## Config file for RPi-LoRa-KISS-TNC 2nd generation

## Lora Module selection

## Display enable and font
disp_en = False
font_size = 8

## Log enable and path
log_enable = True
logpath='/var/log/lora/lora.log' #log filename. Give r/w permission!

## KISS Settings
# Where to listen?
# TCP_HOST can be "localhost", "0.0.0.0" or a specific interface address
# TCP_PORT as configured in aprx.conf <interface> section
TCP_HOST = "0.0.0.0"

## Hardware Settings
# See datasheets for detailed pinout.
# The default pin assignment refers to PCB designed by I8FUC.
# The user can wire the module by his own and change pin assignment.
# assign "-1" if the pin is not used

# Settings valid for both SX126x and SX127x

csId = 0 #SPI Chip Select pin. Valid values are 0 or 1
irqPin = 5 #DIO0 of sx127x and DIO1 of sx126x, used for IRQ in rx

# Settings valid only for SX126x. Default pin assignment refers to the PCB schematic /doc/LoRa_RPi_Companion_2022.pdf
resetPin = 6
busyPin = 4
# If txen and rxen are disabled (=-1), then DIO2 will be set as RF Switch control
txenPin = 0 #In Ebyte modules, it's used for switching on the tx pa.
rxenPin = 1 #In Ebyte modules, it's used for switching on the rx lna

# If Lora module has a TCXO, the following parameter must be True
# If True, the DIO3 line will be set as control voltage of the TCXO
