This library has been written for the following bluetooth module : HC-05, HC-06
RAM can contain approximately 50KO of data. Each message can't do more than 32KO
You can't send more than 1ko -including header- from your smartphone to the calculator. In fact, the reception buffer has a size of 1ko max.
Without the header : 1000 - 48 = 952o
for sending : 256-48 = 208
Without the header : 1000 - 46 = 954o
for sending : 256-46 = 210
If the 32 ko buffer is full, it will return a FUL packet.
