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...

An...
I have set up the NCS toolchain, followed the instructions to update the JLink DLL in SES, and successfully built/flashed a few examples to the app core (ie. debug/ppi_trace...
I would like to send TCP message with 50KB message size. I saw that maximum size was limited by CONFIG_HEAP_MEM_POOL_SIZE which was 16kB.
Is there any way to send that message...
Hi,
we are experiencing unexpected behavior during sleep entry. Following pictures were taken using an oscilloscope, our device sends a radio transmission every 150 ms...
Hello,
I am trying to sample and reconstruct an audio signal using the SAADC and I2S respectively. I have a double buffer setup for the SAADC, where we process the data...
Hi,
I've noticed several times now when the NRF9160 comes out of a PSM sleep cycle that when a call to an underlying socket connect(), or nrf_getaddrinfo() call (whether...
HI,
I am developing an application with 7 transmitters and 1 receivers. Transmitter are nrf52832 with MPU9250 IMU (Holyiot YJ-18008) . I am hopping to each transmitter...
I successfully compiled and loaded the UART/Serial Port Emulation over BLE example on an AdaFruit Feather board.
I can connect to the Nordic UART Service, then send data...
I have built my application on ble_app_uart in keil in SDK 14, so I just did the same and copy-pasted my code into the latest ble_app_uart example built with ses in SDK 16...
So far i've failed to find a single source that contains comprehensive information on where errata items have been addressed. I do have multiple unrelated sources for information...
Hello, I want to try the secure bootloader + softdevice 7.0.1 + ble app buttonless dfu example from SDK16 I want to test all that in our custom board NRF52832-QFAB (256k flash...
Hello, I modified the ble_app_blinky example to work on our board (removed leds and buttons) and modified the board pca10040.h the new application worked on the devkit but...
Hello, I am completely new to embedded software development (so far I have been using development boards such as Teensy, Feather and Arduino) and I recently acquired the BLYST...
Hi
I'm currently look into the noise floor of the SAADC samples on a custom PCB with a nRF52
I'm running the ADC at maximum sensitivity (4x gain, Vref=0.6V) differential...
Hello
I have a power constraint device. Limit is not the total charge of a battery or so. Limit is the peak current.
Available (peak) current is around 4mA (@1.8V), current...
Hi,all. i face a problem that i used lightblue on iphone6(ios8.3 12F70) to connect my device(nRF51822),after sometime,disconnected automatic.
