Recently worried about how to download nRF51822 and STM32F405RGT6 in the Xubuntu system, today finally downloaded successfully, recorded the process of resolution.After entering the virtual box VM Bitcraze shared, go to the following directory:Cd/home/bitcraze/projects/crazyflie2-nrf-firmware/We will find the makefile file,#Put your personal build config in config.mk and does not COMMIT it!-include config.mkcload_script? =. /crazyflie-clients-python/b

The previous article analyzed the code of the first 10 basic experiments, starting from here to analyze the next 10 ~First, the PPI principle:PPI (Programmable peripheral interconnect), Chinese translation is a programmable peripheral interconnect.The PPI approach is set up inside nRF51822, allowing interconnection between different peripherals through tasks and events, without the need for CPU involvement.The PPI allows tasks and events to be connect

" (0X3E) error occurs if the master was unable to receive a packet from the slave within the first 6 Connection events after sending a connection request. This could is caused a number of reasons. Here is a few possibilities: The RF performance on one or both devices are not good, so the slave either never receives the connection request, or the M Aster never receives any packets from the slave during the first 6 connection events. The RF performance could is bad due to a failed CRC, col

BLE-NRF51822 tutorial 9-dynamic password (pairing code) NordicBLE technology exchange group 498676838This tutorial also describes how to modify the dynamic password (actually a pair code) based on the uart example in the sdk. The Uart example is in the following directory: XXX \ Keil_v5 \ ARM \ Pack \ nordicsemicondu\ nRF_Examples \ 9.0.0 \ ble_peripheral \ ble_app_uart Some theoretical knowledge about pairing is introduced in the static password tut

BLE-NRF51822 tutorial 5-static password settings NordicBLE Contact Group 498676838This lecture introduces some related theoretical knowledge about pairing and describes how to set a "static password ". The program is a uart demo Based on sdk9.0 In addition, the mobile app used for testing is lightblue in IOS. The correct statement here should be a pair code, not a password. Enter this pair code as an optional part of the pairing process. Before intr
