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...
Hi,
For my custom PCB, I am using the PCA10004 as reference in order to determine if the maximum possible range has been achieved. However, I am seeing only about 20 feet...
Hello I'v just ordered a NRF51-DK kit.
I'm looking at the different tool chain. In my application speed is critical 16Mhz is actually bearly enough, so my question is:...
I have a USB dongle with an nRF24LU1p that has a few SPI pins but is missing the RESET pin. I would like to be able to program it via SPI but the SPI programming protocol...
nRF51 RTX 4.74.0-3
SoftDevice S210 V4.0.1-3
Created a timer for 5 seconds interval.
It turned to be 4.4 seconds. with or without softdevice enabled.
Anybody else has...
Hi,
Access to the UART hangs the execution of the experimental_ble_app_uart_s110_pca10028 example.
The phenomen occures In the file simple_uart.c when checking for the...
This may not be a major disaster,but it bothers me:
I have written an application to read data from an ADXL345 accelerometer (using SPI) and print out the data on a console...
Good morning,
i still couldnt find out if it is possible or recommended to use the PPI together with the s110. i checked the example in the sdk documentation but it was...
I have an in memory log variable that I write to on various BLE and device manager events. If there is ever a serious error, my implementation of app_error_handler() now takes...
Hi,
I have programmed the radio_test_example to target having nrf51822 qfacaa chip. I have changed the UART pins as per the custom board.
It's working fine but showing...
Hi,
How can i wake up(interrupt) the nrf51822 device from "air" (from my iPhone application)?
For example after i paired iphone with nrf51822 i want to put the nrf to sleep...
I am using SDK 7.1 and I am attempting to use the Makefile.common found in sdk_7.1->components->toolchain->gcc->Makefile.common. However, the Makefile.common appears to contain...
I'm trying to send multiple 20byte notifications per interval through the NUS usart service to iOS 7.0, 30ms conn. interval in the UART demo app. It seems I cannot tx more...
Hello,
I'm working on a project with SoftDevice s120. I played with the project ble_app_multilink_central. The maximum number of characteristics per service supported by...
Our application includes a 32.768 kHz crystal oscillator with a nominal +/- 20 PPM accuracy. When I factor in aging over 10 years and worst case variation due to temperature...
Hi !
In questions question1 & question2 Petter Myhre gave a complete answers about count of max characteristic per service in s120 and how to resolve this restriction....
