Drawing 3-1 SPI Timing Sequence 4. Frequently Asked Questions 4.1 The communications cannot be made if the module is at close range ⚫ To verify whether the sending and receiving configurations are matching and the communications cannot be made if the configurations are different. ⚫ The voltage is abnormal; and the transmission will be abnormal if the voltage is too low. ⚫ The battery is low; and the transmission will be abnormal if the voltage is lowered due to the low volume battery. ⚫ The RF signal does not reach the antenna or π circuit soldering occurs error if antenna welding is abnormal. 4.2 Module communication distance is not enough ⚫ The power transmitted is small due to bad antenna impedance matching. ⚫ Objects such as metal around the antenna or the metal inside the module may cause serious signal attenuation. ⚫ Any other interference signals in the test environment may cause the module to communicate close. Page 8 of 15

Leader in IOT Embedded Solution ⚫ Insufficient power supply will make the module’s transmit power abnormal. ⚫ Harsh test environment will make signal attenuation greater. ⚫ When the module communicates with other end after passing through the wall, the wall will have a great impact on signal attenuation. The signal will be attenuated greatly when most of signals are passing through the wall. ⚫ If the module is too close to the ground, resulting in poor communication due to being absorbed and reflected. 5. Notation of Annexes 1. Recommended to use DC stabilized power supply to power for the module. The power ripple coefficient should be as close as possible and the module needs to be reliably grounded. Please be noted that the positive and negative poles of power supply shall be correctly connected. The module may be permanently damaged if connected reversely. 2. Prohibited to have any metal objects around the module antenna. Otherwise, the communication distance may be seriously affected. Page 9 of 15

Leader in IOT Embedded Solution 2.9 Information on test modes and additional testing requirements a) The modular transmitter has been fully tested by the module grantee on the required number of channels, modulation types, and modes, it should not be necessary for the host installer to re-test all the available transmitter modes or settings. It is recommended that the host product manufacturer, installing the modular transmitter, perform some investigative measurements to confirm that the resulting composite system does not exceed the spurious emissions limits or band edge limits (e.g., where a different antenna may be causing additional emissions). b) The testing should check for emissions that may occur due to the intermixing of emissions with the other transmitters, digital circuitry, or due to physical properties of the host product (enclosure). This investigation is especially important when integrating multiple modular transmitters where the certification is based on testing each of them in a stand-alone configuration. It is important to note that host product manufacturers should not assume that because the modular transmitter is certified that they do not have any responsibility for final product compliance. c) If the investigation indicates a compliance concern the host product manufacturer is obligated to mitigate the issue. Host products using a modular transmitter are subject to all the applicable individual technical rules as well as to the general conditions of operation in Sections 15.5, 15.15, and 15.29 to not cause interference. The operator of the host product will be obligated to stop operating the device until the interference has been corrected. Below are steps for TX verification： RfTest(); // RF parameter configuration STX(); //Set RF to send mode SIDLE() // Set RF to IDLE mode ,stop sending data 2.10 Additional testing, Part 15 subpart B disclaimer The final host / module combination need to be evaluated against the FCC Part 15B Page 13 of 15

Leader in IOT Embedded Solution criteria for unintentional radiators in order to be properly authorized for operation as a Part 15 digital device. The host integrator installing this module into their product must ensure that the final composite product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules, including the transmitter operation and should refer to guidance in KDB 996369. Frequency spectrum to be investigated For host products with certified modular transmitter, the frequency range of investigation of the composite system is specified by rule in Sections 15.33(a)(1) through (a)(3), or the range applicable to the digital device, as shown in Section 15.33(b)(1), whichever is the higher frequency range of investigation. Operating the host product When testing the host product, all the transmitters must be operating.The transmitters can be enabled by using publicly-available drivers and turned on, so the transmitters are active. In certain conditions it might be appropriate to use a technology-specific call box (test set) where accessory devices or drivers are not available. When testing for emissions from the unintentional radiator, the transmitter shall be placed in the receive mode or idle mode, if possible. If receive mode only is not possible then, the radio shall be passive (preferred) and/or active scanning. In these cases, this would need to enable activity on the communication BUS (i.e., PCIe, SDIO, USB) to ensure the unintentional radiator circuitry is enabled. Testing laboratories may need to add attenuation or filters depending on the signal strength of any active beacons (if applicable) from the enabled radio(s). See ANSI C63.4, ANSI C63.10 and ANSI C63.26 for further general testing details. The product under test is set into a link/association with a partnering WLAN device, as per the normal intended use of the product. To ease testing, the product under test is set to transmit at a high duty cycle, such as by sending a file or streaming some media content. Page 14 of 15
