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...
Hello.
we are using the nrf51822 and doing the approval of the radio transmitting equipment model.They refer the modulation mode,as the picture:
I am asking:1、can the modulation...
I'm working on a central device. I'm using 52832, SDK11, SD2.0.0
I accidentally used a peripheral device that doesn't have the right service UUID that my central device...
I'm using nrf_delay_ms to trigger a series of beeps though a speaker using PWM, but I seem to have intermittent problems with this when the device is connected.
Basically...
I am trying to get fstorage to work, but I seem to miss some of the symbols needed: "error: 'NRF_EVT_FLASH_OPERATION_SUCCESS' undeclared". These are declared in softdevice...
Hi all,
I am using a BLE nano 2, which is based on the nRF52832. I am trying to measure small capacities of a few pF with this method:
wordpress.codewrite.co.uk/.../...
I want to connect a central and peripheral and only have ble on when the peripheral senses a certain event that exceeds a threshold. Do the devices need to connect on startup...
Hi Nordic,
I’m H/W engineer, dedicated in development of radio circuit. I ask the question because we’d like propose your Nordice nRF52840 to our customer when replying...
I am developing an application which uses 2 nrf52 running sdk 12.3 and softdevice 132 V3.
The central device appears to be saving and whitelisting the two peers, but it...
Hello!
We designed and manufactured board with nRF52832_QFAA. The NFC pins was configured as IO and connected to sensors. The problem is that we see that those pins get...
Has any-one been successful waking up a sleeping 328P via a NRF24L01 PRX IRQ interrupt?? My scenario is as below.
Establishing a two way communication between two arduino...
Color sensing not working after DFU. No color reflection LED activity noted. I would like to have more detailed info on how the color sensing code translates the raw color...
Hello.
I need to use LESC numeric comparison pairing.
It seems that the PIN is automatically and ramdomly generated after the connection occurs.
I would need to manage...
I am running a nrf52 with IOT sdk's Cloud CoAP example. I am wondering about the parameters that I would need to integrate this into a product. These include the stack size...
