Our organization has several hundred TDC650's. For the most part, these work wonderfully for most of the needs. Recently, several devices have been unable to connect to the Integrated Receiver. These are on devices that are stored safely and handled with care. The first indication is that the 3rd party software that utilizes the Trimble Precision SDK states that it cannot reach the antenna. Opening Trimble Mobile Manager with no other apps open, we are unable to get connected to the Antenna. Closing TMM and opening Trimble Installation Manager, the app opens, verifies the version then goes to Connecting to Receiver. At that point, one of several things happens. One, the app may force close, or it may say Failed to detect receiver. In some cases, it states "Fail to Change the baud rate at 11500Bds". This is on previously fully functioning devices with no damage, drops or anything. TIM Version 1.70.136, Receiver when I could see it previously, it was on 4.33. TMM is on version 3.1.2.1407 and it is connected to the integrated receiver.. the device is updated to the September Android Security update. I cannot see any update that comes through that could have caused this. We are using SOTI MDM, but this happens on random devices and doesn't affect others. Essentially the device is rendered useless.  

Hi Matthew

If you have recently updated the GNSS firmware via TIM? 

If so then you'll need to do the following to resolve this

1. Download an app called GNSS Loader via the Play store
   • For TDC650 download the tdc650_ upgrade_v4.33.tar file to the internal storage of the device (default Download
     folder)
   • For SP30 download the sp30_upgrade_v4.33.tar file to the internal storage of the device (default Download folder)
2. Launch GNSS Loader and allow all permissions
3. Select Upgrade Firmware
4. Select the *.tar file you downloaded in step #1
5. After the firmware installs go to the ABOUT menu and check the version is 4.33 
6. Exit the application and retry connecting in TMM ensuring you are not already connected in any other apps

I would also encourage you reach out to your local Trimble reseller who will be able to guide you through this process

I'll check with our reseller. We had ordered from two resellers one in Ohio and one in Texas, but we manage the devices centrally from Ohio to 10 other States. The devices are locked down so that users cannot easily access the settings. I physically have a device with me in this case, and the instructions provided have not worked. Sits at File Copy in progress with no progress. Going to let it sit for an hour or two, but I wouldn't think that should be needed by the size of this file. The firmware in GNSS loader already shows it is on 4.33 which may be why there is no progress? I guess I am confused now on why use GNSS loader vs Trimble Installation Manager. Do we even need TIM installed on the devices? Is GNSS Loader more stable in installing the updates to the receiver? GNSS Loader seems to be able to maintain the Precision options, RTX Subscription and the Firmware update. We generally do not use the device with a Trimble created controller and only use TIM to maintain the licenses and Firmware on the integrated Receiver.
