Two Suntech devices added: ST3940 and ST3940B

Suntech protocol updated: 1. ST600R : MSR command reply parsing fixed 2. ST310U : ALT packet parsing fixed

Suntech protocol updated: ST310U : gsm.lac and gsm.bsic parameters parsing fixed ST410 : ALT report parsing fixed

New settings added for Suntech ST600V , ST600R , ST630 , ST640 , ST640LC devices. Actions tab: Request Status and Reboot Input/Output tab: Enable/Disable Output 1 , Output 2 and Output 4

New settings Odometer and Hour Meter are added on Actions tab Applicable for the following devices Suntech ST600V Suntech ST600R Suntech ST640 Suntech ST640LC Suntech ST630 Suntech ST310U Suntech ST340 Suntech ST340LC(4pin) Suntech ST340R Suntech ST300 Suntech ST300A Suntech ST300R Suntech ST300B Suntech ST300V Suntech ST300C Suntech ST300K Suntech ST300P Suntech ST300F Suntech ST300D Suntech ST300H

Suntech ST300R : fixed parsing of GSM CELL field

Assigned headers are supported for suntech protocol. Applicable for the devices that work over universal protocol , e.g. Suntech St4340

Suntech ST3940 and Suntech ST3940B : fixed parsing of PWR_VOLT field for Status, Emergency and Alert reports. Now this field's value is stored into parameter battery.level

[Changelog] suntech protocol

bird

Fixed DTC medium header parsing — DTC format is now determined by VEH_PROT (vehicle protocol type) instead of first-byte heuristic. Resolves crash for J1939 DTCs with OC=0.
New J1708 DTC format support (VEH_PROT=2) with pid, fmi, oc fields in can.dtc array.

bird

Fixed network setting command lifecycle for st3xx devices - command was resent repeatedly after successful device response.

bird

Fixed DEX (serial_port) command response handling for Universal Protocol devices - commands now complete correctly instead of retrying until max_attempts exceeded.

bird

Fixed BBR (BLE Battery Report) parsing when the report is sent as the first packet on a TCP connection for ST4315B-family devices.

Added SD8000U model identification in Universal reports.

Added parsing for Universal ALT alerts: Voice Call (67), BLE Device Connection/Disconnection (170), D_BLE Fuel Low/High (174/175), D_BLE Door Tamper (179), and D_BLE Hall Detected (183). New parameters: ble.device.connected.status, ble.sensor.tamper.status.

baja

Fixed trip.engine.motorhours (TRIP_H_METER), which was stored in seconds instead of hours. The corrected value is previewed now in trip.engine.motorhours.hours; trip.engine.motorhours switches to hours on June 17, 2026.

bird

New parameter box.status is registered for Alert ID 162 (Carton Box Opened) and Alert ID 167 (Carton Box Closed): true when the box is opened, false when it is closed.

ST400 and ST410 alert reports now register the alert cause as the parameter it describes:
box.status when the carton box is opened, gsm.jamming.event on jamming detection, and the
new rf.device.present.status when a monitored RF device goes absent (false) or is recovered (true).
operating.mode.enum is removed from ST400 and ST410 alert reports; the status reports of those
devices continue to register it unchanged.

bird

New parameter rs232.connection.status added for ST8300V (RS232 connect/disconnect alert).

bird

Small Assign header 24 is now registered as battery.level (remaining battery capacity, percent) instead of battery.voltage. The value was always a percentage; the previous parameter declared volts.

ST4230 now parses trailing assigned-header fields from the assign map declared in its device settings, for reports that omit the ASSIGN_MAP field.

bird

Corrected Small Assign header 24 mapping: battery.level for ST4230, ST4280 and ST4290 by default; battery.voltage for other device types.

bird

Fixed parsing of RPT responses for ST300, ST300A, ST300R, ST300B, ST300V, ST300C, ST300K, ST300P, ST300F, ST300D, ST300H, ST310U, ST330, ST215, ST240, ST340, ST340LC(4pin), ST340R, ST340UR, ST340US, ST600V, ST600R, ST630, ST640, ST640LC, ST3940, ST3940B, ST4940, ST4940B.

bird

Bugfix in medium assigned headers: fixed crash on FFFFFFFF (inactive) values for headers 21 (FUEL_ECONOMY), 22 (HDOP), 23 (VDOP)
