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, Dear Expert:
I am an Electronic Engineer. We used nRF51422 or nRF51822 at our products, but found the products was easily reset when did +/-1KV contact ESD testing...
now I used sample code of radio
change NRF_RADIO->MODE = (RADIO_MODE_MODE_Nrf_2Mbit << RADIO_MODE_MODE_Pos)；
In transmitter code , I change
while (true...
Story Short: When trying to run the ble_app_uart example on a custom board with a nRF51822QFAAH0 chip, the code faults and resets at the point in tries to call sd_softdevice_enable...
I would appreciate some suggestions on a good development flow to go from an Example to end application
I have nrf52832 on a custom PCB.
I tested several sdk13.0.0 examples...
Using:
nRF51822

Within the startup_nrf51.s I found something...
The server has no I/O, so no way to press a button.
Can an attribute cause the BLE to set a bit in Flash, so at the next power up, it will read that bit and know to execute...
Hello,
I followed the instructions of KEIL in www.keil.com/.../ulink2_trace_itm_viewer.htm
However, I cant get any outputs in Keil Debug(Printf) Viewer using printf...
I purchased a bunch of ptr8000 boards off ebay from china to do some testing of the nrf905 without realizing they were setup for 433mhz, and I need 915mhz. Looking at the...
Hi,
I am currently testing a DAC with I2S input supplied by the nRF52832.
But unfortunately no signal is coming out from the DAC, furthermore when reading the error registers...
I'm looking to use the nrf open mesh on battery powered devices based on nrf51822. I would like to enable the mesh for short periods of time to transmit values (~50 nodes...
Hi,
I've just got the example running with one DK as ble peripheral and ESB at the same time uing the timeslot API and one DK as only ESB receiver.
I can communicate fine...
I have used following sources for my application:
profile:
-BleManager,
-BleManagerCallbacks,
-BleProfileService
uart:
-UARTService
-UARTManager,
-UARTManagerCallbacks...
Hi,
I've just started to implement the example
github.com/.../nrf51-ble-micro-esb-uart
for the nrf52. And it is now running so I can send and receive stuff via BLE...
