adding ti-st driver (to make GPS work), my device tree has tibt node, Bluetopia works ok. In order to make ti-st driver work, tibt node was changed to kim node to accomodate GPS driver, but Bluetopia stops working. Please refer to terminal outputs at the end of this post.
Q1: How to make Bluetopia work with kim node in the device tree? or how to make bluetooth and GPS both work with shared transport driver?
Q2: In the old TI Wiki "TI Bluetooth Stack for WL18xx - Getting started guide" (saved to local pc on 12/14/2016), I read "currently all available serial SDK need the following patch to the serial driver for having flow control working which is needed for bluetooth". A table below this line listed the first patch as "Diable shared transport patch".
Is SDK V03.00.00.04 the one that needs to have its shared transport disabled in the device tree if using bluetopia?
Q3: In the updated TI Wiki "TI Bluetooth Stack for WL18xx - Getting started guide (http://processors.wiki.ti.com/index.php/TI_Bluetooth_Stack_for_WL18xx_-_Getting_Started_Guide),
The requirements on patches are gone. What are the difference between TI Bluetooth 4.2 Stack Add-On for Linux and V4.0V4.0.3.0.1.03.01? Can the former one be used for my application?
