Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
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!
When collecting dc1.4v with SAADC, there is an error of 100uv. SAADC is configured in differential mode, with N-terminal connected to GND and p-terminal connected...
Hi,
I've read in these forums and seen the machine instructions within the C code that nrf_delay_us (which BTW is used to do nrf_delay_ms) is implemented by executing a...
Hi team,
I would like to know the default channel used for data transmission and the frequency of the channel.
Also whether the frequency is configured in the softdevice...
What is the purpose of the external capacitors on DECA and DECN? DECA calls for 1uF and DECN calls for 0.1uF. The datasheet calls these out as "Regulator Supply Decoupling...
Hello,
sorry to border you again, but I have a problem that block me for many days. I read all nordic questions on TWI (I2C) but did not found a solution... :(
I have...
Hi,
We are designing a custom Board using nRF52840 SOC.
We are operating it in Normal mode, using an internal DCDC converter
We have used configuration 5 from the...
Hi there,
I need to transmit 33995520 bytes from nrf52 peripheral device to a Windows/Android device. Currently it takes about 13 to 14 minutes to complete the data transfer...
the flash of the nrf52832-QFAB is 256KB. the softdevice S132 is used which consumes 152KB and the compiled file of the BLE_UART only consumes 98KB (after making the changes...
Hi,
We have a product already on the market for about 2 years, based on nrf52840 and nrf52832.
The product receives data from an 'external device' via UARTE, forwards...
I received the product update notification via email. I did not see any additional details such as a PCN which documents the exact changes.
So the questions I have are:...
Hi Devzone,
I have noticed that some examples, like "ble_app_hts" that has strange flash placement like this figure:
There are 3 partitions, each is 8 bytes in top of...
Hi
I was using the MESH SDK 5.0.0 Dimming Server Example on nRF52840 DK and Dongle it worked fine so i designed a custom Board according the Designrules of Nordic. ...
Hi
I want to measure the battery power by using SAADC to measure the value of VDD,The battery to be considered is 4.2V or 3.7V lithium battery,How should the circuit be...
