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...

The following is the estimated nRF51 current consumption during advertising with the DCDC disabled. Advertising 1: TX power: +4dBm adv interval: 20ms (minimum advertising interval in normal adversising mode) payload: 10 bytes application processing: 2ms each adv interval.Average current consumption: 1794 uA Advertising 2: TX power: +4dBm adv interval: 1200ms payload: 10 bytes application processing: 2ms each adv interval.Average current consumption: 33,4 uA Advertising 3:...

I have 4 buttons in my circuit with a nRF51822QQAC (a RAYTAC MDBT40 module on a custom PCB), I am using a very simple printf to check which ones are pressed, the internal pull-up resistors are all enabledOne of the 4 buttons appears to be stuck, always reading lowConnecting the stuck signal to VCC makes it read high and does not cause a brownoutThis happens on all 3 identical PCBs, so I'm sure it's not physically shorted to groundThe pin in question is P0.00Why is the internal pull-up not working on this ...

Hello, I'm fairly new are Nordic and have inherited a good project from a departing coworker. We are using Keil uVision 5+nRF51822+BLES110 softdevice. She explained her design to me by telling me that we cannot write to ble_flash while we are advertising or connected. She also told me that this issue may be resolved in an upcoming API or SoftDevice upgrade.Is this true? Is it currently possible or will it be at some point to interact with Flash while connected?Thanks....

Hi,Thank you for looking into this issue.The target BLE module we are using is a custom board (Rigado BMD200) based on nRF51822 s110 chip. We have tried a few example projects such as the ble_app_hts on the module.To test the module, we have downloaded the nRF Master Control Panel on devices including a Nexus 5, a Nexus 7 tablet, and a Asus Zen phone.From the master control panel app, we are able to connect to the module and discover services except for Nexus 5 (runs Android 5.1), where none of the servic...
