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...
I met a big issue when implement the voltage level switch. I used nRF52832's SPI to communicate with an ECG sensor which has 1.8V SPI. The issue is that, 3.3V signal from...
Having just got the DFU functionality working I got the task of trying to add NFC functionality to the application. The code side was not a problem since I got a c and h file...
According to the BLE 5.0 Specification :
"The Link Layer shall use the primary and secondary advertising channel
indices as specified by the Host, and the used primary...
Hi,

Hi,
I am using ble_app_multilink_central and ble_app_uart central example for my application, i am combining these two example for ble_app_multilink_cenntral for BLE_NUS_C...
Hi,
I'm using the nrf_drv_twi driver (master) to communicate with a number of IO components, such as LEDs, buttons etc.
If my IO component does not respond (why is not...
I downloaded SDK 12.3.0 (seems to be it is the last supported SDK for PCA10028) and tried to use fats example, I changed pin configs to SPI's pins.
I also prepared my 16Gb...
Hi there,
I'm putting together a PoC board for a demo - in this case size matters and I've had to make some compromises for the sake of speed (which have increased footprint...
Hi,
After setting up constant carrier, how can one determine that it is working. With no modulation the receiver can't determine anything, can it?
thanks
Hi,
SPI use with SDK14.2.0 leads to very high power consumption (around 400 µA) on nRF52832 (QFAA). The same piece of code running with SDK12.3.0 has much lower power consumption...
We developed a device based on nrf51822.
We use SDK11 and module Device Manager to implement bonding.
We have received feedback from the user, that our deivice was bricked...
Hi,all :
I just want to know how to enable the nrf_log (in the ble example).The version of the sdk is 12.3.0 and the cpu is 51822 .Thank you very much .
On the nRF52810 is it posible to change the gain setting for the SAADC on demand? For example the SAADC is reaching its cap and then the gain is increased so it is posible...
I see the max for a BLE connectable advertising packet of 31 bytes. I am not sure if the manufacturer specific data which also can be up to 31 bytes is included in the overall...
Hi,
We have recently moved from using the nRF52840 PDK to a custom PCB. The custom PCB uses nRF52840 Q1AABB, while the PDK has Q1AAAA.
On the custom PCB, the code is getting...
