BLE CLA example

Note: For an initial understanding of bplib and DTN, it might be helpful to look at the UDP + native example first.

2 devices

Using the BLE L2CAP CLA, each node is either a client or a server. A client connects to the server by a fixed MAC address currently and a server accepts any connection.

To test this, flash it once for the client and once for the server. This can be selected using the ROLE flag. For the client, the remote MAC address to connect to should also be set with the REMOTE flag.

So either make all ROLE=client REMOTE=d8:6b:d5:e9:ca:99 or make all ROLE=server.

When both devices are running, bundles can be exchanged by using the bp shell command.

In this version no storage is used (bplib_stor_void) and bundles that cannot be delivered immediately will be dropped.

This can be changed in the Makefile by selecting a different storage module (bplib_stor_vfs_ordered or bplib_stor_vfs_unordered), a vfs implementation. Refer to the UDPCL example Makefile for more details, of how to set the path under which bundles are saved.
