1.0.0 rc.1

[paidforby]

Merging 1.0.0-rc.1 branch into master. This introduces a number of backwards compatibility breaking changes so it should not be used in environments with old, not up-to-date nodes.

Changes include,

• fixes Switch from using String to using struct for messages between server and clients #48, stopped using String for communication between firmware clients, now using datagram structs,

struct Datagram {
    uint8_t destination[ADDR_LENGTH];
    uint8_t type;
    uint8_t message[239];
};

• includes contributions from @beegee-tokyo in PR Fix main.ino Welcome Message, BLE client, OLED client and Console. #56

• reduced LoRaLayer2 addresses to 4 bytes as discussed here Using this protocol in similar projects? LoRaLayer2#10

• other updates LoRaLayer2 as of sudomesh/LoRaLayer2@ae51303

• adds banner and prompt to console, removes instances of serial print in console as described in Remove Serial.prints from Console.cpp #65

There are more changes that are coming, including fifo buffers for LoRaLayer2, a user configurable duty cycle option, and possible updates to the web app and maybe even support for two LoRa antennas, so keep an eye out for a 1.0.0-rc.2 branch.
