Hi @berkseo. Thanks for the suggestion, but could you describe in more detail? As for my TODO list, there is already a task to add 485 interface to the gateway. My latest device "xRoom" have this interface. ps/ Where have you gone? I have been working on "xRoom" shield. A small announce: Do you remember the discussion about multinode? So, it will be available soon))

Hello, I'm thinking about upgrading this board to include pinout for LIS3DH breakout board, like this one : https://www.aliexpress.com/item/LIS3DH-Three-Converters-Motion-Accelerometer-Triaxial-Acceleration-Temperature-Sensor-Module-Development-Board-Replace-ADXL345/32840326778.html and ditch the ADXL shield as it's not a good solution, it has either the ADXL345 which uses too much power, or the ADXL362 which is ultra low power but lacks advanced functionality like tap/double tap detection. I would like to have feedback of users on this (do it sound useful ?), and also know if anyone uses the SMD footprints on the board, for leds and for reserve capacitors, as it could be a cleaner board without those footprints. I would make the following changes : put footprint for LIS3DH accelerometer along the "NModule connector" as it has too many pins to put elsewhere keep only one I2C footprint on the side, for "GY-49" MAX44009 light sensor breakout board: https://www.aliexpress.com/item/GY-49-MAX44009-Ambient-Light-Sensor-Module-for-Arduino-with-4P-Pin-Header-Module/32828654450.html temperature/humidity would be via the existing "SMD" footprint, it's not through hole but very easy to solder as it's 2.54mm pad spacing remove SMD footprints for LED, add footprint for through hole reserve capacitor, keep SMD footprints for reserve capacitors only if I have space for them shield would be a bit extended to go over the 2 M2 holes in the "power" part of the NModule, so it could be fitted with spacers and nylon screws and have stable/reliable mechanical connection between NModule and Shield. Basically this would be the footprint of the shield : So in the end it would make one shield to have Temperature/Humidity/Light/Acceleration or Temperature/Humidity/Light/Door.

@Tommas Hi, now I've posted a device for sale on Tindie, if it's still relevant for you https://www.tindie.com/products/avikmen/usb-rf-gateway-with-stm32-and-nrf24-in-case/

Actually, I use the FTDI connector on my outdoor weather sensor to power it from the solar/Li-Ion charger board. Used angled headers to keep the height down. I'll try to post a picture asap.

@5546dug Yes I think you need 1.4.1 or latest. The messages you see (0;0;3;9...) are traffic in the wireless sensor network. My problem appeared again. The EthernetGateway responds to Ping but Vera plugin says: "Cannot send command - communications error" So perhaps increasing power could help, but how? Is adding capacitors enough?? Like for the radio there already is one..

@jesse said: I found the solution on this page: http://mathertel.blogspot.com/2013/04/using-spi-bus-with-ethernet-sd-card-and.html The key is setting the Chip Select (CS) line to be different for each module. For the CC3000... "#define ADAFRUIT_CC3000_CS 7" Pin 7 is being used exclusively to select the Wifi module. https://learn.adafruit.com/adafruit-cc3000-wifi/cc3000-breakout For the NRF24L01+... "RF24 radio(9,10);" Pin 9 is being used for Chip Enable (CE) and Pin 10 is Chip Select (CS). http://arduino-info.wikispaces.com/Nrf24L01-2.4GHz-HowTo http://maniacbug.github.io/RF24/classRF24.html The other SPI pins: CLK, MISO, MOSI, are shared by the two modules and get wired in parallel. Hi do you still have a Gateway code when using CC3000 and arduino Mega or UNO(if it fits)?
