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:...

Hello! I trying to send message from peripheral to central. On peripheral characteristics are changes with delay. To change characteristics I use this function: void send_char_data(char *data, char size) { ble_gattc_write_params_t write_params; uint32_t err_code; write_params.write_op = BLE_GATT_OP_WRITE_CMD; write_params.handle = m_char_handles.value_handle; write_params.offset = 0; write_params.len = size; write_params.p_value = data; err_code = sd_ble_gattc_write(m_conn_handle, &write_params); APP_...

Hi. I am haveing trouble with the SD looseing connection to phone/ipad when I enable a power converter placed closed by. When I sniff the communication with the phone I can see that the NRF stops awnsering the packets from the phone. As shown below![image description](/attachment/f5a022b56e897b1cfdba57fce1005e14)Notice that first no packets are dropped and then all packages are dropped.I am sure that this is some how related to EMI as I can disconnect the load the the power converter and I never get disco...

Im using the PCA10031. Placed it in the my laptop usb and installed the nRF go and keil mdk arm and nrf51 sdk.Using the pack installer, which example should I use to be able and detect ble device using my cell phone (nexus 5)?...
