What’s New and Versions

Change log, new features and improvements for Rinho firmware.

Firmware updates are performed remotely via FOTA.

Version 1.9.27 - Pre-release (since August 17, 2026)

Series in progress: delivered via FOTA on request, not yet the stable version recommended for the whole fleet. The features listed below are implemented and validated on the bench and in vehicles; the delivery number (T) advances as fixes are added.

🆕 New Features

TRIP histogram band signals (FRP / FVL / FAC / FTB / FTM) — Histograms

  • Every RPM, speed, accelerator, turbo and temperature band is an events-engine trigger, with the same index QTPR reports: TRG=FRP05+ fires on entering 1400-1599 rpm
  • Fixed ~1.3 s latency with no UV to configure: a 1 s dwell against bouncing between neighbouring bands, and no events while the CAN bus is silent
  • EVAL functions FRP(n)…FTM(n) and query >QSSFRP05<; present in every model

ECU fault code reading — DTC (CXDTC)

  • The device goes from reporting whether the vehicle has faults to reporting which ones, with the same detail as a workshop scan tool
  • J1939 (trucks and machinery): SPN, FMI, reporting ECU, occurrence count and dashboard lamps — including multi-packet messages (BAM) and several ECUs at once
  • OBD2 (light vehicles): the full standard code (P0301, P0420, U0100) with the reporting ECU — validated in a vehicle
  • Automatic report on new fault or resolution, carrying the date and time of the moment the fault occurred: DF report
  • On-demand query with >QDTC<, >QDF< and >GDF00H<
  • DTC00-DTC03 signals for the event engine, EVAL functions DTCN() / DTC(n) / DTCH(spn) and the 'DTC' token for user reports
  • Configurable report destination (cellular, WiFi, Bluetooth, serial, backup or internal datalog)

Automatic APN (SCXAA)

  • A device with no APN configured gets its own by asking the network: no more looking up the operator’s APN and loading it device by device
  • If an APN is already configured nothing is touched: no device in service changes behaviour
  • Validated with four SIMs from four providers, two of them in international roaming

Technoton DUT-E S7 / 2Bio S7 fuel level sensor (BLE, type 50)

  • Frequency, temperature, level, volume and fault mask from the BLE advertisement
  • Abrupt fuel drop detection with UV type X triggers, with no extra code

Remote update diagnostics and control (QFRM / SFRMB)

  • >QFRM< reports the full state of the anti-brick system, including the fallback version the device is holding: it allows sweeping a whole fleet and spotting devices at risk before a complaint
  • >SFRMB1< manually blesses the installed firmware; anything installed manually is protected from the first boot

🔧 Improvements

Trip speed with automatic fallback (TRIP)

  • TRIP speed now uses an ECU05 → ECU15 → GPS fallback chain: fleets whose vehicles publish speed over wheel speed (CCVS) now fill their speed bands correctly

Reports from one event share the same timestamp

  • All actions of an SRL rule go out with identical date and time, even if execution crosses a second boundary: server-side grouping by timestamp stops breaking

Safer remote updates

  • The automatic rollback checks that the fallback version is compatible with the memory layout in use before jumping to it
  • Blessing of new firmware now has two levels (15 and 60 minutes) and can be granted manually

Version 1.9.26 - August 16, 2026

🆕 New Features

Bluetooth link between Rinho devices (CXBTH)

  • One device can connect to another as a client: >SCXBTH1,<name>,<pin>,<timeout>,<peer><
  • TOFU pairing (the MAC is pinned on the first authenticated pairing) and roaming mode to latch onto the first available device
  • Automatic reconnection and status via >QBTH< (link role and state)
  • Use case: a trailer or hopper reporting through the tractor

Configurable virtual ignition thresholds (SCXIGNV / QCXIGNV)

  • Voltage detection thresholds are no longer fixed: >SCXIGNV1,<on>,<off><, with 0 to return to automatic
  • >QCXIGNV< reports the effective thresholds and the current voltage — useful on vehicles with shifted ranges
  • See Virtual Ignition

Remote WiFi network scan (QWIFN)

  • Lists the networks visible from the device with SSID, RSSI and channel, flagging the ones already configured
  • Lets you solve a WiFi installation without going on site

Bluetooth client connected signal (BTH)

  • New signal for the event engine and EVAL: rules can trigger on whether a BLE client is connected

Idle fuel consumption (TRIP)

  • The trip report now includes fuel burned with the vehicle stopped and the engine running (IDLEFUEL)

Datalog download by date range (QDL)

  • QDL accepts a full date range, without treating the time as a daily window

🔧 Improvements

Bluetooth: steadier links and complete frames

  • MTU negotiation on connect (256 bytes) with chunking and reassembly: frames over 20 bytes no longer arrive split
  • With a wrong PIN the device stops retrying indefinitely: three failed attempts and a 60-second back-off
  • A peer longer than the allowed maximum now returns an error instead of being silently accepted

Full restore when leaving low-power mode

  • Returning from KO++ restores Bluetooth, WiFi and accessory power in every case: the CAN bus reads again after external power is cut and restored

Background WiFi updates

  • Firmware download over WiFi runs in its own task: it no longer blocks command processing on slow links

More efficient report acknowledgements

  • ACK handling moves to a queue with its own retry clock: a server delay no longer triggers unnecessary channel switching

VIN over J1939

  • VIN reading on trucks via multi-packet reassembly, with bounded retries

Voice call on Smart IoT

  • Fixes volume and dialling/answering delay on devices with the EG915U modem

Version 1.9.25 - August 3, 2026

🆕 New Features

Dynamic actions — SDA / QDA (DA Command)

  • Run a template with UC syntax written inline, without using a user report slot
  • >QDA <template>< builds the text and returns or routes it; >SDA <template>< also executes the resulting command
  • Optional destination with ;@DEST (cellular, WiFi, Bluetooth, serial, SMS, datalog or backup) and the ! ephemeral-send modifier
  • Transparent response: >QDA QIO< answers exactly like a direct QIO, with no added prefix

Pulse burst counter (PB)

  • The device counts pulse bursts and exposes count, sequence and age for rules and reports (MPB(p;t))
  • Full configuration in a single line and counter reset with >SPB<i>Z<, without rebooting the device
  • New PB trigger for the event engine

Ephemeral send in the report generator (G Command)

  • ! modifier: a single immediate attempt, no queue — ideal for presence signals that make no sense to retry

Queue label in the datalog (SCXTAIP)

  • Third labelMode parameter: adds the ;#LOG:<num>; label to reports coming out of the LOG queue, to tell them apart on the server

Outgoing voice call (SVCC)

  • Full implementation of the device-initiated voice call

🔧 Improvements

Stable digital inputs with degraded supply

  • With supply voltage between 3 and 5 V the digital inputs freeze at their last valid state, avoiding false alarms while the vehicle cranks or the battery recovers

Wider range for TRIP histograms

  • Time histograms move to second resolution: the ceiling rises from 11 minutes to 18 hours
  • New engine temperature histogram

Report destination validation (SIP)

  • SIP validates the destination format and returns an error instead of accepting an invalid address that left the channel mute
  • WiFi backup no longer loses transmissions when a single backup IP is configured

Version 1.9.24 - June 13, 2026

🆕 New Features

  • Automatic cellular registration ladder (COPS/CEREG): the device reaches the network with no manual tuning

  • Real LTE signal quality: RSRP, RSRQ and SINR
  • Field coverage diagnostics without external instruments

DFOTA — Remote modem update (SCFW / QCFW)

  • Remotely updates the firmware of the cellular modem itself
  • SCFW"<url>.pack" triggers the download; QCFW reports phase and percentage
  • Updates the modem remotely, without a technical visit

  • >QDL+,A<: dumps the full log for forensic event recovery
  • Combinable with a date range
  • Ideal for post-incident analysis

Send a complete trip to a destination (STP,SEND)

  • >STP,SEND;@destination<: synthesizes and sends the full trip (summary, histograms, score and global stats)
  • Part selection via composable flags
  • Full payload, no character truncation

🔧 Improvements
