Delta / Mbed OS Delta_CLI

This CLI (Command Line Interface) is based mbed-os. Both NNN50 and NQ620 are supported.

Fork of NNN40_CLI by Delta

BLE CLI Document can be downloaded here .

Note that when evaluate using Windows PC as the host, the Serial driver need to be installed in advance. The instruction is explained in the link below

https://developer.mbed.org/handbook/Windows-serial-configuration

Once installed, a device called 'mbed Serial Port (COM#)' should be recognized in Device Manager, as shown below

/media/uploads/tsungta/mbed_serial_port_1.png

Please open the com port at 115200 8n1 as default
