Hi,
Last year, I heard that nordic semi will release a SoftDevice for central that supports mulitple packets per interval time until June, 2015.
For now, I guess s120...
My understanding so far is that the input buffer of GPIO is disconnected by default and we can keep it disconnected for saving power when the pin is configured as output....
Hello,
I just read this paper "High speed data streaming with nRF24L01 " where we can achieve 1.6 Mbps Data Rate in clean RF environment. I am currently using nrf51822 in...
The documentation for ble_evt_hdr_t says that the evt_len field is
Length in octets excluding this header.
However as far as I can tell it's actually the length...
