How would I send 1 byte numbers on thunkable. There’s a function already preset on MIT App Inventor, but I need to replicate it on thunkable. [image] I know that I will use the transmit function block and that I need the UUID. What I don’t know is how to make it send a 1 byte number. It has the da…

If your receiving device expects a byte number then just use the number from the number drawer, if in the other hand, your device expects a byte array then you need to have the number inside a list.

Sorry, I think that I should be using the Transmit Byte Array block and not the Transmit String. Is that what it would look like to send 1 byte to a BLE device? [image]

That looks like it should work fine to me. I don’t think it actually makes any difference whether you use the “string” or “byte-array” blocks - I believe it’s just to improve readability by sign-posting its intended purpose (remember that a string at least in ASCII, is just a byte array). I’ll add t…

Sounds good, thank you. Would you know how to return the value of the value TGTMove just like I did on MIT App Inventor? [image]

See this post which contains all the knowledge I currently have on reading values over BLE using Thunkable. Unfortunately, it is much more limited than MIT AppInventor. You will need to do your own reading/experimenting to determine whether the service you are targeting is READ ONLY or not. If it is…
