why use 50ms and 400ms connection interval for testing the maximum data throughput(2M,247byte payload)?
Because 50ms can only send a pdu , and 400ms can send up to 8 pdu...

Has anyone experience of successful TICK_DV calibration for nRF9E5? What order of accuracy should be achievable?
In my application I maintain a software RTC clocked by...
Hi,
I want to periodically send data through nrf8001 so that once the connection is established for a particular service, i can periodically send data . So how to create...
Hi nordics!
I want to using app_data for preserving data.
For that.
First, I change the value DFU_APP_DATA_RESERVED to "0x0400"
Second, I change the memory start...
I have the "old style" nRF6310 board + nrf51422 boards.
I want to test different examples from the latest sdk, and possibly with different softdevices as well.
I appreciate...
