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

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...
Hello team,
Is there a standard Nordic policy for longevity of SoftDevice updates and continued support for a device once it has been deemed "mature"? Context: I'm beginning...
Hi,
My nrf 52840 pdk and my custom pcb with nrf 52840 soc. both are running with same application ble_proximity example from sdk 14.1 and softdevice s140 5.0. when i set...
Hello All,
Chip : nrf52832
Mobile App : BLE scanner
Requirement : We want to transfer 20 Bytes(or more) at every 8 ms. Is it possible?
I have tested it :
No of Bytes...
Hi all i am facing few problem after checking the power consumption of the nRF52832 using the Power profiler kit. I followed the demo video in the link ( https://www.nordicsemi...
Could you please check whether 52840 can support memory map to QSPI PSRAM on QSPI interface?
If yes, that means the compiler would see a big RAM space of 2~8MB QSPI PSRAM...

If the register setting are different, can rx device recieve the message from tx device? whether...
Hi,
I use the peripheral ble_app_uart with nRF52832 (Murata module). The nRF52832 is connected to another MCU, STM32L476, via UART.
I develop using IAR, with SDK V15.0...
Hi All,
Enter to Direct Test Mode, the nRF52832 will transmit 2426MHz channel frequnicy only when set any different frequency channels (e.g. 2402MHz, 2418MHz) in the Tx...
Hello,
I don't understand why the ble_advdata_short_name_find function never return a true value. I'm sure that I send a short name because I verified this on the nRF connect...
Hello, I want to synchronize several peripherals with a central, I already tried to do it with the state of the gpiote but I did not have the expected result at the level...
Hi
I'm facing a Hard fault on the softdevice when trying to call sd_ble_gattc_write(). SDK15, SD140
I have a Multilink central connected to UART using app_uart. when a...
I have been doing a bit of searching and reading but I'm none the wiser.
I have a client that uses lots of BLE nRF51822 based modules made by Raytac Corporation in a classroom...
I am converting Arduino BNO080 library ( github.com/.../SparkFun_BNO080_Arduino_Library) to nRF52832.
Specifically, this is a function for sending a SHTP packet over I2C...
hi to all,
i had developed a device with NRF51822 wih S130 and i want to port my application to new NRF52840 soc S140 and SDK15, S130 has an structure that let me to limit...
Below are the symptoms, but it turns out the problem was quite simple: the device is not seem capable of scanning while at the same time being connected, unless you use a...
