Firmware
The module is pre-loaded with the bootloader, which supports serial bootloading of firmware update. The
module contains RAEMesh application and comply with the RAE System’s RCS protocol. The module also has
built-in RAEMesh Module Command Interface(RMCI).
This documentation is focused on the instruction on RMCI interface.
The RMCI command interface allows customer to easily access to low level mesh functionality without pain to
develop the firmware. The module can be configured to a GTW to hook up to a getaway or just a stand alone
regular full function node or a Sleepy reduce function node.
Make sure to configure the module to right mode before using.
Quick Start
UART
Via the TXD1 and RXD1 pins the command interpreter can be accessed. The RCM can buffer up to 128 bytes of incoming
data in a software FIFO buffer and uses XON/XOFF flow control. See the datasheet of the Atmel ATmega1281 for more
information about the build-in UART.
Connect Pin5 (TXD1) and Pin7 (RXD1) to the customer board. Use the following settings for serial port.
RTR and STD: 19200bps, 8N1.
GTW: 38400bps, 8N1.
Data Packet
RCM will transmit any data in the { }, all data in the {} will be transparently sent out without radio’s interpretation. The
maximum data packet is 50 bytes including {}.
The data in the {} can be any characters including ‘{‘ ‘}’ ’[‘ ’]’ .
The interval between 2 data packets must be >200ms for RTR and GTW.
The interval between 2 data packets must be >1s for STD.
Wakeup
If the radio is set to STD mode, the Wakeup pin Pin19 (PE7) is used to make the radio asleep and wakeup. A constant
high on this pin will let the radio go to the sleep mode and a low level signal on this pin will wake-up the radio.
The Radio sleep mode is the power save mode so the power consumption can be very low. (<40uA)
The Wakeup pin must be held up to 10ms before sending a data packet.
Power
Ground: Pin1, Pin2 and Pin4.
VCC: Pin39, Pin40. 3.0V or 3.3V
Radio consumes less than 100mW in normal RX/TX mode.
Radio consumes 600mW at TX and 100mW at RX for High power module
Heartbeat
Connect Pin12 to a LED for heartbeat indicator.
Reset
RST: Pin3 Active Low.
