If a Base Board support an SDIO interface, it must be able to be shared with an SPI Master interface. 4. The Accessory Port interface is not 100% compatible with the PCIe standard. The PCIe channel has been replaced with an SPI/SDIO interface, and additional voltage are being supplied. 5.

Kiwi-tec Confidential Documentation 8 2. Software Setup TLM991 can only be used on Linux-based operating system. For driving TLM991 on Linux, the source code of TLM991 can be download from https://github.com/Lora-net/lora_gateway. Please use the following command to download the source code. Note that, due to FDTI’s SPI interface being removed, the source code above v3.2.0, including v3.2.0, would not work with TLM991. # git clone https://github.com/Lora-net/lora_gateway.git # cd lora_gateway # git checkout -b v3.1.0 Before building the source code, some modification is needed for driving TLM991: 1. Editing libloragw/library.cfg CFG_SPI= ftdi 2. Editing libloragw/src/loragw_spi.ftdi.c, changing following a = PinHigh(mpsse, GPIOL1); b = PinLow(mpsse, GPIOL1); to a = PinLow(mpsse, GPIOL1); b = PinHigh(mpsse, GPIOL1); The last step is installed libftdi and related header files on host operating system. Then, you can proceed to compile the source code. More detail can also be founded on https://github.com/mirakonta/lora_gateway/wiki. Notice: Any changes or modifications not expressly approved by the party responsible for compliance could void your 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 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. This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. For a host using a certified modular with a standard fixed label, if (1) the module’s FCC ID is not visible when installed in the host, or (2) if the host is marketed so that end users do not have straightforward commonly used methods for access to remove the module so that the FCC ID of the module is visible; then an additional permanent label referring to the enclosed module: “Contains Transmitter Module FCC ID: 2AKIBTLM991 ” or “Contains FCC ID: 2AKIBTLM991 ” must be used. The host OEM user manual must also contain clear instructions on how end users can find and/or access the module and the FCC ID.
