Hello,
I am working on a project for nRF9160 that is supposed to provide FOTA/DFU functionality for main application, modem and nRF52832 co-processor acting as SPI HCI slave. For sake of MCUMGR interface I am using 2 pin UART interface (RX/TX) and SMP server running on nRF52832. So far I have confirmed that SMP server is running correctly on nRF52 and I am able to update it using CLI MCUMGR from my linux development machine.
However, MCUMGR client on nRF91 side doesn't seem to work if I set CONFIG_ZCBOR_CANONICAL (which is required by CONFIG_LWM2M_RW_SENML_CBOR_SUPPORT).
By enabling CONFIG_ZCBOR_VERBOSE I am able to catch following output when running mcumgr read command:
rtt:~$ mcumgr read New backup (level 0) rem: 506, cur: 0xa1, ec: 0x0, err: 0, value_encode_len Process backup (level 0, flags 0x3) list_count: 0 rem: 506, cur: 0xa0, ec: 0x0, err: 0, value_encode_len zcbor_map_start_decode rem: 244, cur: 0xbf, ec: 0x1, err: 0, value_extract ZCBOR_ERR_IF(additional > ZCBOR_VALUE_IS_8_BYTES, 7) ZCBOR_ERR(7) ZCBOR_FAIL rem: 244, cur: 0xbf, ec: 0x1, err: 7, WEST_TOPDIR/modules/lib/zcbor/src/zcbor_decode.c:139 ZCBOR_FAIL rem: 244, cur: 0xbf, ec: 0x1, err: 7, WEST_TOPDIR/modules/lib/zcbor/src/zcbor_decode.c:662
If I switch to CONFIG_LWM2M_RW_SENML_JSON_SUPPORT (which is not desired) I can issue commands but still get some CBOR errors, i.e:
rtt:~$ mcumgr read
