Hi, I am working on a project that involves, among other things, BLE communication. The host side of the BLE runs on an STM32F091RC, and for the controller, I am using the BLUENRG-M2SP. As a starting point, I used a Nucleo board with the X-Nucleo shield and flashed a zephyr BLE peripheral example on the STM32. The application starts correctly, the initialization passes, and it begins advertising.
The first problem I encountered is when I try to connect a phone. Among other logs, I am getting the following:
[00:01:31.465,000] <wrn> bt_hci_core: opcode 0x2016 status 0x3a
[00:01:31.465,000] <err> bt_hci_core: Failed read remote features (-16)
Besides this log, I am able to connect to the phone, read characteristics, etc. However, what is strange is that when I read the connection destination address, I am getting FF:FF:FF:FF:FF:FF. Also, bonding fails, which is necessary for my project. I have done a lot of investigation on the host app to find what might be missing, but nothing caught my attention. I checked the SPI communication with a logic analyzer, but there is nothing suspicious there, except that the destination address transmitted from the controller is 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF. Do you have any idea what I might be missing? By the way, I ran the same example with the nRF controller connected via UART without any problems.
My zephyr app configuration:
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=2048
CONFIG_BT=y
CONFIG_LOG=y
CONFIG_BT_SMP=y
CONFIG_BT_SIGNING=y
CONFIG_BT_PERIPHERAL=y
