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...
Hi!
Is there any configuration differences between those 2 modules??
I understand from the data sheets that the pinout is just the same.
I´m testing a PA+LNA on the same...
bnjr, je veut mesurer le rssi entre deux composantes BLE Nano . quels son les fichiers .h qu'ils faut ajouter pour le faire fonctionner ?
merci a l'avance

I tried to program the beacon kit with the nfr51822_beacon_app.hex through DFU-OTA using the nRF Toolbox on an IPad, and though the upload seemed to work, the application...
How do I configure nRFgo to use the IAR I-jet rather than a segger? When I run nRFgo the nRF51 Programming tab is greyed out and it says no board connected. I presume this...
Hello, I use two nRF24L01+ modules as a transmitter and a receiver, and Atmega8515 as my microprocessors. The transmitter seems to be working as I can see the modulation on...
Hi,
Our manufacturer would like to change the recommended capacitors on the nRF51822 antenna circuit design. Here is the query:
Please check below 3 capacitors request...
I notice in the datasheet for the NRF24L01+ that the receive address needs to be programmed into the Receiver.
Our application receives data from another channel and supplies...
Hi All,
I am looking for a cost effective Chip Socket for nRF51822. The challenge with nRF51822 is that while it is the standard QFN48 package, the pitch is 0.4mm making...
hello,
I have known that Nordic has produced new nRF51 DK which already support s130. But it seems only a demo!
What's the exactly plan of BLE 4.1 and 4.2?
When can buy...
Since windows xp isn't supported any more, I need to get the evaluation kit working with a windows 7 PC. It looks like the problem is with the USB communication. Is there...
Hello,
I am using ESB protocol and there is a definition says "#define NRF_ESB_CONST_MAX_TOTAL_PACKETS 6" so how can I use maximum total packets number? I am looking higher...

I am using SD 8.0 SDK 8.0 and MCP 3.8 I am able to find the DFUtarg service and successfully complete the transfer of my applcation (100% complete). However, upon finishing...
Hi,
I'm doing some throughput/current consumption tests with nRF51822 (on PCA10001).
My firmware has been developed starting from hrm example. I have created a custom service...
