Hello all.
I wonder if you can help me. I'm using the SimpleSerial code from here:
http://processors.wiki.ti.com/index.php/SimpleBLEPeripheral_SerialInterface
with the 1.4.0 stack and 8.30.3 compiler. All was ok until I tried to change the characteristics to be read/write. It seems that no matter what I try, the characteristics remain in their original state. I'm viewing the device using LightBlue on my iPhone 5s, running ios7. I've tried other apps (BTLExplorer) and the results seem to be the same.
My simpleGATTprofile.c has the following entries:
/*********************************************************************

Does anything else need changing?
Thanks
