I learned that paring is consist of 3 phase (Exchange of Pairing Information, Authentication, Key distrbution) and TK, STK are generated at the phase of Authentication and...
I have a central application that I need to add a peripheral role to. I don't need to pair or bond in any of my connections, so I based my app on the ble_app_uart_c example...
Hi,
I'm currently running two separate TWI-instances on my nRF52 DK with SDK 11.
Each instance runs quite well with no issue, except for when instance 1 becomes active...
Hi,
When nrf51822 is connected via bluetooth LE to an iPhone application, is it possible to check the actual connection interval (between MIN_CONN_INTERVAL = 20ms and MAX_CONN_INTERVAL...

I'm writing a central app using the pc-ble-driver project with an nRF51 dongle. This is to test our product, which is a peripheral using the nRF51822. The test central needs...
Dear All,
I have developed a BLE system in which nRF52832 is being used as a peripheral and central concurrently. I am also using BLE_GAP_CONN_SEC_MODE_SET_ENC_WITH_MITM...
Hello,
I have board pca10040 V 0.9.0 2015.41. When I program nrf and then issue a nrfjprog --reset -f NRF52 everything works fine, however when I execute nrfjprog --pinreset...
I don't understand OOB used in BLE security part.
Is this a communication out of 2.4 ~ 2.48 GHz frequency band?
Or is this one of method of pairing procedure(to generate...
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.
