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.

Hi,
I am working on ble_app_uart_c example provided in SDK12.3.0 with S130. I tried this example on PTR5518 ble chip but suddenly device goes resetted every time.I am printing...
I'm finding rather high power consumption developing freeRTOS on the nRF52. I have it found that it appears Task's are suspending properly on the main BLE thread (copied from...
Setup
I was just looking through the code in the HIDS module in more detail, now that I have built a few demo HIDS apps I want to make sure that I understand the HIDS module...
Hi,
Is there any other define to change than SERVER_COUNT in main.c of client's light control in order to run the example with only 1 client and 2 servers (instead of 3 servers...
I cannot get the output from the is the example the UART buffer gets filled but there is no output to the tty.
The interrupts seem to be set, but I don't see the interrupt...
Hi
I am using nrf52840 for indoor positioning application based on RSSI. I was wondering if somebody has a tip how to calibrate the nodes before doing the experiment.
Hi,
I'm using sdk12.3.0 ble_app_uart.
My problem is BLE connection.
Sometimes(almost 50%)I tried to connect BLE but fail and I have to connect again.
I don't know...
Hi, I'm contemplating ways to drive a small RGB LED matrix with the nrf52832 in a really space-tight project. Ideally without any external components. I'ts maybe around 40...
Hello,
I need do synchronize the time between two NRF52 devices. One is connected to the other by a custom BLE service. Do you have any ideas how this could be done?
...
I'm trying to integrate buttonless DFU with secure bootloader with bonds with the DFU.
Using SDK 14 with SD 132 v5.0.0.
Using projects: secure_dfu_ble, ble_app_hrs_freertos...
Hello:
When I try to open an example project from nordik, keil doesn't open some files and I get the following error:
"no source": Error: #5: cannot open source input file...
in main() I initialize the timer
// Initialize the clock module
ret = nrf_drv_clock_init();
APP_ERROR_CHECK(ret);
// Request the low-freq clock to start N/A for SoftDevice...
SDK v12, SD130 on 51822.
I init uart through APP_UART_FIFO_INIT, and installed uart_event_handler. UART rx/tx with an external MCU works OK while softdevice running.

Hi. I have some nRF51 firmware I'm migrating to the nRF52. It's a peripheral with bunch of vendor specific services, using SDK 13.0.0 and SD 132 v4.0.2.
My code builds...
