I sent an “AA” via a Bluetooth debugging tool on my phone. How can I receive it in my own application? Also, which API should I use to send messages? I didn’t find it in the documentation. Or are there any other documents? Please send me some.
Do you mean that content could originally be displayed on the LCD screen, but after adding Bluetooth, the LCD screen no longer shows anything? Has the system crashed? Could you please provide more information, such as logs of runtime anomalies, for further analysis?
I want to use LOG_I to print the information received via Bluetooth in my own app. When I connected my phone to the Bluetooth using a Bluetooth debugging tool and sent data, the received data was printed out. The response message I received on my phone is 01000600370002005A00.
The newly added Bluetooth code probably has interfaces not declared in “app_rtm_export” or “lvgl_rtm_export”. Please refer to the section “Component Description → Dynamic Application Guide → 10.6 Unable to Display Issues” for handling: 动态应用指南 - SiFli Solution Documents 文档
All API interfaces used by dynamic applications must be declared in the symbol table.
