BLESTM32VE Bluetooth Module
Introduction
BLESTM32VE is a Bluetooth module designed by Victron Energy B.V. and is meant to be used only within Victron Energy B.V. product range. It will be mounted within the enclosure of our products and won’t be visible or accessible from the end user. It won’t be sold to end users directly.
Description
The module uses the STM32WB55CEU6 multiprotocol wireless and ultra-low-power device that embeds a powerful and ultra-low-power radio compliant with the Bluetooth® Low Energy SIG specification 5.3 and with IEEE 802.15.4-2011. It contains a dedicated Arm® Cortex®-M0+ for performing all the real-time low layer operation. For more detailed information on the MCU used, please refer to its datasheet (https://www.st.com/stm32wb55xx).

(1) The maximum polarization dependent EIRP is 3.5 dBm in the horizontal plane. This is the highest EIRP value for
the highest frequency dependent correlated antenna gain and output power.
(2) The measurement of the EIRP gives a maximum value of 3.5 dBm in the horizontal plane. The conducted RF-
output power (Pcond) was measured as 3.5 dBm. The maximum isotropic antenna gain is calculated as:
3.5 dBm EIRP 3.5 dBm Pcond = 0 dBi Antenna gain

Host integration considerations
For the RED in the European Union, it is advised to test the host for at least the following clauses from article 3.2 [EN 300 328 v2.2.2]:
· Clause 4.3.2.2: RF output power, consider this test for the following conditions. o If the antenna is potted o If the enclosure is metallic
· Clause 4.3.2.9: TX radiated Spurious emissions, · Clause 4.3.2.10: RX radiated Spurious emissions. *check with the test house if any particular tests need to be performed for each host.

Labeling and Information requirements
· United States (FCC)
As the module will be installed within the final product, its FCC ID number won’t be visible. Thus, it is required that the outside of the final product must display a label referring to the enclosed module. On the exterior label, wording as stated below can be used:
Contains Transmitter Module FCC ID: 2A2XGBLESTM32VE or Contains FCC ID: 2A2XGBLESTM32VE
A user’s manual of the final product must include the following statement:
Compliance Statement (Part 15.19) 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.
Warning (Part 15.21) Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
FCC Interference Statement (Part 15.105 (b)) 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 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.
RF exposure warning To comply with FCC and Industry Canada RF radiation exposure limits for general population/uncontrolled exposure, the antenna(s) used for this transmitter must be installed such that a minimum separation distance of 20 cm is maintained between the radiator (antenna) and all persons at all times and must not be co-located or operating in conjunction with any other antenna or transmitter.”
