When designing a PCB with nRF51, nRF51822 or nRF51422, there are some rules that should be followed in order to get a good working radio/system, with a maximized range.General rule The RF part of the schematic and layout should be a copy of our reference design. It means that not only the component values, but also the geometry, relative placement of the components with respect to each other, and the lengths of the transmission lines should be the same as in our reference design. The reference design for ...

When using nRF8001 with an Arduino board, Atmel Studio is a good free tool to use for development of your firmware. The following video shows a procedure in Atmel Studio in order to enable debugging of Arduino code. It was created with Atmel Studio 6.1 and Visual Micro (Arduino plugin for Atmel Studio)...

Hi, guys. nRF51 IoT SDK is needed Raspberry Pi, so I make the VMware Player Image for Ubuntu 14.04.1 LTS 64bit(linux kernel update to 3.18.3). Even if don’t have Raspberry Pi, can use the 6lowpan!! And it’s easy to develop the linux 6lowpan kernel module by using the VM linux.VM Linux image and "How to" is my website, http://www.hirotakaster.com/weblog/6lowpan-ubuntu-vm-image/Glad I could be of someone help. ...

Hi,I'm developing on a custom nrf51822-based board, and using the s110 softdevice, version 7.0.0. With JLinkGDBServer and the toolchain's gdb, I can debug softdevice-less applications normally.Problems arise when I build my apps on top of s110. Running from flash is ok, but during GDB sessions, my device seems to be reset soon after the call to sd_softdevice_enable(), and my gdb breaks again on the main(). No such reset can be observed when running from flash.In the s110 documentation, I can read, that af...

I'm just reading the documentation regarding the analog digital converter and wonder why there is one bit in the configuration register for every analog input. What will happen when I set more than one bit in CONFIG.D?cheers Torsten...

We are using S130 v0.9 stack,and when BLE device A is connected as peripheral of iphoneand central of BLE device B at the same timeiPhone --> A ---> BDevice A cannot stop or start advertisementThe err_code shows NRF_ERROR_INVALID_STATE when called sd_ble_gap_adv_start()or sd_ble_gap_adv_stop()Device B can start and stop advertisement normally.I asked the same question to support portal, and response is thatthis feature should work but not tested in release (probably not officially supporting?)Nordic...
