RAK4600. By setting the RAK4600 in the central mode, the RAK4600 acts as a BLE gateway. In the central
mode, "Nordic UART Service" is supported.
3. Beacon scan mode: The RAK4600 will scan the surrounding BLE signal. This mode is useful to scan for
beacons like iBeacon near you.

NOTE:
For the central and beacon scan patterns, you need to use the API development of RUI to play its role. For
BLE related API interfaces, refer to
By default, RAK4600 BLE will work in the peripheral mode so that you can configure it over BLE, including DFU.
Every time after resetting, you have only 60 seconds to connect your mobile device with RAK4600 over BLE. If
you don’t connect with RAK4600 in 60 seconds after resetting it, the RAK4600 BLE radio will not broadcast to
reduce power consumption. There is no limitation once your mobile device has connected with RAK4600 over BLE
in 60 seconds.
Surely, you can set RAK4600 BLE to work in the central mode. After a RAK4600 module reset, there will be 30
seconds that RAK4600 BLE radio works in the peripheral mode. In peripheral mode, you can connect to RAK4600
through BLE using your mobile device and configure RAK4600 over BLE. But if you don’t connect with RAK4600
through BLE in 30 seconds, the RAK4600 BLE radio will change to central mode automatically. In central mode,
RAK4600 can not be scanned by your mobile devices until you change the work mode to the peripheral or reset
RAK4600 again.
Miscellaneous
Upgrading the Firmware
Before you start working with the RAK4600, it is recommended to keep the RAK4600 updated to the latest version
of the firmware. The latest firmware can be found in the software section of the
In the following sections, two (2) options for flashing new firmware in a RAK4600 are shown: Upgrade through
DAPLink and Upgrade through BLE.
