RC-WuTRx-XXX

eyJpdCI6Ildha2VVcCByZWNlaXZlciBtb2R1bGUifQ==

Ultra Low Power Wakeup transceiver module

 

Ultra Low Power WakeUp Transceiver allows to optimaze the power consumption for IoT application. It is a transceiver module that uses «wake up receiver tecnique» to be used in very low consumption applications.

The WakeUp-Receiver continuously monitors the wireless channel (without the use of a microcontroller) and recognizes if there are any radio signals addressed to him, in this case it returns the data received on the serial interface. The device wakes up every 1000ms (this time is programmable) for a time of 250µsec. In these conditions the average of the consumption is 10µA with a Sensibility of -110dBm.

The device RC-WuTRx-XXX is based on the CC1310 device from Texas Instruments, and it is available at three frequencies : 433MHz - 868MHz and 915MHz.

Device Resources

DIGITAL SWITCH

It is 4 digital inputs, by default at 1. In the functionality denominated "Wireless Switch",when this input is put at GND, the digital outuput of the corrisponding module will be activated (K1-RL1, K2-RL2, K3-RL3, K4-RL4).

DIGITAL OUTPUT

These are 4 digital outputs, by default at 0. In the functionality called "Wireless Switch" these outputs go to 1 when the Digital Switch of the module corresponding has been activated (K1-RL1, K2-RL2, K3-RL3, K4-RL4). In the function called "Wireless Actuator» these outputs can be driven by the module corresponding by means of simple commands on the serial interface.

DIGITAL INPUT

These are 4 digital inputs, by default at 1. In the function called "Wireless Actuator" the status of these digital inputs can be read by the corresponding module by sending simple commands on serial interface.

SERIAL PORT

The serial port is used to configure the device. In the "Wireless Actuator" functionality to send commands or queries to the remote device. In the "radio modem" functionality to send messages to the device remote.

CTR

In operating mode EU (Low consumption) allows you to enable the sending of commands to the corresponding module.

1- WIRELESS SWITCH FUNCTIONALITY

Using the digital switches K1 ÷ K4 of Device A (B), it will be possible to activate / deactivate the corresponding digital outputs RL1 ÷ RL4 of Device B (A) and vice versa. Each time a command is made, an ACK is sent to the transmitter device. Bidirectionality Active.

 

2- WIRELESS ACTUATOR FUNCTIONALITY

By sending simple commands on the serial interface of Device A (B) it is possible to activate / deactivate the digital outputs RL1 ÷ RL4 of Device B (A) and vice versa. By sending simple commands on the serial interface of Device A (B) it is possible to check the status of the digital inputs S1 ÷ S4 B (A) and vice versa. Each time a command is performed, an ACK is transmitted to the transmitter device on the serial interface "character da". Bidirectionality Active​

 

3- RADIO MODEM FUNCTIONALITY

With this function a Rs232 wireless link is realized, preamble and CRC are automatically generated and added to the RF transmission. The Device configured in EP Mode, immediately transmits the data presented on the serial interface. Bidirectionality Active

2- WIRELESS ACTUATOR FUNCTIONALITY

By sending simple commands on the serial interface of Device A it is possible to activate / deactivate the digital outputs RL1 ÷ RL4 of Device B.

3- RADIO MODEM FUNCTIONALITY

By transmitting data on Device A, they will be present on Device B.

 

Note:

Device B is used as a simple receiver module with very low consumption (10µA) without any bidirectionality. Device A control DEVICE B, if there is a need to

transmit from Device B it is possible to use an external microcontroller (TX enable input), which enables the transmission from time to time.
