Information about HCI, GAP and GATT for STM32WB15

FSARR.1 · ‎2022-06-24

Hi community.

I try to learn about Bluetooth communication with STM32WB15 but it doesn't have AT server firmware so I try to design my own firmware base on STM32L412 UART communication and STM32WB15 with transparent mode firmware.

The problem is to learn about HCI, GAP, GATT commands because I don't know what is the process to bonder a slave, how to send information by them (commands) among others.

Is there any diagram about the sequence of communication?or any information related to that can help me because I base on AN5270.

Hi @FSARR.1 ,

More details on the HCI, GAP and the GATT commands are available in this Application Note (AN5289) and in this Programming Manual (PM0271).

Also I advise you to follow this link to know how the firmware upgrade services work.

Hi @KDJEM.1, Thanks for answer, Is the other way to road. For now, we found the AT+SERVER firmware application for P-NUCLEO55 (MB1355C-02), I think we can migrate the code for STM32WB15 but the firmware not work good. For example, I can create the server but when I try to connnect my smartphone to this server, P-NUCLEO55 is freeze...

BTW, I was change the stack because all of them working different... now, I try to work with light_stack from 1.13 version.

someone have the same problem with this firmware?
