I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
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...
Hi,
We are using nRF51822 chip, and we are using TL3315 switches. I am very new to dealing with buttons. The current problem is that when I press the button, the MCU seems...
Hi,
I would like to flash a CC3100MOD wifi chip from TI with the Nordic 52832 chip as a host. Attached is my schematic. I am fairly new to the nordic family but I have...
Hi,
The problem statement mentioned below.
What we are trying to do is Read Light value from the MAX44009 sensor on the TWI interface.
Looking at the data sheet for...
Hi,
I am using Nordic nRF52840 SoC with nRF5_SDK_15.2.0_9412b96 (SDK) and S140 softdevice. I tried to set Tx power to +8dbm using
rc = sd_ble_gap_tx_power_set (BLE_GAP_TX_POWER_ROLE_ADV...
I am currently involved in developing a product that is using the nrf52840. The product needs to keep precise time across a wide range of temperatures, which is why a 32Mhz...
Hi,
When I try spi commnucation with sensor on nrf52840 (using Mbed OS with SDK14.2), it stuck to nrf_spim_task_trigger (p_spim, NRF_SPIM_TASK_START); while spim_xfer is...
Hi,
I am trying to increase the sampling rate of the motion sensor on a Thingy:52. I managed to update the firmware and increase the BLE_GAP_ADV_INTERVAL_MAX from 200 to...
I am using softdevice s132, nRF52832 and SDK 15.3
This happens every time I connect the RX line.
This is an application where I implement UART with the HRS application...
Hi,
I am interested to know how to make a mesh node (for example, a light server) compatible to perform a DFU.
I have gone through the DFU page and I noticed that the...
Hello.
I am about to receive the Uart service for the Nordic SDK Central and peripheral.
I Use nrf 52832.
In the peripheral example, we used 'ble_nus_data_send'...
Hi,
I am using nRF52840 Enineering C chip on a custom board using SDK v15.3.0 with SoftDevice v6.1.1
I have modified the Blinky Central code and the Blinky Peripheral...
Hi. After my nRF52832 peripheral connects to an android / iOS, I am trying to read the MTU size that has been negotiated with the following code;
current_mtu is being...
The NVMC writting functions hasn't return values,
void nrf_nvmc_write_bytes(uint32_t address, const uint8_t * src, uint32_t num_bytes)
Does it mean that all internal...
When nRF52840 P0.09 / P0.10 are used as GPIOs, the datasheet indicates they can be used for "low frequency I/O only". What is the frequency limit on these pins? Would it be...
