How To Solve Ble Connecting Cause 133 Statue

We are a company that specializes in IoT devices. Recently, during our repeated connection and network configuration stress tests using BLE, we found that it is prone to returning error code 133 during Bluetooth connections, and this issue can persist for a period of time.

The model of the phone we are using is Galaxy Z Flip3 5G SM-F711U1 / SM-G986U1.

We have confirmed that the IoT devices are functioning normally when this issue occurs because we have successfully connected using other phones at the same time.

We have also found that temporarily resolving this issue is possible by turning off and then turning on the Bluetooth service on the phone.

Currently, we have tried the following:

  1. When this issue occurs, we repeatedly attempt to connect to the device, which provides some relief, but does not completely solve similar problems.

  2. We have found that asking the user to restart Bluetooth can alleviate this issue.

We would like to inquire:

  1. What causes a similar error code 133 to occur?

  2. How can we alleviate similar situations?

My response however is the same.

Samsung’s mobile developers do not follow this board to prevent any potential dispute or misunderstanding as to the similarity between Unsolicited Submissions and our internally and independently developed products, technology and services.

I would suggest you open a Support Request and provide this information there.

I apologize for not being able to report this for you but they will probably want follow-up information.
