I am now trying to communicate with custom profile of BLE between two FRDM-KW41Z board.
I have a document called "Bluetooth Low Energy Application Developer's Guide".
The developer's guide has a chapter "8. Creating a Custom Profile" but it is not useful for me because it just explains the sample code, temperature sensor and collector's case.
What I want to do is "send 32bytes of data,
for example, from temperature sensor to collector" by modifying the sample code.
Could anyone give me suggestion or advise?
Thanks,
Tomo
