Hi everyone,

I ask a question about an issue at this link but a I 'close the question' too quickly.

With what suggested ( and how is in the attachments ) I modified the code but the problem is still in the BT.Connect block.

BT.Connect is blocking, right? How can I avoid to wait until my app go freeze?

Hi cappe

Nice try but you haven't done what was suggested. The Clock Timer should be Sending the data one-at-a-time to each device in the List. 

I will put together an example for you.

Hi again cappe

Next time you need to post an image of your Blocks, do this (for an image we can actually read!)    How to create an image of your Blocks and add it to your Forum Post

This is how a Timer can send data to multiple devices, one-at-a-time:


Note, code is not tested here but should work(!). Test as an APK on your Android Device.
