Why the bluetooth serial port module, on the computer, mobile phone and computers to send and receive information from each other, but check the stm32f103zet6, but can only send not receive messages from the phone

CodePudding user response:

The reason why you single-chip computer configuration

CodePudding user response:

refer to 1st floor coating response:

why you MCU configuration

A serial port configuration is no problem, I use with computer serial assistants will be able to send, to the mobile phone bluetooth, MCU can't accept

CodePudding user response:

Mobile phone to accept and send?

CodePudding user response:

The

quoted Chen _ hehe reply: 3/f

the same and send mobile phones to accept?

Does not agree, it is only by single-chip computer sending mobile phone can receive, send single-chip computer and mobile phone, microcomputer but could not return to the (or received)

CodePudding user response:

If the configuration no problem, make sure MCU have received serial data (without interruption without DMA),
If I use interrupts, add a breakpoint in the interrupt program register contents,
