Mm-iot-sdk-2.7.2 is missing functons: eg: 'mmwlan_tx_wait_until_ready'

I am porting our IoT platform to 2.7.2.

It seems that the following functions are missing:
mmwlan_set_health_check_interval
mmwlan_tx_wait_until_ready
mmwlan_alloc_mmpkt_for_tx
mmwlan_alloc_mmpkt_for_tx

Here is some info to provide context:
I checked all “.h”, “.c” file and the morse libraries . None of the
above functions could be found. Below is my search for ‘mmwlan_tx_wait_until_ready’

Pulled repository, get 2.7.2 branch
git clone --recurse-submodules GitHub - MorseMicro/mm-iot-sdk
git checkout 2.7.2

Do find for .c and .h files to find function.

find . -name "*.h" -exec grep mmwlan_tx_wait_until_ready {} \; -print

enum mmwlan_status mmwlan_tx_wait_until_ready(uint32_t timeout_ms);
status = mmwlan_tx_wait_until_ready(MMWLAN_TX_DEFAULT_TIMEOUT_MS);              '
./framework/morselib/include/mmwlan.h
============================
 find . -name "*.c" -exec grep mmwlan_tx_wait_until_ready {} \; -print
status = mmwlan_tx_wait_until_ready(1000);
 ./framework/src/mmipal/lwip/mmnetif.c


Look in libraries for function:  mmwlan_tx_wait_until_ready

Hi Straff,

Not sure what’s happened for you - but all the listed symbols are definitely present in the code section of libmorse.a for the cortex-m4f. See below

Can you check your libmorse.a sha256sum?

Thanks for the idea.
I got tricked by Meld, which said the files / directories were the same.
But actually, it ignored the .a files.
