Firmware update instructions.

Please note that updated config apps for iOS and Android are required to enable 9600 baud. On iOS, you must be using the Mobilinkd Config app version 1.1 or greater. On Android, the Mobilinkd Config app version 1.3.0 or greater is required.

2.0.1: Fix corrupted TX when connected via USB. Reduce minimum frame size.

2.0.0: Add 9600 baud support.

1.1.7: Eliminate Bluetooth data stalls.

1.1.6: Avoid deadlock on startup.

1.1.5: Initialize PTT & KISS parameters properly when running without a battery.

1.1.4: Do not detect carrier when no signal is present. This allows the TNC to work with a closed squelch.

1.1.3: Fix USB serial port behavior on Windows impacting Winlink Express. Improve 1200 baud decode performance. Change modulator to send HDLC idle frame during preamble (TX delay).

1.1.2: Fix corrupted packets caused by SLIP encoding error. Reduce packet collisions by fixing CSMA handling defect.

1.1.1: Fix issue where short 17-byte packets were being dropped. This defect impacted Winlink users.

1.1.0: This decreases the latency over BLE connections. It noticeably improves responsiveness of the iOS Config App. (This update does little if you are not on iOS.)

  1. Could you give some directions on how to install ver 3.49 of the firmware? Thanks.

    • The easiest is to use the firmware upload feature in the Android configuration app. Install the Mobilinkd app from Google Play. Make sure the TNC is paired to the Android device. Then just download the firmware file from this site using your Android device. The app will detect the firmware and walk you through the firmware upload process.
