u-connectXpress v3.0.0 for ANNA-B112
Description
Reference
LE secure connections with security mode 4 incorrectly outputs event +UUBTUPD
and accepts AT+UBTUPE.
NOTE: Event +UUBTUPD is replaced with +UUBTUC. Where both AT+UBTUPE and
AT+UBTUC can be used for acceptance. For more information and example of
configuration see u-connectXpress User Guide [3].
UCS_DEV-676
The command to read multiple GATT characteristics (AT+UBTGRM) is not
functional and returns an error response.
This limitation has been found to be incorrectly reported as a known limitation. The
command is defined only for client.
TE_NINA_NRF_FW-254
UCS_DEV-30
The disconnect command (AT+UDCPC=1) is not functional until reception of the
confirm event of the connect command. The workaround is to wait for the
connection confirmation before sending the disconnect command.
TE_NINA_NRF_FW-284
UCS_DEV-142
2 New features
u-connectXpress v3.0.0 for ANNA-B112 has all the features of previous software releases,
plus improvements and new features such as the main ones described below. For more
information about using these features, see the Using u-connectXpress software UserGuide
[3] and the u-connect AT commands manual [4].
2.1 Multiple central support
Connections from up to 6 centrals (for example mobile phones) can be accepted and handled
simultaneously in peripheral role and up to 4 centrals in combined central/peripheral role. For
more information and example of configuration see u-connectXpress User Guide [3] and the
AT command AT+UBTCFG.
2.2 Connection status information
It is now possible to read out all active connections and detailed information about each
connection, such as connection interval, slave latency, supervision timeout, MTU size, PDU
payload length, role, and more. For further details, see the AT command AT+UBTLELIST and
AT+UBTLESTAT.
2.3 Changeable MAC address
It is now possible to change the factory programmed MAC address to a customer defined one.
For further details, see the AT command AT+UMLA.
2.4 Configurable reconnect timer
It is now possible to configure the reconnect timeout interval for a connection which is using
connection scheme “always connected”. For further details, see the AT command AT+UDDRP
and the new optional parameter <ac-to>.
3 Notes and limitations
3.1 Solved limitations
UBX-20031225 3/4
u-connectXpress v3.0.0 for ANNA-B112
Description
Reference
In EDM mode, when a central node connects to a remote peripheral device, the wrong
frame size is reported in the EDM Connect Event (0x0011). To get the correct size,
use the Resend Connect Events (0x0056) command.
TE_NINA_NRF_FW-531
UCS_DEV-185
The un-bond command (AT+UBTUB) is not functional until reception of the confirm
event of the bonding command. The workaround is to wait for the bonding
confirmation before sending the un-bond command.
TE_NINA_NRF_FW-677
UCS_DEV-77
The response to "Maximum allowed output power" (AT+UBTCFG param_tag 4) is the
unsigned representation of the configured value.
TE_NINA_NRF_FW-748
UCS_DEV-78
When going from Discoverable mode to Not Discoverable (AT+UBTDM), and then
back, the Scan Response data is cleared.
UCS_DEV-176
Extended advertisement (AT+UBTAD) should support up to 252 bytes of data but is
limited to maximum 232 bytes of data.
UCS_DEV-79
The module resets when extended advertisements are disabled after enabling them
(AT+UBTLECFG parameter tag 29).
UCS_DEV-83
The minimum value for the Connect linkloss timeout (AT+UBTLECFG parameter tag
7) is 100 ms, but setting any value <110 makes the module hang on store and
restart.
UCS_DEV-174
It is not possible to switch to EDM after establishing a Bluetooth low energy
connection. No data can be transferred. The workaround is to first switch to EDM,
and then establish the Bluetooth low energy connection.
UCS_DEV-175
Not possible to send notifications longer than 20 bytes when setting MTU size 247
(AT+UBTGSN).
UCS_DEV-227
Description
Reference
When using the external pairing functionality (pairing using SWITCH_0, see
AT+UBTSM), the LED flashes orange (GPIO pins for red and green LEDs are active)
for 60 seconds even after successful bond.
TE_NINA_NRF_FW-426
UCS_DEV-29
The command to discover all characteristic descriptors (AT+UBTGDCD) is missing
the response event when using 128 bit UUIDs.
TE_NINA_NRF_FW-910
Possible SPS data loss when L2CAP fragments are small (3 bytes)
UCS_DEV-909
