Troubleshooting OneControl App Not Recognizing More Than One Phone for Curt Echo Controller

Updated 03/19/2025 | Published 03/13/2025

Question:

One control app has officially broken existing Echo devices. At least on iPhones, since there is no way to clear the memory cache for the app there is no way to add a “new” device.

Hey Peter, thanks for reaching out about your Curt Echo # C51180 brake controller!

I'm sorry to hear you're having issues, but I reached out to my contact at Curt and got the following response so I'm posting it here for you to check out the steps:

Remove Bluetooth Profile & Previous app
- Delete the Echo Smart app from your phone
- Navigate to Settings > Connected Devices > Bluetooth and if your Echo shows as saved, select the settings wheel/"i" next to the connection, then Forget/Delete Connection.
- If the Echo is paired in Bluetooth settings it will not allow a connection in the app.

Power Cycle Echo & Start Pairing
- Disconnect Echo from both the tow vehicle and trailer
- While Echo is disconnected, open up the One Control Auto app and allow the permissions that pop up.
- Prior to starting pairing, be sure to have your PIN ready; PIN is located on the reference card that came with your Echo & there is a backup label on the under-side of the door flap on the trailer side of the Echo. It should be 6 digits.
- Once you have everything ready, insert the Echo into the 7-way without the trailer connected (sometimes this method won't work and you will need to plug in the trailer)
- The LED of the Echo should be blinking blue, indicating it is in pairing mode. If it is solid, this indicates it is still paired and you will not be able to pair it within the app.
- With the LED Blinking Blue, select Pair Device.
- On the Devices Found page select your Echo and hit connect
- At this time a window should pop up asking for the PIN - you will have 10 seconds to enter it.

If the customer still has issues with connecting, have them select the Settings wheel in the app > select E-mail Logs. In the body of the email have them put in the case number 5707593 and we can have our development team take a look.

Hi, thank you for the effort. I will follow this procedure and report back. I’ve definitely done this but will give it another try. It’s the cache memory in the app that is the issue, it remembers your echo profiles which is where the fault arises.
