Hey @huang7017t

can you try using your own string in the blocks here, rather than the string coming from the Text_Input , just to see whether or not that makes a difference?

Thanks!

The same error occurs in the use string

Can you write to it from another device?

Or from your Serial prompt?

:unable
Or from your Serial prompt?
:BLE Scanner can prove that the HM10 is operating normally, and can output and read

Sorry, my English is not that good
I’m afraid that some behaviors that would be impolite through GOOGLE translation

It still doesn’t work, I’m afraid. Do you have BLE transmit function anywhere in the timeline to be fixed? Has anybody ever confirmed that it works?

The same problem with IOS. No solution still.

The same problem

SAME PROBLEM!!! no solution yet…
