ASR Microelectronics ASR605x

Configuration:platform = asrmicro650x

ASR Microelectronics ASR605x series is highly intergrated and ultra low power SoC based on the PSoC 4000 series MCU (ARM Cortex M0+ Core) and Semtech SX1262 transceiver.

For more detailed information please visit vendor site.



LoRaWAN protocol can be configured in “platformio.ini” (Project Configuration File) using the following syntax board_build.arduino.lorawan.* where * is an option from the following list:

Option Description Possible values Default
region Region definition AS923, AU915, CN470, CN779, EU433, EU868, KR920, IN865, US915, US915_HYBRID AS923
class Device class CLASS_A, CLASS_C CLASS_A
netmode Activation method OTAA, ABP OTAA
adr Adaptive Data Rate ON, OFF ON
uplinkmode Uplink confirmed/unconfirmed messages CONFIRMED, UNCONFIRMED CONFIRMED
net_reserve Don’t rejoin after reset ON, OFF OFF
at_support AT commands support ON, OFF ON
rgb RGB light for LoRaWAN status ACTIVE, DEACTIVE ACTIVE
debug_level Print LoRaWAN relevant messages print to serial port NONE, FREQ (Sending/receiving frequency), FREQ_AND_DIO (Sending/receiving frequency and DIO pin interrupt information) NONE


platform = asrmicro650x
framework = arduino
board = cubecell_board
board_build.arduino.lorawan.region = EU433
board_build.arduino.lorawan.adr = OFF
board_build.arduino.lorawan.debug_level = FREQ_AND_DIO

More information about LoRaWAN configuration can be found in the official CubeCell documentation.
