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...

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...
Is there a calling context restriction for sd_ble_gap_connect()? Either in the function call or where the peer address pointer is in memory?
I based my Central project...
Hi everyone,
I tried to test nRF51-ble-app-uart-static-passkey to learn the static passkey method.
I used PCA10001 EK board, with S110_7.1.0 and SDK_6.1.0.
Well, if I connect...
The maximum data length of a characteristic is 9, and I use the follow function to send the notification to a client
uint32_t dxs_send(dr_ble_dxs_t * p_dxs, uint8_t * p_data...
Hello,
I am debugging through UART with nrf52 and s132 softdevice using Keil V5 for the proximity app. When I flash the example app from the 9.2 SDK and look at the debug...
Is there a migration guide for the SDK 10 somewhere? I think the use of the APP_TIMER_DEF() macro is one thing that should be in it. Took me a while to understand why the...
Hello There,
As mentioned in the S132 specification (S132_SDS_v0.5.pdf), when acted as a peripheral and the connection time interval is 7.5ms, for the case of a GATT server...
I am running Windows 7 Pro SP 1 64 bit and have gong through the tools installation procedure, in particular running nRFTools_7_7_0_Installer.exe. This ran the J-Link V5.02...
When building a solution that supports Bluetooth MAC address randomization are there any options available in nRF Sniffer to allow packets to be captured. e.g. potentially...
Hello,
I do connections between nRF51 in my application.
When the central detect an advertising frame, it ask to a server is the device is allowed (few ms). When server...
I am very familiar with the arduino side but the BLE is brand new to me. I was wondering if I can use P0.00 and P0.01 to talk to the arduino and if its possible how exactly...
Hi,
As explained in devzone.nordicsemi.com/.../ I want to interface my Beacon to a Invensense sensor with I2C. I'm having a hard time about using the I2C drivers/examples...
