Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
i made this project to try to create RSC service on arduino

unfortunately the server starts but i'm not able to...
Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
By combining some examples, I'm starting to understand how the UART examples works.
Using Keil 8.0.0, and the PCA10003 Board, I'm trying to send a burst of messages over...
I can see and bond nrf51 with android, but with iPhone nothing.
What can i implement for see nrf51 with iPhone?
Can i pair Iphone and nrf51?
Sorry for the very bad english...
The new generation of nRF51822's have a few neat new features, particularly the automatic power management piece, that I would like to potentially leverage in our project...
Hello,
I'm seeing some 67.2kHz reference spurs on the RF signal when I'm turning on the constant carrier mode using the DTM interface on the nRF51822. Layout and circuit...
Two applications using the same softdevice, s110, blinky and beacon from the examples.
Flashing softdevice and beacon successfully.
Replacing beacon app by blinky successfully...
The bootloader in SDK 8.1.0 (at /nRF51_SDK_8.1.0 examples/dfu/bootloader) calls pstorate_register() twice. The first time as part of bootloader_init(), then on bootloader_dfu_start...
hi,
I have implemented a UART to receive network packets from another controller to send it over BLE.
UART config are: 8bits data, 9600 baud rate, no parity, HW flow...
Hello,
I am wondering wether I need to pass regulatory tests when I use the S130 Softdevice together with a 3rd party module such as the one offered by raytac ( www.raytac...
Hi,
So i don't have any experience of working with nrf ble chips, but i was given nrf52 DK and i need to make it work as an iBeacon. So i got the dev board working without...
I'm planning to implement a mesh network, where each node (ble device) also acts as a scanner, detecting BLE advertise messages. The mesh network would then forward the advertisement...
I noted on the release notes for S110 v8 (DRGN-5556, NRFFOETT-986), that enabling/disabling blue_radio_notifications() while the Stack is not idle can cause an assert. Does...
I need something in excess of 5mA output drive. Is there likely to be any problem with connecting two or more GPIO pins in parallel(providing I use OUTSET and OUTCLR to ensure...
Hi,
I have created a project with Keil 5.15
The simply blink app works. Now I want to play with softdevice.
The only problem is... no matter what I do, my hex file always...
