An npm package for Node.js that provides an API to control a router node in a BLE mesh network via the serial port.

BLEMeshSerialInterface is defined in 'index.js' and it has public methods for interfacing with the ble mesh device and opening/closing/writing the serial port. It also emits events on specific serial port events and ble mesh events. For now, see /* API Methods / and / nRF Open Mesh Serial Interface */ in 'index.js.' For info about the events BLEMeshSerialInterface emits, search 'index.js' for 'this.emit'
- Only one serial port can be opened per instance of BLEMeshSerialInterface. If you have COM1 opened, and then call openSerialPort(COM2), COM1 will be automatically closed.
- The constructor returns immediately, then to use any commands that send over serial you must explicitly call openSerialPort.
