Hi, I attached here some slides that we used in our technical seminar for DFU. Download the presentation here: DFU_SDKv8.0_Pub.pdfThe presentation covers: What DFU is and what bootloader does Two types of DFU, single bank and dual bank update Some animation explaining how DFU works on both cases How do we do Softdevice update DFU command sequence chart It was heavily based on the SDK documentation you can find here. There are much more detailed information in the documentation. I exported the pre...

The NRF51822 Bluetooth Low Energy mbug board from y5 Design is an easy to use ARM Cortex-M0 microcontroller with BLE. This board can be used as a standalone system or stacked with other mbugs to create multifunctional systems. Part of mbug™ ecosystem Smaller than a quarter, atapproximately 0.9" x 0.9" Can be used as a standalone microcontroller or with other mbugs (sensors, displays, relay, servo, battery, etc.) 12 different mbugs (2 processors, 9 expansion, 1 prototype) stackable 1...

 Bluz is a brand new development kit that brings Bluetooth LE to the internet. We have paired up with Spark and ported their FW to the nrf51822, allowing Bluz to be controlled and programmed over the air from anywhere in the world. We will release several gateways that allow bluz to always be online, even when smartphones aren't nearby.We have launched Bluz on Kickstarter, so you can pre-order bluz and accessory shields and gateways now: https://www.kickstarter.com/projects/264813863/bluz-bluetooth-m...

Hello,for my sensor I need to have a delay BEFORE pulling CS high. So I would like to add an argument to the spi_master_send_recv()function that give me exactly this possibility.But I am not 100% sure where exactly the chipselect pin is triggered..I tried my best with the debugger and found this line nrf_gpio_pin_set(p_spi_instance->pin_slave_select);inside this function: spi_master_send_recv_irq()But I have really no clue how this function is called and how I could add my argument to this call....

Hello,I need to get RSSI with the NRF51422 (pca10031, S110), but i don't want to connect with a central device (i.e. Smart Phone). The central device should scan for bluetooth devices and the NRF51422 should measure the signal strength of the received scan response request packet from the central device.Is it possible? If yes, how is it possible?I'm using SDK 8.0.0 and S110 V8.Thanks in advance...

HiI am trying to change the radio's transmit power in program, but I can't solve it. I downloaded nRF51822 Beacon v1.1.0. and am testing PCA20006. (Source Code\nrf51_beacon\ble_app_beacon\pca20006)I am making an admin program for iOS7 device to configure advertising interval and power level.First of all, I could not find where is initial setting of transmit power level. Even though I changed most of setting related power level, it does not work.Secondly how to set Power Level of nRF51822 from iOS? I searc...
