Reach Firmware 27 Update: Support for SIM Cards with Password Authentication and More

We’ve released a new Reach Firmware 27 update. It’s now available for all devices and brings some valuable features and improved stability.

Support for SIM Cards with Authentication

You can now set up the Mobile data connection using M2M SIM cards that require password authentication.

To configure the connection, enable data roaming on your phone or tablet and go to the Mobile data tab in the ReachView 3 app. Then enter your APN (Access Point Name), choose the authentication type and fill in your password and username.

Improved Compatibility with OPUS, Upgrading via Mobile Data, and 1230 RTCM3 Messages

In the Reach Firmware 27 update, we’ve also implemented several other changes:

  • Improved compatibility with OPUS
    Now you can pick an option This log is for OPUS in the RINEX log settings. Also, the log file names format was changed so that they are supported by OPUS.

  • Unlocked upgrading Reach Firmware via mobile data for Reach RS2
    Select the Allow updates using mobile data toggle in the Mobile data tab. You can still download updates via Wi-Fi if the receiver is connected to a Wi-Fi network.

  • Added 1230 RTCM3 messages for RS2 and M2
    In the Corrections Output tab, you can find 1230 RTCM3 messages, which improve RTK quality with GLONASS enabled.
