I have received my Rigado BMD-200 BLE modules (nRF51822). Not only have I made a breakout board for the module, I have been preparing myself for my very first ARM development. Before I can install a bunch of toolchains on my desktop, I need one more thing figured out on the hardware front: debugger and/or programmer.I have in my arsenal a couple debugger and programmers: AVR Dragon AVR ISP USBtinyISP FTDI USB-Serial converters You can probably tell I have been hanging out at the Arduino / ATmega com...

Nordic's infocenter

The Infocenter – our new documentation portal - has now been up and running since June and contains all of our technical documentation. We saw the need for this because we wanted to make our complete library more visible, and since the documentation is now found in the one place navigation has become easier, with related content housed together under relevant topics. We’re also making content available in HTML (but, the core documentation is still available in PDF too) which means we can make minor up...

We recently announced that we now support “extended industrial temperature range” (-40 – 105C) on our nRF51822. The devices supporting -40 - 105C are the QFAA (QFN with 256kB flash and 16kB RAM) and the CEAA (WCSP with 256kB flash and 16kB RAM) versions of the nRF51822. There are a few limitations when using the nRF51822 up to 105C. The key limitations are: • Supply voltage range 1.9 V to 3.6 V (compared to 1.8 – 3.6V)• No 1 Mbps non-Bluetooth mode (Bluetooth low energy mode is supported)For t...

Hello Sir or MadamNow i am using NRF51822 of your company. Now we are evaltion thermal character of this component.So please kindly provide theta JC (junction to case) , theta JA (junction to ambient) ,PD(Power dissipation),Tjmax(Max. junciton temperature) to me. Or i will not choose the component trustingly.Best regardsBonnie +86-0512-63487188+86-013862080091...

I'm looking at the ble_app_hrs example and I'm confused about how the drivers are able to differentiate between events originating from various services/characteristics. For example, in main.c under the ble_evt_dispatch we have: void ble_evt_dispatch(ble_evt_t * p_ble_evt) { dm_ble_evt_handler(p_ble_evt); ble_hrs_on_ble_evt(&m_hrs, p_ble_evt); ble_bas_on_ble_evt(&m_bas, p_ble_evt); ble_conn_params_on_ble_evt(p_ble_evt); on_ble_evt(p_ble_evt); }So on any ble event the ble_bas_on_ble_evt function wi...

1. Is it 'NRF_RADIO->TASKS_DISABLE' or 'NRF_RADIO->TASKS_DISABLE = 1'?2. Restarting advertisements seems not to be affected and I guess 'cancels out' NRF_RADIO->TASKS_DISABLE?3. What is the difference with it and simply stopping advertisements?Basically, I am looking to implement a 'radio silent' mode.Thanks....
