Hi, I transplanted qn9080-001-m17 to another board, but this board has no buttons to set Bluetooth advertising. Which part of the program should I modify so that it can always be in the advertising state without buttons? Thank you!

hi, I tried it ,but it didnt work. I think you might have misunderstood me. In the picture, SW2 is used to switch between ''GAP Central'' and ''GAP Peripheral'' modes, and SW1 is used to confirm the mode you switch. How to select the gap peripheral mode automatically and confirm it automatically without using the key. Achieve continuous Advertising.

Hi,

Use a timer to configure the mcu role.  At first , the mcu configure as CENTRAL(Use BleApp_Advertise to start advertise). After , such as, 2 s, you change it to PERIPHERAL(Use App_StartScanning to start scan).  Cross run the role. If one role is connected, you can stop that timer until the connection is lost. Before you start advertising, you should stop scanning. The scan too. This is a complex program. 

Have a great day,
TIC

thank you. I've solved the broadcast problem. But I have a new problem. When I use the IAR software, it can connect with my mobile phone, but if I leave the IAR software and only supply power to it, it can't run on its own. What code should I add? When the chip is powered, the program will run automatically.

Hi,

I guess the current is not enough. You may measure the working current in IAR and battery to see if it has difference.

Have a great day,

Thank you. My main problem has been basically solved. I want to trouble you with some small problems. ''Tera Term'' successfully connected with 001-m17, but when I used ''Tera Term'' to display the data I sent, nothing happened. I am sure that the mobile phone has established a connection with 001-m17 and read its service.

Hi,

Do you confirm if the mcu get the data?  Could your board send message to phone? 

Have a great day,
