Software Configuration Information

  1. Activating the audio amplifier
    a. un-mute all channels in alsamixer
    b. Enable Speaker PA via gpio114:
    c. Code Block
    sudo su
    cd /sys/class/gpio
    echo 114 > export
    cd gpio114
    echo out > direction
    echo 1 > value

  2. Adjusting Display options

  3. Selecting Coax inputs Note: The only valid configurations are when rfswitch1 is off and rfswitch2 is on, or the other way round.
    a. Selecting Direct SMA Code block
    sudo su
    cd /sys/class/leds/rfswitch1/
    echo 1 > brightness
    cd /sys/class/leds/rfswitch2/
    echo 0 > brightness

  4. Turn on Bias-Tee to the Coax Connector
    a. Code block for 14 volt dc at both sma input connectors
    sudo su
    cd /sys/class/gpio
    echo 119 > export
    cd gpio119
    echo out > direction
    echo 1 > value

  5. Adjusting SDR parameter
    ** RF Amplifier Gain
    ** Lora and other SX1281 parameters
    The default for the chat application found in main.cpp:
    modulationParams.PacketType = PACKET_TYPE_LORA;
    modulationParams.Params.LoRa.SpreadingFactor = LORA_SF7;
    modulationParams.Params.LoRa.Bandwidth = LORA_BW_0400;
    modulationParams.Params.LoRa.CodingRate = LORA_CR_4_5;
    PacketParams.PacketType = PACKET_TYPE_LORA;
    PacketParams.Params.LoRa.PreambleLength = 0x08;
    PacketParams.Params.LoRa.HeaderType = LORA_PACKET_VARIABLE_LENGTH;
    PacketParams.Params.LoRa.PayloadLength = 50;
    PacketParams.Params.LoRa.Crc = LORA_CRC_ON;
    PacketParams.Params.LoRa.InvertIQ = LORA_IQ_INVERTED;

The post above is a wiki. I believe anyone can edit it. Please do.


Outernet in L-Band no longer available?
#3

Least we loose this post, will it become something we can find easily on the Forum Home Page or within the Outernet Home page? Ken


#4

Yeah, once we have more content in this and the other wikis, I’ll add a link up top.


#5

Bumping this to get more information into the wiki.


#6

Maybe someone can come up / develop a standard formatting scheme. Involving a paragraph numbering, headings, bullets… My first try needs some help.
