Hi,
I'm trying to implement firmware updates over BLE with mcuboot as boot loader.
I got it working with NCS 2.6.1, but I've upgraded to NCS 2.8.0 and now nRF Connect for iOS gives the error: Sending the request timed out.
I have the following configuration (of which I think it's important to the issue):
sysbuild.conf:
SB_CONFIG_BOOTLOADER_MCUBOOT=y
SB_CONFIG_BOOT_SIGNATURE_TYPE_ECDSA_P256=y
SB_CONFIG_BOOT_SIGNATURE_KEY_FILE="${APP_DIR}/priv.pem"
SB_CONFIG_PARTITION_MANAGER=y
SB_CONFIG_DFU_ZIP=y
SB_CONFIG_DFU_ZIP_APP=y
prj.conf:
CONFIG_BT_SMP=y
# FOTA configuration
# Configuration is basically the expansion of:
# CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y
# CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU_SPEEDUP=y
CONFIG_MCUMGR=y
CONFIG_IMG_ERASE_PROGRESSIVELY=y
CONFIG_NET_BUF=y
CONFIG_ZCBOR=y
CONFIG_CRC=y
CONFIG_MCUMGR_TRANSPORT_BT=y
CONFIG_MCUMGR_TRANSPORT_BT_CONN_PARAM_CONTROL=y
CONFIG_MCUMGR_TRANSPORT_BT_PERM_RW_ENCRYPT=y
CONFIG_IMG_MANAGER=y
CONFIG_STREAM_FLASH=y
CONFIG_FLASH_MAP=y
CONFIG_FLASH=y
CONFIG_MCUMGR_GRP_IMG=y
CONFIG_MCUMGR_GRP_OS=y
CONFIG_MCUMGR_GRP_OS_BOOTLOADER_INFO=y
CONFIG_MCUMGR_GRP_OS_MCUMGR_PARAMS=y
CONFIG_MCUMGR_TRANSPORT_BT_REASSEMBLY=y
CONFIG_BT_L2CAP_TX_MTU=498
CONFIG_BT_BUF_ACL_RX_SIZE=502
CONFIG_BT_BUF_ACL_TX_SIZE=251
CONFIG_BT_CTLR_DATA_LENGTH_MAX=251
Apart from shuffling a few config's from prj.conf to sysbuild.conf, the only change is that I needed to add 'CONFIG_MCUMGR_TRANSPORT_BT_PERM_RW_ENCRYPT' to allow access to the SMP characteristics as CONFIG_BT_SMP is enabled but I do not have MITM protection.
I can use nRFConnect for iOS to list the images, get bootloader info and reboot the device, so it seems that the basic SMP commands are working. Why does it error-out while trying to perform the actual update? Did I miss something while migrating to NCS 2.8.0?
Thanks in advance.
Kind regards,
