After successfully managing to preserve our devices bonding information (and custom app context data) across DFU updates, we have a few related questions.
I should...
I've just got up and running with the nRF51 DK. I've had a play with some of the examples, and now I've started on my own project using ble_app_template_s110_pca10028 as a...
After startup, I was able to send a spi msg from the master (app chip) to the slave(nordic). But when I try to sent the second message, I did not get any response from the...
I am using the SPI Slave peripheral and attempting to send the nrf51822 bytes from another MCU.
Am I right to assume that there is, basically, a 256 byte max per transaction...
Hi,

Hello:
Im rewritting a program from ST32F105RC to NRF51822.
In a part of the program of ST32, it checks if the interruption from pins 5-9 (EXTI9_5_IRQn) is enabled, and...
Hi,
I worked with temp sensor example and sofdevice s110 and something stuck on some function.
Anyway, I made readout from registers but softdevice blocks register access...
My nRF51 will occasionally lose connection to the computer, and I have to disconnect and then reconnect it before it will work. How can I reset the device dynamically, without...
I'm trying to compile a project I have for nrf51 on nrf52. I am running into errors with macros not being set.
For example:
