Hello
I'm testing nrf52820 longrange speed, but it's faster than my calculations. Will it automatically turn on the fec?
This is my config below.
m_adv_params.primary_phy = BLE_GAP_PHY_CODED;
m_adv_params.secondary_phy = BLE_GAP_PHY_CODED;
Below is the bag I grabbed, s=8
Test speed
This is my calculated theoretical speed(send packet 244Byte)
send packet need time
access address + ci + temr1 + pdu（header+payload）+ crc + term2 = 32bit+2bit+3bit+(244+3+2+2+2)*8*8bit+24bit*8+3bit*8 = 16445bit
speed = 16445bit/125kbit = 131.56ms
empty packet need time
access address + ci + temr1 + pdu（header）+ crc + term2 = 32bit+2bit+3bit+2*8*8bit+24bit*8+3bit*8 = 381bit
speed = 381bit/125kbit = 3.048ms
send speed
244byte/131.56ms+3.048ms+150us*2 = 1808Byte/s
But I got 2.8kbyte/s so I think i make something wrong. Can you give me some advice?
