Firmware 7.53.1.A1 Release Notes

Feature	Description
[eUICC] Local ERA-GLONASS subscription switching mechanism.	For ERA-GLONASS project, multiple subscriptions can be provisioned in the embedded UICC. One of them is dedicated to ERA-GLONASS emergency call. The purpose of this new feature is to provide an interface triggering the swap to this ERA-GLONASS subscription for eUICC cards from following manufacturers: G&D, Gemalto, Morpho and Oberthur.
[eUICC] Remote SIM provisioning	Support of remote SIM provisioning as defined by the GSMA standard
[eUICC] Remote SIM subscription swap.	Support of SIM refresh procedure used by the network server for swapping the SIM subscription.
Bearer Independent Protocol (BIP) support	The Bearer Independent Protocol, as defined in 3GPP specifications, provides to the UICC a standardized way to use AirPrime Packet Data bearer to communicate with remote entities.
SIM245 support	Mandatory device requirements support as defined in DENATRAN SIM-245 specification.
OFF Mode management	Support of OFF Mode procedure from legacy Open-AT products in addition to the current AirPrime SL808xT OFF mode procedure. +WHCNF AT command allows selection of the method. +CPOF triggers the OFF mode.
Disable Automatic Power transition	The Automatic Power transition protects the AirPrime module against destructive temperature by setting it in low power mode when temperature exceeds a threshold. In some critical situations, like Emergency Call, this feature may be disabling. This feature provides then an interface for disabling the Automatic Power transition.
USB CDC-EEM class support	Standard CDC-EEM interface support.
USB enumeration customization	Change the default AirPrime SL808xT USB composite enumeration by a single CDC-EEM interface enumeration.
USB configuration with event management	Open-AT application can be notified when USB connection or disconnection event occurs.
8-wire UART support	Support of a full 8-wire UART interface in addition to existing 4-wire UART interface. UART configuration may be changed dynamically through AT command.
WAKE_N signal support in addition to 4-wire UART.	When 4-wire UART interface is used, WAKE_N signal can be enable to wake-up an host microcontroller when selected events occurs (set using AT+WRIM command).
ADC interface	Analog to Digital Conversion interface support through AT command.
I2C interface	I2C interface support from Open AT Bus Service.
Audio configuration enhancement	Audio Settings have been fine tuned to comply with VDA
Audio Echo cancelation and Noise Suppression algorithms enhancement.	+ECHO command have been enhanced to allow more customization parameters for: Echo cancellation and Noise suppression.
Audio equalizer support	The equalization controls the sound quality
Improved Audio PCM Interfaces	The ADL Audio Service allows handling audio resources, and play or listen supported audio formats on these resources (single/dual tones, DTMF tones, melodies, PCM audio streams, decoded DTMF streams).
Automatic Volume Control	The Automatic Volume Control (AVC) algorithm will react to background noise fluctuations
Automatic Gain Control	The RX Automatic Gain Control (AGC) compensates the variations in audio gains from the landline side. The TX Automatic Gain Control (AGC) compensates the variations in audio gains from the mobile side to allow a constant audio level in the TX direction.
CPU Load indication	Ability to monitor the CPU load.
ADL TCU Accurate Timer	Hardware Timer support
Local Trace Session	Ability to manage trace collection and record them in the file system.
WPOW enhancement	+WPOW command available for W-CDMA frequency bands.
File System provisioning	Ability to ease application and file system provisioning at manufacturing
Reliability	Improve robustness and reliability of the AIrPrime module in case of flash corruption.
Spy mode	When spy mode is configured on the AirPrime module, the AirPrime module will not perform mobility management procedures, including registration on a PLMN. The purpose of this mode is to avoid network congestion due to large volumes of unnecessary network registration, de-registration and location update signaling from AirPrime modules which don’t need to be reachable from the network.
Ecall only mode	The eCall only mode correspond to standard implementation of EN16062 – chapter 7.1.3 and ETSI TS 122　101. eCall only mode is determined by USIM card configuration.
Ecall Flag	When an emergency call is initiated, the application can specify which emergency service is required by settings the eCall flag. This flag makes it possible to differentiate automatically and manually initiated eCalls for instance,
