Antenna Layout

HF-BL500 supports internal antenna. Customers need to obey following antenna design rules and module location suggestions:

  • For user PCB, place module on the edge area of the PCB as possible, or suspend the antenna area.

  • Module antenna correspondent area can’t put components or paste GND, the surrounding components or GND should be as far as possible from antenna place.

  • Antenna must be away from high components at least 10mm.

  • Antenna can’t be shielded by any metal enclosure.

High Flying suggests to locate HF-BL500 as following picture to reduce the influence to antenna and wireless signal as much as possible, or contact High Flying technique people for support

APPENDIX A: UART TRANSPARENT TRANSMIT

TYPICAL APPLICATION

Typical Application

BCTS—— Module UART output notify signal, output (wake up external MCU, remind MCU there is data output)
Module will pull down BCTS, and delay Xms before output data; X set by external MCU via At command, in default there is no latency. After sending data, BCTS pull-up, if there is new data sending BCTS will pull-up after sending all the new data. .

WAKE UP—— UART wakeup enable, Stop Mode Wakeup ,(recommend to add external Pull-up
resistor) Pin Mode: WAKEUP pin is high resistor input. Can’t be suspended, can be controller by pull-up or
pull down or external MCU
UART Wakeup Enable: when WAKEUP is pull-up, all system enter into DEEP SLEEP ; when WAKEUP is pull-down, system enter into SLEEP mode. When sending data from external MCU to module, need to pull-down WAKEUP pin, after sending finished, pull-up WAKE UP to lower the power.
There must be a latency from WAKE UP pull-down to MCU sending data, the time is no less than 2ms。

Stop Mode Wakeup:WAKEUP pull-down, AT command send out Stop command, when system enter into STOP mode, can be wake up through pull-up WAKE UP.

UART_TX/RX ——UART data send/receive signal。
Manufacture ——restore factory setting via hardware method: keep low level at least 5 second when power on or restore

Label and compliance information:
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
NOTE: The manufacturer is not responsible for any radio or TV interference caused by unauthorized
modifications or changes to this equipment. Such modifications or changes could void the user’s authority to operate the equipment.

Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

  • Reorient or relocate the receiving antenna.
  • Increase the separation between the equipment and receiver.
  • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
  • Consult the dealer or an experienced radio/TV technician for help.

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with a minimum distance of 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

The system integrator must place an exterior label on the outside of the final product housing the HFBL500-1 Module. Below are the contents that must be included on this label.
OEM Labeling Requirements:
NOTICE: The OEM must make sure that FCC labeling requirements are met. This includes a clearly visible exterior label on the outside of the final product housing that displays the contents shown in below:

Model : HF-BL500-1
Contains FCC ID: 2BDXL-BL5001

Information on test modes and additional testing requirements:
When testing host product, the host manufacture should follow FCC KDB Publication 996369 D04 Module Integration Guide for testing the host products. The host manufacturer may operate their product during the measurements. In setting up the configurations, if the pairing and call box options for testing does not work, then the host product manufacturer should coordinate with the module manufacturer for access to test mode software.

Additional testing, Part 15 Subpart B disclaimer:
The modular transmitter is only FCC authorized for the specific rule parts (FCC Part 15.247) list on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed when contains digital circuitry.

Note EMI Considerations

The host responsible party integrator must perform EMC tests on the module during synchronous transfer operations when integrating on the host. If there are no emissions of increased magnitude and/or different frequencies compared to the data reported in the module authorization, there is no need to submit the results of these simultaneous transmission test data.
KDB publication 996369 D02 and D04 for guidance on module integration and best practices.
Co-launching with other modules can refer to KDB publication 996369 D02 and D04, while allowing the host manufacturer to confirm compliance

How to make changes
This module is stand-alone modular. If the end product will involve the Multiple simultaneously transmitting condition or different operational conditions for a stand-alone modular transmitter in a host, host manufacturer have to consult with module manufacturer for the installation method in end system.
