Stonestreet One's Bluetopia how do you request a MTU change?
Or more specifically how do you request an MTU change when operating at the "Platform Manager" level?
More details
============
- I'm using the sample program `LinuxGATM_CLT` which acts as a GATT client and it uses the Bluetopia Platform Manager Framework.
- I'm using TI's WL183xMOD WiLink hardware which uses Bluetopia (previously owned by Stonestreet One).
The API call exists
===================
The function exists, but seems to be at stack layer lower than the PM:
~/src/ti_bluetopia/ $ grep GATT_Exchange_MTU_Request ./BluetopiaPM/Bluetopia/include/GATTAPI.h
BTPSAPI_DECLARATION int BTPSAPI GATT_Exchange_MTU_Request(unsigned int BluetoothStackID, unsigned int ConnectionID, Word_t RequestedMTU, GATT_Client_Event_Callback_t ClientEventCallback, unsigned long CallbackParameter);
But its not callable from the "Platform Manager" level
======================================================
Everything within `BluetopiaPM/sample/LinuxGATM/LinuxGATM_CLT.c` uses `GATM` functions from `BluetopiaPM/include/client/GATMAPI.h`
It feels like the `GATT_Exchange_MTU_Request()` function has not been exposed at the PM level. Its hard to dig deeper into how the PM works because they only ship binaries (doesn't seem to be open-source). For example the only match is the `GATTAPI.h` header file and a binary library file:
~/src/ti_bluetopia/ $ grep -ri GATT_Initialize ./
Binary file ./BluetopiaPM/Bluetopia/lib/libSS1BTGAT.a matches
I feel like the solution is to find methods to report my current Platform Manager `BluetoothStackID`, `ConnectionID`, and callback parameters so that I can call the `GATT_Exchange_MTU_Request()` function directly.
Any help is appreciated, thanks!
