Field Maps 25.2.0 update Creating Issues with Trimble Mobile Manager

[NorthVanForester]

Hello,

Is anyone else experiencing Trimble Mobile Manager issues when trying to connect an external GPS to Field maps? Field Maps 25.2.0 removed all previous connections to external recievers. Connection attempts lead to endless looping from Field Maps to Trimble Mobile Manager.

Field Maps 25.2.0 update has created huge disruptions across our organization.

Another issue: the keyboard does not move out of the way when you're typing. Usually the attribute field auto-scrolls so the keyboard is just below the field in which you are typing.

Hi @NorthVanForester , what devices are you using (phone, trimble receiver models)? Also, what version of Trimble Mobile Manager is install? Ensure you have the latest version of that as well. Thanks!

Hi Colin,

We are using iPad mini 5's or newer with Trimble R2s. We are using TMM 2025.20.221. 

Trimble released a video with a new workflow https://www.youtube.com/watch?v=myTRdNGtG8c

This is the opposite of the old instructions provided by Esri. Documentation on the Esri site seems to now be updated to reflect the change in workflow.

Yes this is the updated workflow for the new version of Field Maps 25.2 as the underlying architecture has changed as it relates to connecting to Trimble receivers. This is why existing Providers needed to be cleared. Are you still having issues with an endless loop when connecting? Have you already tried removing and re-adding in both Field Maps and TMM?

We have had two cases of endless loop bouncing between TMM and Field Maps on iOS. The users weren't able to turn off or hard reset the iPad. They had to wait until the battery died. In one case it had to be taken to IT for a factory reset.

@jmaxwell_braun @NorthVanForester if possible can you both submit this to Esri Tech Support so we can better track the impact. It also will not hurt reaching out to Trimble support. Both are aware of this issue and looking into it. 

[jmaxwell_braun]

@ColinLawrence will do. I didn't submit to Esri tech support because the issue is intermittent and I cannot reproduce reliably.

In one case yesterday the user was able to interrupt the loop by quickly switching to integrated location provider when Field Maps is visible, then restarting the iPad. It was fine after that.
