Description: Set the work mode for BLE.
X - 0: BLE peripheral mode, 1: BLE central mode. 2: Beacon scan mode.
Y - 0: normal range, 1: BLE long range.
BLE Peripheral Mode
For the Peripheral Mode, you can scan RAK4600’s BLE and connect with it using your mobile device.
BLE Central Mode
For the Central Mode, RAK4600’s BLE will not broadcast so that your mobile devices will not be able to scan it.
This is very useful if you want to make the RAK4600 act as a BLE Gateway wherein BLE Sensor Nodes (up to 20
Devices) can send sensor data.
Beacon Scan Mode
For the Beacon Scan mode, RAK4600 can scan around the Beacon signal, it is useful for Beacon use case like
iBeacon.
RAK4600 BLE Default Settings
By default, the RAK4600 Evaluation Board will work on Peripheral Mode. In this mode users can configure it
through BLE including DFU easily. It should be noted that after resetting the RAK4600, the user has only 60
seconds to establish a connection with your Mobile Device through BLE based on its power consumption settings.
If no connection has been established within 60 seconds, the RAK4600's BLE signal will not be broadcasted and it
will enter power saving mode. On the other hand, there is no limitation once you are already connected with the
RAK4600's BLE.
If you set the RAK4600 to work in Central Mode, the RAK4600 will work first on Peripheral Mode for 30 seconds
and if no connection is established after 30 seconds, it will automatically work in Central Mode. In this mode,the
BLE signal of the RAK4600 will stop broadcasting and will not be visible on your mobile devices up until you
change the work mode to peripheral mode or reset the RAK4600 again.
Burning the Firmware
If you want to get a pre-compiled firmware instead of compiling the source code by yourself, you can find the latest
firmware on RAK website after it is released
.
Flash the firmware using DAPLink and RAKDAP
Please refer to
Upgrading Firmware through DFU using BLE
1. Download the DFU package of the RAK4600 Evaluation Board
and save it on your mobile phone.
2. Make sure the Bluetooth on your mobile is turned on. Open the nRF Connect Mobile application and you will
see all BLE devices in range in the scan list:
