If we received response in two chunks and the first one completes the
command (result=OK or FAIL), and the second chunk pre-empts command processing,
then we performed processing again rewritting the result back to
TIMEOUT. This would invalidate the command, but also causes an
exception: ESP_MODEM_THROW_IF_ERROR(ESP_ERR_INVALID_STATE)
Fixed by checking if the processing already finished in process_line().
Closes https://github.com/espressif/esp-protocols/issues/426
Reusable component in modem_tcp_client example implements a simple
mbedtls wrapper. This update add support for mbedtls deinit() and for
saving and restoring TLS session.
1.0.4
Bug Fixes
- Added USB runner with ESP32S2 with A7670 (edeb936)
- Extend docs on AT client example (1f2ceed)
- Fix pytest exclusion, gitignore, and changelog checks (2696221)
- Fix DTE to post fragments to parsers for USB term (1db1e15)
- Fix DUAL_MODE regression from cb6e03ac (2aada0f)
- Fix AT client example to use custom AT processing (1a5ba98, #352)
In the recent DTE refactoring (cb6e03ac) we install terminal callbacks
in the constructor, but the change missed initializing modem_state
in DTE constructors which take two terminals as arguments to work in
DUAL mode.
1.0.2
Features
- Add factory method for simple creation of custom DCEs (4cf9e50)
- Support custom transport in AT TCP client example (ae629ed)
Bug Fixes
- Fix host test race with async read and d'structor (c89d42f)
- More error handling in cmux protocol (8edbac6)
- Fix netif to set PPP config in C++ way (5287432)
- Fix vfs terminal not to reset read_cb() automatically (25a35e2)
- Fix netif data race causing PPP startup delays (c8c0507, #308)
- Added support for inflatable buffer (cb6e03a, #272)
- Fix LoadProhibited after failed CMUX initialization (IDFGH-10845) (60c87dd)
Loopback terminal uses std::async to inject test data to the test
terminal. There was a hazardeous condition when destructing the terminal
while async batch_read() was in progress. Adding a signal and waiting
for destruction solves the issue.
This change is needed for the fs terminal to work correctly again, after
merging 44bae24c78 which shifted
responsibility of thread safety from a terminal to the DTE. (Before it
was the terminal, which removed this callback safely when processing completed,
and thus we had to check the callback return value). Not the DTE layers
are responsible for thread safety and the return value indicates
success/failure from processing.
Also uses the default clock, the same way as UART terminal.
This allows calling directly:
auto dce = dce_factory::Factory::create_unique_dce_from<SIM7600>(&dce_config, uart_dte, esp_netif);
instead of:
auto dce = create_SIM7600_dce(&dce_config, uart_dte, esp_netif);
Which is very useful when adding a custom module, so we won't need to
update factory layers and add the new device to enums, etc.
To add a new module, you just:
1) Define the module class NewModule: public GenericModule { };
2) Implement the specific commands:
command_result do_work_new_module(CommandableIf *t, params) {}
3) Connect 1) and 2)
command_result NewModule::do_work_new_module(params...)
{
return dce_commands::do_work_new_module(dte.get(), params...);
}
