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 currently have a custom service emulating the batterey service. I have added an extra characteristic to recieve data from the central in the same way as ble_app_uart. the problem is they both use handlers with different formats, for ble_app_uart typedef void (*ble_uart_data_handler_t) (ble_tx_t * p_nus, uint8_t * p_data, uint16_t length);and for batterey service typedef void (*ble_tx_handler_t) (ble_tx_t * p_tx, ble_tx_evt_t*p_evt );Can the service use both of these handlers together? The application wo...

I was trying to calculate analog voltage in nrf51822 through ADC.I used analog 2 pinref voltage =1.2vpre scaler = 1/3so while i connected 0.9v to analog pin. I see analog result as 0xDB.I was trying to calculate voltage through formulainput voltage = 1.2v * (1/pre-scalar)*(ADC_RES/256).My voltage doesnt match to ADC_result.Can you please provide me solution for calculating input voltage?...

Hey I'm developing a sensor network using ANT shared channel. Here are my set up: 1) I'm using a Android tablet as master. The app was modified from aquired channel app from sdk. What I did is - Modify the ANT config so it is ANT shared channel - Loop a broadcast from adress 1 - 5 in the Channelhandler when channel event is TX 2) For the sensor I used a nRF51422 system which config to send two broadcast data back to master in every 5s period. 3) the channel freq is 4*5=20hz, I put a delay about 1s after s...
