7 / 16 page EZRadio-2WayLink-DK Rev. 0.1 7 2.2.4. Output Power The current version of the range test demo does not support changing the output power. The output power is defined for +11 dB for all the frequency bands. 2.2.5. Packet Length The user can define the length of the communication packets. The packet length contains 4 bytes of preamble, 2 bytes of synch word, at least 7 bytes long payload, and 2 bytes of CRC. Increasing the packet length increases the length of the used payload. The length of the whole packet can be selected from 15 bytes to 72 bytes. 2.2.6. Maximum Number of Sent/received Packets The user can define the maximum number of sent and received packets. The demo stops after the defined number of packets received or sent. The following packet counts can be selected: 200, 500, 1000, 2000, 5000, 10000. 2.2.7. Node Addresses Each node of the range test demo reads the serial number of the connected RFpico board. The least significant byte of its serial number (0 - 255) is used as node address. The user has to define the address of the destination node in the menu system to pair the appropriate nodes. 2.2.8. Custom Parameters As described earlier, the user can store custom RF parameters into the devices with WDS. One custom field is available in each of the nodes. If custom parameter mode is selected, the RF parameters (frequency, modulation, data rate) are defined by the stored custom parameters and they cannot be changed. Note: Since custom parameters belong to a defined frequency band, the firmware goes to error state if the frequency band of the custom parameters mismatches with the frequency band of the device. 2.3. Error states In case of critical error, the demo goes to error state. Power-on-reset can force the demo out of error state. In error state, LED4 is continuously ON and an error message is shown on the LCD screen. Critical errors: 1. Error message: No RFpico board found! Connect an EZRadio RFpico then Reset! Cause: There is no supported RFpico connected to the LCD base board. Solution: Connect a supported EZRadio RFpico board (Si4455 or Si4355) and reset the application. 2. Error message: Not supported radio! Connect a Si4x55 type RFpico then Reset! Cause: The connected RFpico board holds unsupported radio. Solution: Connect a supported EZRadio RFpico board (Si4455 or Si4355) and reset the application. 3. Error message: Not supported custom frequency band! Custom freq band mismatches with RFpico. Cause: Frequency band of the connected RFpico board mismatches with frequency band of the stored custom parameters. Solution 1: Change custom parameters with WDS to match with the connected RFpico board. Solution 2: Change the connected RFpico board to match with the stored custom parameters. Solution 3: Use selected parameters instead of the custom parameters. |
