i had create a simple app for test to get Bluetooth
now it can connected with my PCB-Board
(standard BAUD-Rate 9600)
my pcb board send array 20 bytes via Bluetooth-LE JDT-23
but it has nothing to display why @_@!
what is mistake..? Thank you
- Make sure both UUIDs are correct.
- Try to pick up anything this way:
- Try to receive the message as text.
The blocks look correct. What is this device? And are you sure it sends correctly?
i think.. i send correctly, before moment it work but i confuse why it not display now
this is logic analyze pin between mcu and BLE-module-JDY-23
UUID How can i check.. it valid or not, i copy UUID from other site ,
but in past this UUID it work now it not work, very confuse @_@!
this problem is solved, i forgot config PWRC to high level, so it not send data via BT O!
