9.4.1. Maximum data throughput

The following table contains the measured maximum throughput values for user payload. The
test setup is as follows:
• Two Proteus-III radio modules connected to a fast micro controller (STM32 on NUCLEO-
L476RG)
• Radio mode as specified in the table below (125 kb/s (long range mode), 1 Mbit/s or
2 Mbit/s)
• Fastest connection interval of 7.5 ms ( RF_ConnectionTiming equals 0)
• Fastest UART baud rate of 1000000 Baud ( UART_ConfigIndex equals 33) with HW flow
control
• High throughput mode to transmit 964 Bytes payload (i.e. 4 radio frames, each with 241
byte payload) per connection interval (Bit 0 of CFG_Flags )
