Connection 'flaps' when Bean goes out of range and comes back into range #3

I have found that if a Bean goes out of range while connected to a device and the device re-initiates a connection then when the device comes back into range, the connection will 'flap'. The bean disconnects with the didDisconnectBean: delegate method reporting -

Error: Error Domain=PTDBean Code=100 "Validation Failed. Retry count exceeded" UserInfo=0x17806bbc0 {NSLocalizedDescription=Validation Failed. Retry count exceeded} { NSLocalizedDescription = "Validation Failed. Retry count exceeded"; }

The bean then reconnects before disconnecting a short time later with the same message.

Increasing PROFILE_VALIDATION_RETRY_TIMEOUT to 100.0f in PTDBean.m seems to resolve the issue

Hi Paul, thank you for the info. I'll look into the problem and have a fix shortly!

Hi @paulw11 , I'm looking into this issue currently and having difficulty recreating or understanding the problem. Can you please explain what you mean by flapping?

Is the bean repeatedly connecting/disconnection indefinitely?
Can you please share your code (or some of it) where you are implementing your PTDBeanManager delegate. Are you attempting to reconnect upon disconnection?

thank you
-Ray

Hi,

Yes, I am auto reconnecting

The code is available here - https://github.com/paulw11/BeanLock

I have included part of the debug log below. The log starts from about the
time I took the Bean out of range. You can see it disconnects, and then
when I bring it back into range I get repeated connection problems that
seem to be caused by the validation process timing out and resetting the
connection. I found that if I increased the time allowed for validation
then the problem goes away.

Hi, what's the status with this issue now? I have the exact same problem, setting PROFILE_VALIDATION_RETRY_TIMEOUT higher made a big difference (very glad i found this thread - thanks paul!), but it still happens occasionally

@peterworth, we are in the process of reworking the connection process. So this issue will soon be resolved in the next major release.

For now, does it help if you set PROFILE_VALIDATION_RETRIES to be 1 ?
