ccollins476ad opened a new pull request #352: Make BLE sample apps more robust
URL: https://github.com/apache/incubator-mynewt-core/pull/352
 
 
   There are several environments in which the sample BLE apps fail to run:
   
   _bleprph(_oic)_
   * *Low MTU.*  Several devices use a BLE ATT MTU of 104 (e.g., Mac OS).  With this MTU, some newtmgr responses failed to send.  The fix is to increase the number of mbufs and decrease their size
   
   * *Image upgrade.*  Image upgrade requires a fairly large main stack.  The default values for both bleprph apps was too low, resulting a crash during processing of the upload request.
   
   _bletiny_
   
   Bletiny had grown too large to fit on an nRF51.  This PR reduces bletiny's code size in the following ways:
   
   * Remove support for newtmgr-over-shell.  Newtmgr isn't included in bletiny anyway, so this change removes unused functionality.
   
   * Make bletiny help optional via the BLETINY_HELP syscfg setting.
   
   * Make support for the alert notification service ooptional via the BLETINY_ANS syscfg setting.
