EnOcean Click

PID: MIKROE-1908

Weight: 29 g

Status:

EnOcean click carries a TCM 310 transceiver, which is a bidirectional gateway for EnOcean’s 868 MHz radio systems. The click is designed to run on a 3.3V power supply. It communicates with the target MCU through UART (TX, RX pins), with additional functionality provided by RST and EN pins.

Note: Modules with 868 MHz frequency are suitable for Europe and other countries adopting R&TTE specification. Versions of EnOcean click covering different frequency bands will be available in the future.

TCM 310 transceiver

This low-powered wireless module is intended for use together with EnOcean’s range of energy harvesting modules that include self-powered, battery-free wireless switches, sensors and actuators.

Essential features

EnOcean offers a range of modules compatible with TCM 310. Those are miniaturized energy converters that use the surrounding environment — motion, light or temperature differences — to harness enough energy to send a wireless signal to the receiver onboard EnOcean click.

The TCM 310 module can also be set up as a repeater to extend the range of the signal. You can then develop various battery-free switching systems, data loggers and similar.

Onboard antenna

EnOcean click features a small high-performance 868MHz chip antenna onboard so no external antennas are required.

Programming

The function sends ESP3 packet header and data over UART interface to an EnOcean module.

01 uint8_t sendMessage(ESP3Pack* esp){
02 
03   uint8_t i=0;
04 
05   if((esp->header.dataLength || esp->header.oppDataLength) == 0)
06    {
07      return -1;
08     }
09 
10   UART2_Write(esp->syncByte);
11   UART2_Write((esp->header.dataLength & 0xFF00)>>8);
12   UART2_Write((esp->header.dataLength & 0xFF));
13   UART2_Write(esp->header.oppDataLength);
14   UART2_Write(esp->header.packetType);
15   UART2_Write(esp->headerCRC);
16 
17   for(i=0; i < esp->header.dataLength; i++)
18       UART2_Write(esp->dataESP3[i]);
19   for(i=0; i < esp->header.oppDataLength; i++)
20       UART2_Write(esp->optData[i]);
21 
22    UART2_Write(esp->dataCRC);
23 
24    return 0;
