Nordic Webcast is our experiment of a more interactive channel between Nordic's staff and Devzone's users. The webcasts give live technical presentations and we will try to answer your questions in real time. The first Nordic webcast explains how to interface with Nordic's Softdevices: What is a Softdevice How to interacts with the Softdevice What you should be aware of when using the Softdevice Walk through an example that uses Nordic Softdevice This first webcast was a test run and was held priv...

IntroductionThis post is an introductory tutorial to SEGGER Embedded Studio. If you haven't already please skim through this post https://devzone.nordicsemi.com/blogs/825/segger-embedded-studio-cross-platform-ide-w-no-cod/ but don't follow along with it. This is the new and improved tutorial using the nRF device pack and assumes no prior knowledge on Embedded Studio.After following this tutorial you will be able to build, debug and run a BLE project on nRF5x devices! You will also be able to load a softde...

[UPDATE (Feb 8, 2016): I have incorporated the feedback that I received from several link-layer wizards in Trondheim.]Last fall I purchased an inexpensive quadcopter that uses Nordic's ShockBurst (SB) radio protocol. The question that I was trying to answer when I started disassembling that poor quadcopter was simple: Can Bluetooth Low Energy (BLE) and the S110 SoftDevice's Multiprotocol Timeslot API provide a link with low enough latency to control a twitchy aircraft? After reverse engineering the...

Hello,im using NRF 51822 with SDK 10 / S110 8.0. Im working on a project that includes one or two timers (initialized by APP_timer function), the ble calender (like discriebed in ble_cts_c) and the ble module. I initalized the ble stack and the inits like discriebed in some of the SKD10 examples. (template, ble_cts_c) and start one timer for time scheduling.When I tested the system without acitiviating advertising start function my time schedule timer runs perfect. BLE stack is initalized at this pointWhe...

MicroESB No Ack

Hi,In micro_esb.h, it is indicated that the transmission without ACK is not implemented yet. However, there is a parameter named dynamic_ack_enable in the uesb_config structure and a function named uesb_write_tx_payload_noack(..) which are not functional yet, when trying to communicating from nRF51 to nRF24.Are you working on this problem ? Is it possible to write with no ACK between two nRF51 ?Regards !...

Hello,I am experiencing some CC register issue in Timer of nRF51822. I am trying to setup TIMER1 for 16 seconds. But I see, that when I try to write to CC registers, the value is cut to 16-bit:write: NRF_TIMER0->CC[0] = 500000; //(0x7A120)read: CC0 = 41248 //(0xA120)I've also tried to write into register manually in debug mode, but seen the same cutting to 16-bit. CC register is 32-bit and this does not have to happen. I know that for some revisions BITMODE limits the length of TIMER0. But I've tried t...
