how can I synchronize...
I have read through the forum on this and I am still not completely clear. Here are my questions:
Can I create characteristics that are larger than 20 bytes? The Bluetooth...
In looking at the nRF51 UART Example I'm wondering about data loss over the Bluetooth interface.
When bytes are sent to the host, is there a re-transmission mechanism somewhere...
