Hello, I recently committed fragmentation support for newtmgr. This is more for reliable transports as it does not care about ordered responses. It helps with transports like BLE which have very small MTU.
Basically, a flag was added for this purpose. This would be a backwards incompatible change and hence the latest mynewt.apache.org/newt/newtmgr and apache-mynewt-core should be pulled. The pull requests associated with this change are: https://github.com/apache/incubator-mynewt-core/pull/109 <https://github.com/apache/incubator-mynewt-core/pull/109> and https://github.com/apache/incubator-mynewt-newt/pull/21 <https://github.com/apache/incubator-mynewt-newt/pull/21>. There is no ticket for this. Regards, Vipul Rahane
