BLE stack 1.3.2 ?

Other Parts Discussed in Thread: CC2540

When I clicked the link for BLE stack release download, I only saw "1.3.2" but this is not announced in the forum yet.

I integrated it with the code base for CC2540 currently working on BLE stack 1.3 and gave it a try, but I found that the connection is terminated due to "connection timeout" as soon as the host (iPhone 5) sends out CONNECTION_PARAMETER_UPDATE in response to connection parameter update request sent by CC2540 (for sure the host sends out RSP to this request first, then sends out the update command). The same code was working ok with BLE 1.3 on the same hardware unit.

What am I doing wrong to get this result? Are there more changes required for 1.3.2 not documented in release note (I've read it through but no clue)?

    Hello -

    I am sorry that you are having trouble with the merge, but thanks to this post, I learned about the 1.3.2 "sneak" release. I loosely monitor this forum and have even 'subscribed' for notifications of new BLE stack releases via the subscribe link at the download site, but no notice until this post.

    Anyway, we run a proprietary iOS App and use a proprietary 128-bit UUID Profile and request automatic parameter update to the mins specified by Apple and so far on iOS 6.1.3 everything looks to be working fine - there was no 'merge' work, just drop the proprietary app into the new install and compile and run.

    Thanks for the reply. It seems to be my problem in porting, and when I re-did everything once again, it works as expected, no disconnection issue found so far.

    Testbed: iPhone 5, iOS7 beta 3, BLE stack 1.3.2, CC2540
