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 We have an application where we what to read i2c sensor data over the air to an iPhone. We've taken ble_app_uart_S130 project and grafted in some twi_hardware code. There...
I am interested in the S130 ability to hold 3 central -> peripheral links over BLE, and am looking for some evidence that this has been accomplished with extremely low-power...
I need to get quite a lot of logs and quite fast too. How do I do I get the logs into a file?
I tried with Segger RTT logger, but it tends to give up quite quickly. I heard...
I want my system to sleep for some time, but its waking up and I am unable to understand which interrupt occurred. I want to know which interrupt caused the system to wake...
Hi All,
I want to implement a function to send data from the internet coap client to nrf52840 DK coap server. The nrf52840 runs .hex file which is one modified from Nordic...
Hello, I'm testing an example of a zigby light bulb with a nrf52840 (pca 10056) board.
Here, when I press "BUTNERT 1" on ZED, I want to send the [ON/OFF] status of the current...
The average current during the nRF9160 test DRX is 2.2mA. The period of DRX is 2.56s. Using a China Mobile IoT card. I am testing on the DK board and have turned off all peripherals...
I used NRF24L01 to transmit the data without ACK mode. The receiver received the data normally when only the WR_TX_PLOAD_NACK instruction was used to send the data.If the...
Hello,
I want to set a GPIO Pin to high. Therefore I wrote the code below.
But when the software is written onto the nrf52811, I can not messure any voltage.
I do not...
Hi,
I am going to do data communication between two boards with libuarte. I see that both txdata and rxdata should be uint8_t*. But if I try to transmit the char*, will...
Hi On a nrf9160, I need to send data via UART(E) at 921600 baud. According to the UARTE BAUDRATE register documentation the register value 0xF000000 (Baud921600) leads to...
Hi,
I changed application main.c to enter in to DFU mode after 20 seconds. System is reset every 20 seconds and the boot messages are printed. The message "Booting (0x8200...
I am trying to measure distance with a vl53l1x sensor through the twi_sensor example. I uploaded the code to segger by referring to sparkfun, but twi_handler does not work...
Hi
using sdk17, softdevice132...
There are some parts of the central implementation that I don't understand.
It is based on cle_uart_app_c.
Isn't the function bl_nus_chars_received_outprint_print_called...
It is amazing how common this error is - there must be 100 posts. Yet none solve the problem and none explain it. It suggests that there is some serious work needed to improve...
I've been developing using nRF52840 using the nRF5 SDK. I have also been using FreeRTOS in my projects.
I recently received an nRF5340pdk to evaluate the nRF5340. I have...
