simonratner opened a new issue, #161: URL: https://github.com/apache/mynewt-mcumgr/issues/161
SMP notifications used to deliver SMP responses over BLE transport are corrupted on the [apollo3_evb](https://github.com/apache/mynewt-core/tree/master/hw/bsp/apollo3_evb). Below is a sample log from nRF Connect app attempting an `image list` command (as part of the DFU process). You can see the response being fragmented over two notifications, with the second notification corrupted. As a result, the concatenated CBOR is not decodable. The response does not need to be corrupted - the issue exists even for single-packet responses. This is reproducible with stock [bleprph](https://github.com/apache/mynewt-nimble/tree/master/apps/bleprph) on [apollo3_evb](https://github.com/apache/mynewt-core/tree/master/hw/bsp/apollo3_evb). This is NOT reproducible with the same app on [nordic_pca10056](https://github.com/apache/mynewt-core/tree/master/hw/bsp/nordic_pca10056). Error can be observed with the nRF Connect app or the nRF Device Manager app for Android/iOS (CBOR Error). ``` V 17:20:50.573 Connecting to 66:77:88:23:BB:EF...
