# nRF52 example project
This example shows how to use mongoose on nRF52 boards.
To run it you will need:
- [nRF52 DK](https://www.nordicsemi.com/Products/Getting-started-with-the-nRF52-Development-Kit) dev board
- Linux machine with 6lowpan module enabled. There are a few tutorials out there,
e.g [this one](https://devzone.nordicsemi.com/blogs/972/setting-up-ipv6-over-ble-using-nrf52-series-and-co/)
- [Docker](https://docs.docker.com/engine/installation/linux/)
## Building firmware and cleaning
Nothing special: `make` and `make clean`.
## Flashing
`make flash`
## Watch debug output
This is a two-step process:
- In a separate terminal, invoke `make jlinkexe`. It will run `JLinkExe`
utility, in which you'll need to type `connect`. You can actually do a lot of
things there, including halting and stopping the target, flashing firmware,
etc. You can type `?` to get the list of all available commands.
- Now, in another terminal, invoke `make rtt`. It will start RTT client which
will connect to the running `JLinkExe` and will show logs from the device.
## Debug with GDB
This is a two-step process:
- In a separate terminal, invoke `make gdbserver`. Note that `make jlinkexe`
and `make gdbserver`, unfortunately, cannot run sumultaneously.
- Now, in another terminal, invoke `make gdb`. It will start GDB session which
will connect to the running GDB server.
