However, the average current consumption is only around 230 μA, while advertising at an interval of approximately 100 ms, see Figure 5-2. This is due to the “Reduced Current Consumption” low-power mode being enabled (configuration parameter - UART_RX_IND). Reducing the current draw to approximately 60 μA, while not actively transmitting the advertisings packets, refer to the “ _BM70/71 Bluetooth[®] Low Energy Module User’s Guide”_ (DS50002542) for more details. The overall average current consumption is measured with a 3.3V VBAT input, and is affected by the way the IS1870/71 IC on the BM70/71 module has been configured to operate. A low average current value can be achieved by choosing the minimum settings for the advertising interval and connection interval, which meet the data throughput requirements of the intended application. The lower or less frequent the interval time periods, the lower the overall average current to be drawn. ## **FIGURE 5-1: TX/RX PEAK CURRENT CONSUMPTION OF AN ADVERTISING EVENT** DS60001372F-Page 40  2015-2017 Microchip Technology Inc. **BM70/71** Figure 5-2 illustrates the oscilloscope screen, captured when the auto operation and Low-Power mode is active on the BM70/71 module.

This transmitter is restricted for use with the specific antenna(s) tested in this application for Certification and must not be co-located or operating in conjunction with any other antenna or transmitters within a host device, except in accordance with FCC multi-transmitter product procedures. This module is approved for installation into mobile or/and portable host platforms ## A.1.4 HELPFUL WEB SITES Federal Communications Commission (FCC): http://www.fcc.gov FCC Office of Engineering and Technology (OET) Laboratory Division Knowledge Database (KDB): http://apps.fcc.gov/oetcf/kdb/index.cfm. ## **A.2 Canada** The BM70/71 module has been certified for use in Canada under Industry Canada (IC) Radio Standards Specification (RSS) RSS-247 and RSS-Gen. Modular approval permits the installation of a module in a host device without the need to recertify the device. ## A.2.1 LABELING AND USER INFORMATION REQUIREMENTS Labeling Requirements for the Host Device (from Section 3.1, RSS-Gen, Issue 4, November 2014): The host device shall be properly labeled to identify the module within the host device. On BM71 module, due to the limited module size (9.0 mm x 11.5 mm) the IC identifier is displayed in the data sheet only and cannot be displayed on the module label. The Industry Canada certification label of a module shall be clearly visible at all times when installed in the host device, otherwise the host device must be labeled to display the Industry Canada certification number of the module, preceded by the words “Contains transmitter module”, or the word “Contains”, or similar wording expressing the same meaning, as follows: For the BM70 module: Contains transmitter module IC: 12246A-BM70BLES1F2 For the BM71 module: Contains transmitter module IC: 12246A-BM71S2 User Manual Notice for License-Exempt Radio Apparatus (from Section 8.4, RSS-Gen, Issue 4, November 2014): User manuals for license-exempt radio apparatus shall contain the following or equivalent notice in a conspicuous location in the user manual or alternatively on the device or both: This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes: (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. DS60001372F-Page 56  2015-2017 Microchip Technology Inc. **BM70/71** Transmitter Antenna (from Section 8.3, RSS-Gen, Issue 4, November 2014): User manuals for transmitters shall display the following notice in a conspicuous location: Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. The preceding notice may be affixed to the device instead of displayed in the user manual. ## A.2.2 RF EXPOSURE All transmitters regulated by IC must comply with RF exposure requirements listed in RSS-102 - Radio Frequency (RF) Exposure Compliance of Radio communication Apparatus (All Frequency Bands). ## A.2.3 HELPFUL WEB SITES Industry Canada: http://www.ic.gc.ca/ ## **A.3 Europe** The R&TTE Compliance Association provides guidance on modular devices in the document “ _Technical Guidance Note 01”_ which is available for download from the following location: http://www.rtteca.com/html/download_area.htm. To maintain conformance to the testing listed in Table A-1 **/** Table A-2: European Compliance Testing, the module shall be installed in accordance with the installation instructions in this data sheet and shall not be modified. When integrating a radio module into a completed product the integrator becomes the manufacturer of the final product and is therefore responsible for demonstrating compliance of the final product with the essential requirements of the R&TTE Directive. ## A.3.1 LABELING AND USER INFORMATION REQUIREMENTS The label on the final product which contains the BM70/71 module must follow CE marking requirements. The R&TTE Compliance Association **Technical Guidance Note 01** provides guidance on final product CE marking. ## A.3.2 ANTENNA REQUIREMENTS From the R&TTE Compliance Association document Technical Guidance Note 01. Provided the integrator installing an assessed radio module with an integral or specific antenna and installed in conformance with the radio module manufacturer's installation instructions requires no further evaluation.Under Article 3.2 of the R&TTE Directive and does not require further involvement of an R&TTE Directive Notified Body for the final product. [Section 2.2.4] The BM70/71 module is an R&TTE Directive assessed radio module that is CE marked and has been manufactured and tested with the intention of being integrated into a final product. The BM70/71 module has been tested to R&TTE Directive 1999/5/EC Essential Requirements for Health and Safety (Article (3.1(a)), Electromagnetic Compatibility (EMC) (Article 3.1(b)), and Radio (Article 3.2) and are summarized in Table A-1 **/** Table A-2 **.** A Notified Body Opinion has also been issued.
