Implementing CB610L radio modem support
|
|
- function getRegistrationCommands() implemented as
pure virtual and overrided for every base radio model
- minor indentation fixes
- function getSimStatusSummary(Json::Value& jData) changed to process
radio modems that do not have separate commands for the SIM presence check
- function getManufacturer(std::string& sManufacturer) changed: AT command changet to 'AT+CGMI'
- src/MTS_IO_QuectelRadio.cpp -- comments correction
|
|
Define the set of debugging AT commands and a function to execute such
commands. The function executes the commands one-by-one end returns raw command
outputs. To be used by radio-query --diagnostics.

behavior when provider is Verizon
Implement getting the CGDCONT from the modem
Implement setting the CGDCONT to the modem

setRxDiversity command moved to common class for Quectel radios - QuectelRadio.cpp.
Add LNA7D radio support.
LNA7D radio supports only 3g and 4g network modes.
Add new command for enabling/disabling diversity. Retained backward compatibility with the old diversity command.

network. GP-1364
Add 2 functions for Telit and Quectel modems:
- disableVoiceSupport: disable voice support (IMS and CSFB) and enable SMS only registration flag.
- getVoiceSupport: get voice support configuration for the current radio.

Switched to the separate fields for SIM MCC and SIM MNC
after a code review.
|
|
Extended the implementation of "getSimCarrierCode" to detect the carrier
(home network) based on the MCC/MNC combination.
Historically mPower used ICCIDs to detect the carrier and apply the
carrier-specific settings. ICCIDs are known for Verizon and AT&T, but
the list of known ICCIDs is not exhaustive.
This change allows the firmware to detect more AT&T SIM cards by using
the MCC/MNC combinations (PLMN IDs) when ICCID is not recognized.
Limitation: The SIM shall be relatively new and report its MNC length,
otherwise MCC/MNC can't be determined and so the carrier code.
|
|
Added an ability to read the PLMN ID (MCC/MNC combination) of the home
carrier from the SIM.
SIM PLMN ID is a part of the IMSI that contains identifier of the home
network. PLMN ID in turn consists of 3-digit MCC (country code) and
2-or-3-digit MNC (network code). The length of the MNC is stored in the
SIM Elementary File called "Administrative Data" (EFad for short).
The purpose of the new functions is to extract PLMN ID from the SIM
if this information is available.

Adding an ability to set UE mode of operation to libmts-io.
There was added two clear virtual methods in iCellularRadio,
correct implementation for them for Telit LTE modems and implementation
with error messages for all other.

Small improvements in code comments.

During testing I discrovered that EG25-G radio may lose some data during transmission
over Serial AT interface or just freezes and stops responding over Serial AT interface.
When ACK mode is not used, the radio may either return an error:
```
Expected: [+QFUPL: 24312545,fa6b], Actual: [+QFUPL: 17124608,b907
+CME ERROR: 409 // Fail to write the file
]
```
Or it may just freeze on modem_at1 interface and stop responding to AT commands:
```
8:0:34:32|TRACE|RADIO| Sending command [AT]
8:0:34:133|DEBUG|RESULT:
8:0:34:133|DEBUG|Shutting Down
```
This commit implements an alternative, ACK mode for data transmission to prevent data losses.
Data is sent in chunks and the device waits for ACK string from the radio for each chunk.
|
|
Added waitResponse overloads to the public interface of ICellularRadio.
|
|
Refactored MTS::IO::ICellularRadio::sendCommand. Moved response waiting code to the
MTS::IO::ICellularRadio::waitResponse function.
**Motivation**
In many places in the modern libmts-io implementation there are cases when we need to
wait for some response from the radio without executing or sending any commands.
Such places may wait for some URC messages, acknowledge strings during
data transmission and so on.
One way to handle such cases is to use `sendCommand` with `cmd` argument set to an empty
string. It generally works but according to POSIX:
"If count is zero and fd refers to a file other than a regular file, the results are
not specified."
The other way to handle such cases is to use `isNeedMoreData` callback of `sendCommand`
function to analyze all the data on the fly. But this approach may not work for data
transfers when `sendCommand` and its std::string argument may not be used to store binary
data with null characters within.
This commit moves the "wait for the radio to answer" part to the separate function
which allows reusablity of such a code.

During testing with L4G1 device I discovered some inconsistencies in behaviour between
EG25-G device and EG95 devices (EG95-NA and EG95-E).
EG25-G device that I have on hands does not allow to perform downgrades using delta images.
When there is an attempt to apply a downgrade delta image it behaves as the following:
- radio prints `OK`
- radio prints `+QIND: "FOTA",502`
- radio is not rebooted
While EG95 radios always reboot at least once to apply the firmware image. Even if it is not valid.
Also I noticed that detach from the serial bus may take more than 10 seconds in some rare cases.
Thus we need to wait not a fixed amount of time but until the radio actually detaches from the bus.
This commit attempts to address the findings described above.

Added more strict handling for comma-separated data in URC messages to prevent out-of-bounds reads.
|
|
Changes after code review:
1. Handle cases when the number of bytes written is different from the number of bytes requested to transfer.
2. Use fstat instead of lseek to determine the firmware size.
3. Renamed TelitRadio::startWrite and TelitRadio::abortWrite functions to better represent their applicability scope.

Implemented firmware version check detection.
|
|
Simplified usage of step callbacks in the QuectelRadio class.
Refactored existing function to use a wrapper and preven repetitive checks.
|
|
Started code cleanup before finishing the procedure.
Renamed functions related to the delta radio firmware upgrade to follow
established patterns:
- uploadDeltaFirmwareFile -> fumoLocalInject
- applyDeltaFirmwareFile -> fumoLocalApply
- removeDeltaFirmwareFile -> fumoLocalCleanup
- new function: updateFumoLocal - encapsulates all the magic for radios
that may not support separate stages for the delta upload and delta apply
|
|
Initial implementation of the "Apply delta firmware" step. Requires cleanup.
|
|
|
|
|
|
Merged all the changes from the intermediate release to master.
|
|
Changes after a code review:
- renamed "MTS Carrier Code" to the "Carrier Code";
- fixed descriptions for the new field and methods.
|
|
This commit adds implementation of the SIM-based carrier detection.
The goal for this implementation is to replace various places in the firmware
that previously relied on the ICCID-based carrier detection, provide some layer
of abstraction and forward compatibility for such places.
It is particularly useful for fwSwitch radios with AUTO firmware selection capability.
