ARM C library is really good at optimising out calls to underlying
seek. The only ones we were actually detecting in the empty file case
were the ones that the default FileHandle::size() made itself during
the SEEK_END case.
When we implement TestFile::size() directly, we will no longer see
a single seek call from the ARM C library in the empty file case, so
remove those tests.
Beef up the non-empty file case, adding checks that we are making
underlying read+write calls in the correct position, as a proxy for
direct checks for underlying seek being called.
In QUECTEL_BG96 and QUECTEL_BC95 there was missing #ifdefs for
PPP mode and our stack was used. Also BG96 needed to be added
AT_CellularBase::AT_CGDATA as not supported.
StackTop calculation was not adjusted when ram size was increased by using al 3 ram regions.
This caused memory allocation failures althogh enough free heap was reported
If sequence from buffer contains tag but symbol before tag is same as
first symbol of the tag, then the tag wasn't detected.
For example, "\r\n" tag was not found from "\r\r\nOK" sequence.
Fixes the following warning
[Warning] toolchain.h@24,0: #1215-D: #warning directive:
toolchain.h has been replaced by mbed_toolchain.h,
please update to mbed_toolchain.h [since mbed-os-5.3]
1. Change camelcase variables to Mbed OS style.
2. Remove functions declarations from the `_alt` header, since they
are now added from the module header regardless whether an alternative
implementation exists.
3. Remove the `extern "c"` declaration from the `_alt` headers.
4. Remove redundant extra lines.
Unittest stubs needed to be updated for the API change.
Although this API is private and internal to LoRaPHY, somehow it
appeared in the LoRaPHYStub. Updating it for consistency.
A new algorithm has been taken in use to calculate the receive window
length and the timing offset involved in opening of the said receive
window. This algorithm performs better than the stock algorthm and
consumes less power.
