Using one ADC, the current can be reduced to about 40uA after the ADC value is taken. Using a two-channel ADC, after the ADC value is taken, the current stops at about 0.4...
I'm searching for a software engineer who can help us getting OTA support between nRF52810 and PIC16 MCU.
nRF52810 must have command- and data mode over UART, Pic controler...
I want to be able to read the gyro and accelerometer values from the MPU6050 sensor.
As a base start I downloaded the NRF5 SDK V15.3.0 and modified twi_sensor_pca10056 program...
Hi. I'm using nRF52832, SDK13.0.0.
I should use SHA256 and MD5.
I made my code as below.
NRF_CRYPTO_HASH_CREATE(init_packet_hash, SHA256); NRF_CRYPTO_HASH_CREATE(init_packet_md5...
Hi. I'm using nRF52832, SDK13.0.0.
I want to use SHA256 as below.
output32Byte = SHA256[input32Byte];
Which function or example can I refer to?
And also I want to...
I tried to port the example "ble_app_ipsp_initiator" to pc-ble-driver and run on Linux. The peer device is another PCA10056 device running ble_app_ipsp_acceptor. The problem...
hi...
i want to use two uarts in nRF52840 , one uart to one pc and another uart to another pc .Data should be transferred and received between the nRF52840 and pc how can...
Hi,
for my sound application, I want to get the amplitude, or dB, of the PDM samples.
Are there any existing function implemented? If not, how can I code it on my own...
Hi, I just started using the nRF52 dev. kit. I am trying to familiarize with the BLE examples.
I have downloaded the nRF Connect...and I can detect the device.
The SDK...
Hi,
I added one more timer. As soon as the timer expires and it runs the event handler, and then advertising stops, and the firmware crashes.
Could someone please tell...
I've recently discovered the power consumption issue with FreeRTOS and SDK12.3:
devzone.nordicsemi.com/.../
So, I am now using SDK12.3 with SDK13.1 FreeRTOS files.

I am using Nordic SDK to program an nRF51822 chip. I want to optimize power consumption as much as possible so I am looking at using the -march gcc flag. The problem is I...
I am using the ble_peripheral template that comes in Nordic SDK 8.1. I setup uart logging and also debugging with the following lines of code:
void assert_nrf_callback...
Hi, We are trying to connect a LED to one of the GPIO of nRF52840, we would like to know how to connect it. Connect it such that the nRF52 GPIO sink current or source current...
Hey, I am using WT51822-S4AT module and want the nrf51822 to connect to phone. I don't have nrf51-dk. I am using stm32f0-discovery kit. Can it be done using that kit? I searched...
Seems battery reads are not consistent in thngy52 2.1.0 software.
Observed a ~4% difference in the consequent battery reads. This difference is high (upto ~40%) if the thingy...
In the recent past, I used a SoC in which GPIOs could be configured as "open drain", that is in which there is an internal transistor where the SOURCE is grounded, the DRAIN...
Hey,
I'm using nRF as a SPI slave with a Raspberry Pi. I'm seeing that even at ~3MHz SPI frequency, my first byte transferred gets corrupted. I have a test setup where...
I am using nrf52 with s132 and armgcc
As I add functionality to the code I get to a stage where it fails. Linker runs OK but the result fails to execute.
The observable...
