Hello,
I'm trying to make the nrf5340-DK capable of connecting to BLE from multiple devices.
The program is based on: Bluetooth: Bluetooth: Peripheral UART.
I found the following discussions on this:
BLE multiple connections support - Nordic Q&A - Nordic DevZone - Nordic DevZone
However the order only let me connect to one device and then it prints an advertising error:
[00:00:42.735,412] <wrn> bt_hci_core: opcode 0x200a status 0x0d [00:00:42.735,443] <err> bt_adv: Failed to start advertiser [00:00:42.735,473] <err> uart_debug: Advertising failed: -12
and thus nrf5340 stops being connectable for other devices.
in /proj.conf I have:
# UART async CONFIG_UART_ASYNC_API=y # Console/logging CONFIG_CONSOLE=y CONFIG_UART_CONSOLE=y CONFIG_LOG=y CONFIG_LOG_BACKEND_UART=y CONFIG_LOG_BACKEND_RTT=n # BLE CONFIG_BT=y CONFIG_BT_PERIPHERAL=y CONFIG_BT_DEVICE_NAME="UART_Debug" CONFIG_BT_MAX_CONN=4 CONFIG_BT_MAX_PAIRED=4 # NUS service CONFIG_BT_NUS=y # BLE settings CONFIG_BT_SETTINGS=y CONFIG_FLASH=y CONFIG_FLASH_PAGE_LAYOUT=y CONFIG_FLASH_MAP=y # DK library pro LEDs CONFIG_DK_LIBRARY=y # Memory CONFIG_HEAP_MEM_POOL_SIZE=4096 CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=2048 # Assert for debug CONFIG_ASSERT=y
in src/sysbuild/ipc_radio/prj.conf I have:
CONFIG_SERIAL=n CONFIG_UART_CONSOLE=n CONFIG_LOG=n
and in src/sysbuild/ipc_radio/prj_bt_rpc.conf:
CONFIG_SERIAL=n CONFIG_UART_CONSOLE=n CONFIG_LOG=n CONFIG_BT_PERIPHERAL=y CONFIG_BT_CENTRAL=n CONFIG_BT_CTLR_SDC_PERIPHERAL_COUNT=4 CONFIG_BT_MAX_CONN=4 CONFIG_BT_MAX_PAIRED=4 CONFIG_BT_DEVICE_NAME="Nordic_UART_Service"
Can you advise me how to ensure multiple connections (from multiple devices) to nRF5340-DK possible at the same time, please?
Thank you
