Describe the bug
Use the .timeout(5, TimeUnit.SECONDS) operator to disconnect after 5 seconds of successful connection.

To Reproduce
Code to reproduce the behavior:

rxBleDevice
    .establishConnection(autoConnect = false).timeout(5, TimeUnit.SECONDS)
    .doOnError { Log.e("establishConnection", it.stackTraceToString()) }

Expected behavior
Attempt to establish a connection for 5 seconds. If the establishment is successful, no TimeoutException is thrown. If the establishment fails, a TimeoutException is thrown.

Smartphone (please complete the following information):

  • Device: Sony Xperia III
  • OS: Android 12
  • Library version: com.polidea.rxandroidble2:rxandroidble:1.12.1

Logs from the application when bug occurs (this will greatly help in quick understanding the problem)

establishConnection: java.util.concurrent.TimeoutException: The source did not signal an event for 5 seconds and has been terminated.

Hello!

Thank you for using the library.

This is a general usage question and as such should be posted on stackoverflow with rxandroidble tag—it will be easier to find by other users. Also feel free to check already posted questions as a similar one may be already answered.

What you experience is expected behaviour of RxJava API operator .timeout(int, TimeUnit). To achieve what you want you should use a different one or an assembly of several operators.

Best Regards

I have encountered the same problem. How can I solve the problem of modifying DeviceModule connect timeout DEFAULT-CONNECT-TIMEOUT=35 default value
