| Seppo Takalo |
0:bde1843b9885 | 2 | |
| Seppo Takalo |
0:bde1843b9885 | 3 | This application is the simplest one to utilize our mesh networking stack. It just joins your device to the unsecure *6LoWPAN-ND* network. |

0:bde1843b9885 | 35 | |
| Seppo Takalo |
0:bde1843b9885 | 36 | You can read the instructions on updating the firmware of your K64F working as 6LoWPAN border router [here](https://github.com/ARMmbed/mbed-os-example-client#mbed-gateway). |
| Seppo Takalo |
0:bde1843b9885 | 37 | |
| Seppo Takalo |
0:bde1843b9885 | 38 | Please do not forget to connect the Ethernet cable between the border router and your home/office router. Then power up the board. |

0:bde1843b9885 | 52 | ### Changing the radio driver (optional) |
| Seppo Takalo |
0:bde1843b9885 | 53 | |
| Seppo Takalo |
0:bde1843b9885 | 54 | To run a 6LoWPAN-ND network, you need a working RF driver for Nanostack. This example uses the Atmel AT86RF233 by default. |
| Seppo Takalo |
0:bde1843b9885 | 55 | |
| Seppo Takalo |
0:bde1843b9885 | 56 | To change the RF driver: |
| Seppo Takalo |
0:bde1843b9885 | 57 | |
| Seppo Takalo |
0:bde1843b9885 | 58 | 1. Uninstall the Atmel RF driver. |
| Seppo Takalo |
0:bde1843b9885 | 59 | |
| Seppo Takalo |
0:bde1843b9885 | 60 | mbed remove atmel-rf-driver |
| Seppo Takalo |
0:bde1843b9885 | 61 | |
| Seppo Takalo |
0:bde1843b9885 | 62 | 2. Install the new driver. (For example, for the FRDM-CR20A radio shield based on the MCR20A device.) |
| Seppo Takalo |
0:bde1843b9885 | 63 | |
| Seppo Takalo |
0:bde1843b9885 | 64 | mbed add mcr20a-rf-driver |
| Seppo Takalo |
0:bde1843b9885 | 65 | |
| Seppo Takalo |
0:bde1843b9885 | 66 | 3. Recompile your application. |
| Seppo Takalo |
0:bde1843b9885 | 67 | |
| Seppo Takalo |
0:bde1843b9885 | 68 | mbed compile -m K64F -t GCC_ARM |
