Hello all!
I've been programming for many many years but this is the first time using B4A or any of the Anywhere Software's products. I have a couple of questions I am hoping to get some clarity on:
I have started off using the BLEExample that works, connecting to my Bluetooth LE module. However, I need to add the capability of sending a message, in text, to the device.
1 - Looking over and working with this sample, and a few others on BLE, I cannot find out where to get the documentation on the BLE2 library so I cannot seem to figure out what functions are there, and how to use them properly. This is specific, but the same question really applies to all libraries.
2 - Is there a resource that has all of the functions etc in one place that can be reviewed? Please see below.
3 - What I *think* I need to do is to just add a field for entering the text to send, and a button to send it. That part was easy. But the *complicated* part is "how" to send it and in what form?
I have this code, but I get an error on compiling-
Error description: Cannot cast type: {Type=String,Rank=0, RemoteObject=True} to: {Type=Byte,Rank=1, RemoteObject=True}
Error occurred on line: 215
manager.WriteData(ConnectedName,charId, msg)
Word: msg
OK, so how to correct? It looks like it wants msg to be in byte format, how to convert? Is there a resource that has all of the functions etc in one place that can be reviewed?
Finally, any other tutorials or sample code to help get me going would be really appreciated. BTW, I did watch most of the videos - they have been helpful.
Thank you,
Tim
