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

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 try to generate a PWM signal on PCA10040 with the nRF52832. To do that I copied the code from the Product Specification into my application, but nothing comes out....
Hi,
I made my prototype board using the nrf51822 chip. for this prototype i use an on-board connector + external programmer to flash the nrf51822 chip.
that's work...
I am looking ahead to the time when I will graduate from using the nRF52 development board to building a custom device with the SoC. The PCA10036 chip will obviously not be...
Hello,
I am almost finishing developement of a BLE module using nrf51822.
For mass production, I hope I can program Softdevice/Bootloader/Firmware to 10 nrf51822 using...
Hi
I want to receive and send a lot of data in a short time (connection Intervall is set to 20ms). And I get the App-Error 0x3004.
I found this definition for the error...
Hello,
I am currently trying to figure out a problem with my mesh. If I stop the event handling of one node, other nodes in the network will fail to send data from this...
PAN #9 in the nRF51822-PAN-v2.4 document provides a workaround for non-functional OUTINIT. This question and this one improve the workaround and state it's unnecessary in...
We have used the first version of the S132 softdevice with the Engineering A version of the nrf52 chip. Now with the newer Engineering B version, we have moved to the second...
Hello Everyone,
i am trying to simulate the circuit using Proteus so can anyone tell me where can i find the Pspice model files for the Nrf51EVB is it available? any suggestions...
Hello to everyone.
I write code for NRF24LE1 using KEIL and rtx tiny. But i have some problems.
When i power on my device, programm don't run correctly, but when hard...
Hi experts,
The softdevice is s120. I get error code BLE_ERROR_NO_TX_BUFFERS after calling sd_ble_gattc_write() several times. I want to ask what does the tx buffer mean...
I have a strange problem on my target nRF51822. When I try and use the UART interface between my nRF51 and my host MCU, it causes the nRF51 to reset and the RTT terminal to...
Hi,
I've been playing with NFC on nRF52. It sends "Security Manager TK Value" over NFC. There is currently no option to use LE SC over NFC in examples, which is to send...
Hello
I have an problem using I2C on my custom board which uses an Nrf51422 SOC.
I have an RTC chip connected to it and I have no idea how to use your libraries.
The...
