Note that documentation for random_max_start_delay config setting has
been changed to indicate that the setting is in seconds, and always has
been. No functional change.
Major changes:
- Dependency to FileHandle removed from base classes
- AT_CellularDevice owns the default FileHandle and shares it with AT -classes
- Hang-up -detection moved as CellularContext::configure_hup(). Cannot be configured via CellularDevice any more.
Result on NRF52840_DK + BG96:
GCC:
Total Static RAM memory (data + bss): 29360(+296) bytes
Total Flash memory (text + data): 130660(-832) bytes
ARM:
Total Static RAM memory (data + bss): 261554(+8) bytes
Total Flash memory (text + data): 127573(-1193) bytes
IAR:
Total Static RAM memory (data + bss): 25479(+296) bytes
Total Flash memory (text + data): 102418(-527) bytes
RAM increase is because now ATHandler is no longer created with new -operator but is now member of AT_CellularDevice,
so image tool is able to count it. Actually total RAM consumption has decreased due to removed variables.
ATHandler is part of our API so header file was moved under API folder and .cpp file was moved under device/ folder
ATHandler is used in both AT and PPP mode so it has been in slightly wrong place at the beginning.
Add a missing license header.
Remove semaphores and add +CRTDCP to support async operation.
Fix delete context and disconnect to execute just once.
Add support for NONIP PPD type.
Change CellularNetwork::clear() to virtual so it can be overridden.
Add missing license headers.
Remove semaphores to allow async operation.
Change hex format to allow binary payload.
Limit payload size to 100 bytes.
Fix missing plus char at +QCFGEXT.
- Earlier some variables were public even though used only internally
- Also refactored variables to the end of class definitions
- Removed duplicate _property_array from CellularDevice
- Changed _impl methods as protected
When AT traces are enabled and very long AT commands are traced,
system can easily go to unwanted state. Therefore the length of the AT
traces is limited to DEBUG_MAXLEN (currently 60 characters).
This commit fixes read_hex_string, read_bytes and write to use this
limitter.
According to [3GPP-TS_24.008] the maximum size for Non-IP link MTU is 1358 octets to prevent fragmentation in the backbone network.
Therefore reduced the maximum size to follow the standard.
