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
developer.bluetooth.org/.../runningspeedandcadence.zip
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...
Hi.
I'm developing firmware based on github.com/.../S130_LBS_client_server_central_peripheral example. I installed third party Softdevice s130, and with example of peripheral...
I have modifed the nus_uart(peripheral) to add static pass key in sdk 10.I used my mobile phone to test the functionality and it works as expected[asks for the passkey when...
Hi,
I'd like to put a BLE central in low power between two scan.
actually I use the example Ble_app_uart on a dk board PCA10028
and a second dk board as advertiser with...
Hi,
I am trying to get the SPI Slave working but was hoping to find a how-to. Is there an example of the SPI Slave for the S110 Soft Device (7.3.0)?
Currently, I am...
Hello,
I am developing custom HAL driver for SPI in NRF52 (PCA10040). The problem is that using the EasyDMA MAXCNT registers value must be between 1...255. It implicates...
Hi,
I am using nrf_pwm_noglitch.c from here . Is there a way to stop the pwm cleanly?. I would like to have a nrf_pwm_deinit(); similar to nrf_pwm_init(). Currently I set...
Hi.
I'm using PCA10028, SDK10.0.0, S130.
About "ble_app_multilink_central" for the reference.
This code shows me below sequence.
Scan->connect request->get connection...
Hi,
We have an application where we have very very slow vcc risetime and therefore we have an external watchdog reset circuit connected to the -reset/swdio pin in order...
Hello,
the available QDID for nRF52x refers to Softdevice which has no IoT capability, being this a work in progress.
When this will be ready, will Nordic release a new...
Hi,
I want to use the NRF51822 without the Bluetooth functionality. Is it possible to leave the pins ANT1, ANT2 and VDD_PA unconnected? If no, what is the cheapest way...
Hi,
I'm using PCA10040 board, There i connected the fuel gauge IC via TWI communication.
There pca10040 will acts as master and fuel gauge IC will acts as slave.
While...
