I’m posting here because I’ve spent a lot of time troubleshooting this issue and I still have not received a response from Yarbo support.
At this point, I’m hoping someone in the community has seen this exact problem and can tell me what actually fixed it.
My Yarbo works normally when I’m close enough for Bluetooth. I can connect to it, control it, and start a mowing job.
Once the rover leaves Bluetooth range, the rover itself keeps mowing normally, but the app loses connection and will not reconnect remotely.
The problem is very repeatable.
Bluetooth ON
App connects normally
Heartbeat = Strong
MQTT Server = Strong
Rover Wi-Fi shows connected
HaLow shows connected
Rover responds normally
Bluetooth OFF / rover leaves Bluetooth range
App goes Offline
Heartbeat changes to Disconnected
The HaLow icon appears in the app but stays gray
Rover appears to lose the remote/Wi-Fi connection
App will not reconnect through HaLow, Wi-Fi, or cellular
The rover itself continues mowing normally
That last part is important.
The rover continues doing the mowing job after the app loses connection, so the mowing/navigation side seems to be working correctly. The problem appears to be specifically with the remote communications path back to the app once Bluetooth is no longer available.
My current software/firmware versions are:
App: V3.19.6 — Latest
Rover firmware: V3.14.20 — Latest
Data Center firmware: V1.1.11 — Latest
One very important point:
This problem did NOT start with firmware 3.14.20.
I had the exact same Bluetooth-only / remote connection problem while the rover was still on firmware 3.14.11.
I updated the rover from 3.14.11 to 3.14.20 hoping the firmware update would fix it.
It did not.
The behavior stayed exactly the same before and after the firmware upgrade.
My diagnostics have shown:
HaLow connection = true
HaLow signal generally around -38 to -60 dBm
Data Center status = RunningNormal
Data Center connection has shown 2 and 3
RTK has shown Status 4
Good satellite count
Cellular has shown Status 1
Rover Wi-Fi shows connected
Bluetooth works normally
I have already tried all of the following:
Completely uninstalled and reinstalled the Yarbo app
Restarted my phone after uninstalling the app
Logged back into the same account
Tested multiple Wi-Fi SSIDs
Tested with rover cellular on and off
Tested different combinations of phone Wi-Fi, cellular and Bluetooth
Power-cycled the rover
Disconnected the rover battery
Power-cycled the Data Center
Updated rover firmware from 3.14.11 to 3.14.20
Verified the problem existed on both firmware versions
Verified the Data Center is running V1.1.11 — Latest
Verified the app and rover both show Latest
Found and tightened a loose antenna connection on the rover
Drove the rover approximately 100 feet away as a test
Verified the rover continues mowing after Bluetooth drops
My Data Center is mounted approximately 25 feet in the air on my barn, although I can easily disconnect and restore its power from inside the barn.
I do not want to start randomly factory-resetting equipment, unbinding the rover, reinstalling the Data Center, or doing anything that could cause me to lose my existing maps unless there is a very good reason to do it.
And this is where my frustration with Yarbo support comes in.
I have already contacted Yarbo support and I am still waiting for a response.
I have provided detailed troubleshooting information, screenshots, firmware versions, Data Center information, HaLow readings, and a very repeatable description of the problem.
I’m not asking them to diagnose some vague intermittent issue.
The symptom is very simple:
Bluetooth ON = connected
Bluetooth OFF = rover goes Offline in the app and remote connection fails
Meanwhile, the rover keeps mowing.
At this point I really need someone from Yarbo to review the backend logs, rover network logs, Data Center communication, cloud session, MQTT/session handling, and account/device binding instead of sending me back through basic Wi-Fi troubleshooting I have already done.
I’m also a 100% disabled veteran, and I am physically unable to mow my property myself.
That is one of the main reasons I bought Yarbo.
For me, this machine is not just a cool gadget or convenience. I actually depend on it to maintain my property.
When the rover disappears from the app every time it leaves Bluetooth range, I lose the ability to monitor it or control it remotely while it is operating around the property.
That makes getting this resolved pretty important.
So I’m asking the community:
Has anyone had this exact problem and actually fixed it?
I’m especially interested in whether your issue turned out to be:
A bad Data Center
A rover communications/network controller problem
A cloud/account session issue
MQTT/backend authentication problem
HaLow handoff problem
Wi-Fi/network service issue inside the rover
Some hidden backend firmware update
Something completely different
If you had the same situation where the rover would mow normally after leaving Bluetooth range but the app could no longer connect to it, please let me know what finally fixed it.
And if anyone from Yarbo sees this, I would really appreciate someone responding to my support case and reviewing the actual logs.
I have already done a considerable amount of troubleshooting.
I just need help getting the remote connection working again.
Thanks,
Tim
