CHANGELOG - obnizOS - obniz Docs

7.1.0 (Under beta)

2026/x/x

This release expands the Lua Plugin with new peripherals and system functions, and improves cellular connectivity and board startup. Several peripheral functions that previously required the ESP32 family now also run on obniz Board, because the Lua peripheral layer was moved onto logical IO mapping.

Target OS

obnizOS for Intelligent Edge Kilo ( hw=iekilo1 )
obnizOS for Intelligent Edge Micro ( hw=iemicro1 )
obnizOS for obniz BLE/Wi-Fi Gateway Gen 2.0 ( hw=blewifi_gw2 )
obnizOS for obniz BLE/LTE Gateway (Cat.4) ( hw=blelte_gw2 )
obnizOS for AK-030 LTE Cat.M1 USB Dongle ( hw=ak030 )
obnizOS for obniz BLE/Wi-Fi Gateway ( hw=encored )
obnizOS for IoTBank USB Gateway ( hw=iotbankusbgw )
obnizOS for M5Stack Basic ( hw=m5stack_basic )
obnizOS for ESP32 ( hw=esp32w or hw=esp32p )
obnizOS for obniz Board 1Y ( hw=obnizb2 )
obnizOS for obniz Board ( hw=obnizb1 )

Plugins (Lua)

New peripherals

PWM: Added pwm.start(), pwm.freq(), pwm.duty(), and pwm.stop(). Output is specified by logical obniz IO, so the same code runs on obniz Board as well.
Display: Added display.print(), display.clear(), and display.raw(). These are ignored on products without a display.
LTE: Added lte.at() for sending arbitrary AT commands to the cellular modem.

IO and analog

IO: Added io.drive() (output drive method) and io.pull() (pull resistor). "5v" is available only on obniz Board.
AD: ad.get() now also runs on obniz Board.
UART / SPI: Added uart.isUsed() and spi.isUsed(). UART and SPI now operate through logical IO, so they are available on obniz Board.

Cloud and communication

Cloud transaction: Added cloud.transactionWait(), paired with the obniz.js obniz.plugin.callWait() method and the obniz.plugin.onCloudTransaction handler, for request-and-reply communication.
Error handling: Added the obniz.plugin.onError event to receive Lua errors on the obniz.js side.

System

Low memory: Added the on_low_memory() handler, called before an allocation fails so the plugin can release resources and recover.

Bluetooth

Added the isScanResp flag to BLE scan results, which indicates whether a packet is a scan response.

Peripherals

PWM: Added PWM support for ESP32-C3 and ESP32-C6.

Internet Connection

LTE

nRF9160: Enabled the TLS session cache.
nRF9160: Added an LTE-M only mode.
Improved connection compatibility with 1NCE SIM.

System

Improved the obniz Board startup screen.
