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...
Im currently working on a project and long story short im stuck on getting the nRF24l01 to communicate. I believe I have the Tx side of things working, however as I do not...
Hello,
We have connected Nordic+ MPU 9250 and able to read sensor values through UART display, but we wanted to do some excercises and read values, but it's not possible...
Nice to meet you.
The chip uses nRF 52832.
MDK keil μVision V 5.22.0.0 is used as the development environment.
Since I confirmed the operation with the sample project...
Hello Nordic team,
I'm doing a migration of my nRF51822 (32 RAM / 256 Flash) application from SDK10 (s130_1.0.0) to SDK12.2.0 using the s130_2.0.1. So I took the experimental_ble_app_buttonless_dfu...
The way the example projects, including the app_template are structured, they will only build if inside the SDK folder.
The main problem I find is that the Board Support...
I want to use ANT and BLE concurrently.
I found that there are no multiprotocol examples in SDK12 for NRF51422 (PCA10028). It only have example for NRF52832 (ble_ant_app_hrm...
Hi all,
i use softdevice and app timer.
I know that the softdevice use a RTC0 and app timer RTC1.
I would use a rtc to have a timestamp. but i see that after 512 second...
My function need a time window to get value from sensor,but the prcess always interrupted by SD.I know that the priority of SD is higher than app functions. So how can get...
