IntroductionHere are some tips and tricks to manage your application size.RAM and ROM usageThe total RAM usage is: ZI-data + RW-dataThe total flash usage is:Code + RO-data + RW-data ZI-data - Zero initialized data, data variables set to 0 RW-data - Data variables that are different from 0 RO-data - Constants placed in flash This means that if you have a variable defined globally with the const flag it will most likely end up in flash, while a variable that is prone to change will end up either in RW...

 Using PWM and Nordic UART Service on nRF51-DK (nRF51822/nRF52422) to control an RGB LED over BLE.http://electronut.in/nrf51-rgb-led-test/...

Obligatory DisclaimerSecurity is hard. If a product handles sensitive information then it is the engineer's responsibility to his customers to consult a security professional. However, experimenting with security should be encouraged whenever possible; the world needs better security and everyone has to start somewhere.IntroductionThe security features that are built into Bluetooth Low Energy (BLE) are focused on the link between devices. BLE uses authentication to make it possible for a user to pair with...

MITM attacks

Hello,We avoid MITM attacks by using a static passkey. Is it means that the attacker can decrypt the connection if attacker get the passkey? What I transfer or receive data will be captured by the attacker?...

Hello, I have downloaded the nRF_MDK_7_2_1, and open \Keil_v5\ARM\Device\Nordic\nrf51822\Board\pca10001\s110\ble_app_beacon\arm\ble_app_beacon with Keil_v5.I set IROM1 start from 0x0 and size is 0x40000, IRAM1 start from 0x2000000 and size is 0x4000. Then compile the hex files and flash it to the board PCA10001 , I can see the led light but can't detect the bluetooth device. In the debug mode, I found the program stop in the fonction ble_stack_init();...
