Android Question BLE2 Communications Implementation

[Denny Hopp]

The BLE2 library is working great for me and I am able to read and write characteristics to/from my custom target. I have a timer running that performs a characteristics read every 2 seconds. However, if I perform a write at the same time a read is occurring, the App crashes. How can I tell if a read is occurring so that I can wait to perform a write? Thanks!

Also, I am using the following instructions to turn on the notify characteristic:

Public Sub startSwitchNotify
manager.SetNotify ("feedbeef-face-deaf-fade-beadbeadaced", "a1b2c3d4-e5f6-a1b2-c3d4-e5f6a1b2c3d4",True)
Log("Set Notify")
End Sub

Whenever this sub is called, the program crashes. Any ideas?

Can you post the error message from the logs?

Hi Erel. I figured out what was happening. I was not connected and tried to enable the notify characteristic. The notify is working great now! The only issue I am having is the app crashing when I try to Write to a characteristic while a characteristic Read is occurring. Is this a normal occurrence?

 

[Erel]

Currently the library doesn't synchronize writes and reads. So you need to do it yourself. I do however plan to fix it. Which error do you get?

 

[Denny Hopp]

Here is the error log. The error is flagged at the line that calls the characteristic write.
