Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
An external PA/LNA is used to extend range of nRF51822, and S110 is used for BLE, How to switch between PA and LNA? and how to disable PA/LNA when there isn't transceiving...
Hi...
Can anybody help me to run ble_peripheral example (ble_app_hrs for S130). I have build and load the code successfully but cant see the advertisement. But while debugging...
I am working with the nRF8001, and I'd like to create a services.h file that will let me broadcast battery level and as well as allow temperature to be read by a peer.
...
I have been able to successfully load and run a colleague's firmware (worked perfectly) and make my own modifications (worked perfectly) but after recently leaving it powered...
Hello,
I am trying to design a power supply circuit for my project based around the nRF52 and various sensors. I need to use the 5V pin so I will need a bigger battery...
Hi,
I would like to estimate power consumption in central(master) mode. However, power profiler in devzone.nordicsemi.com/.../ only provides power consumption in peripheral...
We're encountering a frequent but intermittent hang after handing off OTA DFU to iOSDFULibrary 3.1.0. In the happy case, the characteristics are discovered and DFU process...
We are using the Android nRF toolbox v2.4.0 and have successfully implemented the Template app. The app will reliably connect with our device and functions well. The only...
Hey,
I was on one of the meetups when nrf52 was presented. You guys used a mbed shield for demos. Do you have code example and what pins you were using for connection?
I am working with the PCA10028 board, SDK 10.0.0, and s110 8.0.0. I have created a characteristic that is "coupled" to LED2. When a connected central writes a value to the...
Hello,
I want to store temperature samples in flash of nrf51822. I am using pca10028 and sdk 12.2.0.
I have the code for writing,deleting and reading from flash memory....
Hi, All!
I am using nRF51822QFAA with 16KB ram, and S130(sdk 11) for the dual bank bootloader, reference to the s130 releasenote, I config the ram memory start at 0x200013d0...
Hi,
I have tested several BLE examples in SDK12.30 and they would not compile, what's the problem?
for example here is the output of ble_app_uart example.
*** Using...
Hi,
Using this doc it says the SPI supports 16 bit frames. Is this true for the nrF51822 BLE Nano? I found that the mbed API does not support 16 bit frames doc . Can I...
Hello,
I tryed to find in Q&A something that can help me understand how it is possible to measure battery voltage with nRF52, but i am not sure i found the exact explanations...
The v3 reference manual of the nrf51 mentions:
"[The powerfail comparator] also provides hardware protection of data stored in program memory by preventing write instructions...
If I use the interrupt handler to set Flag, and read sensors and write data to SD card in the main loop as in the following code then everything works well.
#include <Wire...
