I'm using the rRF51 DK with Segger Jtag. In the demo Keil version, I set up Segger jtag to NOT cache memory. When I look at a memory view in Keil, the memory is not being...
Hi
I tried DFU OTA in nRF6310 board as SDK document guided but it cannot work.
Boot loader is from SDK5.0.0 device_firmware_updates project..
SoftDev is v6.0.0....
It appears that the current version of Master Emulator v3.5.0 does not include support for long-writes. I know that SD110 v6.0.0 does support long-writes and my application...

I ran into an issue and i'm trying to understand it better. I was calling the function sd_ble_gatts_value_set(...) from a GPIOTE...
Hello,
We are having some problems with a board that we developed using the NRF51822, see this post: devzone.nordicsemi.com/.../application-halts-on-softdevice-initialize...
New to BLE and nRF51822. I need some explanation and clarification of connections and connection intervals. Can I get a overview of how the nRF51822 or answer some questions...
I get a nrf51422_1.0.0-2.alpha.zip. But why s310_nrf51422_1.0.0-2.alpha_softdevice.hex is bigger than 256K(287K),How can I burn this hex file into the nrf51422 Flash?
Hi,
I am using the nRF51822 evaluation kit, and have been unable to get it working. I compiled the sample BLE Heart Rate sensor program and uploaded it to the evaluation...
