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...

Hi,
I've been working on a way to detect and prevent replay attacks when beacons are used for sensor data. This is mostly used for home automation sensors, where I have BLE...
Hi,
I have made some changes with how we update tick timer inside FreeRTOS and the results are promising
.
The improvement is
RTOS tick will auto correct if masked...
I went through a similar post for nrf51 which explains the numbers pretty well ( devzone.nordicsemi.com/.../) . I wanted to know what the values are for nrf52. The internal...
We have a nrf51822 device that has to send 6 bytes back to back at 12K8 and 6-18 bytes at 38K4 in the future.
The bytes are in an array and do not need to be generated...
Hi experts,

Hi,
I adapted the ble_app_multilink example to continuously scanning for ibeacons and collecting rssi data.
Data are then sent via UART to a microcontroller which provides...
Hi everyone,
Im new in embedded world so first sorry for maybe stupid or basic questions... Also there is not a lot of information about nRF52840 and IEEE802.15.4 :)
