the reference design is under NDA from semtech, but you cand find schematic at http://ww1.microchip.com/downloads/en/DeviceDoc/40001827A.pdf or you can look at the pico gateway reference design, it is almost the same adding a STM32 MCU http://www.semtech.com/apps/filedown/down.php?file=sx1308p868gw_picocell_gtw_e381v02b_eu_folder.zip
@nestorayuso thank you so much. I noticed that the pico gateway use SX1308 not SX1301, there is some question about this:
Thanks again for your help ,I am the fresh ...
both are basically the same, only changes in operational temperature range and power requirements.
in gateway reference design, both software modules lora-gateway and packet_forwarder run on linux platform (raspberry-pi for example), and a low-latency/high speed SPI is needed (USB was avoided). in pico-gateway reference design, the lora-gateway software module runs on a STM32 and packet_forwarder run on linux platform (raspberry-pi for example), in this case, low-latency/high speed SPI is used between SX130x and STM32, and UART/USB CDC between STM32 and raspberry-pi because latency is not critical now.
@nestorayuso thank you so much~~~ It seems that pico-gw have better performance than SX1301.
@nestorayuso the packet_forwarder need server, if i just install the server on my raspberry-pi for test, which server software can i use ?
thank you.
@nestorayuso I have review the picoGW-mcu code, and find the mcu can use UART or USB to connect with RPi: `#ifdef USE_UART CMDMANAGER::CMDMANAGER(PinName Tx, PinName Rx) { kill = false; ActiveInterface = (INTERFACE *) new COMUART (Tx, Rx); ActiveCom = ISUARTINTERFACE; }
CMDMANAGER::CMDMANAGER(PinName Tx, PinName Rx) { kill = false; ActiveInterface = (INTERFACE *) new COMUSB (); ActiveCom = ISUSBINTERFACE; }
But in the code of picoGW_packet_forwarder, only UART (/dev/ttyACM0) can be used,no USB,
Why ???
#define COM_PATH_DEFAULT "/dev/ttyACM0"
If the picoGW_mcu is compiled in USB mode, when inserted on the USB port it will be mounted on /dev/ttyACM0 on the RPi. Even though it is USB, it is a serial device.
Anyway, you can indicate to the packet forwarder which device to be used with -d option. Use dmesg to get the device asssociated to the picoGW.

Link broken. Anybody, can send me?
anybody could tell me ?
how can i get the demo board or the Schematic diagram ?
Thank you so much...
