Hi,
I'm interfacing a nrf51822 and a H8/3294. My question is how much can I drain a the txd pin of the H8/3294. That means my question isn't really about nrf51822.
In documentation...
Hi,
On the 3.30 of nRF52832_Rev_1_Errata_v1.5.pdf, the sleep current with LFXO active is 0.5μA higher.
I am using a nRF52832 module with the low frequency crystal oscillator...
Hi,
I'm using nRF52832 on SDK V12.2. I add the connection params in the conn_params_init:
static void conn_params_init(void){
uint32_t err_code;
ble_conn_params_init_t...
S130, SDK 12.3, ble_app_hrs_c example.
I want to use whitelist function in this example but I can't finish it.
When I run peer_list_get(), it gets all 0xFF, means that...
Hi all,
I am making a device which involves using nfr52832(PCA10040) to communicate with a NAND flash through spi to store data acquired from the ADC. After all the data...
Is there any way that a BLE event handler installed with NRF_SDH_BLE_OBSERVER, can stop the execution of other (following) observers?
I have various modules using their...
Hi
I am a student and this is my first project working on BLE. Please keep that in mind.
The end goal is to create a fingerprinting system with a Thingy (nRF6936) as...
I have modified the BLE app Blinky example so that the LED is enabled (state 1) on power up. However, this is not being reflected on the BLE side because when I connect with...
Hi, when debugging, I'm encountering this problem where relevant SPI registers (likely status registers) signaled a successful read before the actual data could be pulled...
We're developing a mobile application which will communicate with a satellite antenna over BLE. We will not have access to the antenna for a few months, and therefore we aquired...
I am using the UART to perform serial DFU on nRF52832. I got it to work fine using nRF Connect SDK 1.8.0.
Now, I need to pass some serial data to the APP when not in DFU...
Hi, I have to develop a new nRF5340/Zephyr/MCUBoot-based device that communicates with a Windows application via USB. The Windows application already manages other legacy...
Hello,
I'm trying to implement a set up of the ble device name from the NVMC UICR register.
But when I try to take it from the register and to set it has a name, it doesn...
Hi,
when using the spi peripheral in slave configuration, what can I expect at power consumption level? does the spi peripheral derive its clock from an internal system...
Hello,
I am using nRF52840 DK's P20 SWD to communicate with an external nRF52840 board . My setup works fine with nrfjprog running from command line. To communicate with...
Is there any example code using a QSPI image as the input for the bootloader instead of e.g. BLE? What format does that have to be in to begin with? Currently doing DFU updates...
Hello friends
I am fresher for Nordic semiconductor . I want to interface triaxial accelerometer of 15MHZ frequency with nrf52840 with inbuilt ADC and transmit the data...
Hello,
I will try to use the macro ZB_ZCL_SET_MODIFY_ATTR_VALUE_CB to define a callback when an attribut is written in my device. But the callback I write is never called...
I had a look on APIs to use UART in Zephyr in the link https://docs.zephyrproject.org/latest/reference/peripherals/uart.html#uart-interrupt-api . There are three types: Poll...
I have a JDY-16 BLE chip in AT command mode and are able to scan for a SoftRF device that has a Nordic UART service.
I can succesfully see the SoftRF device during a scan...
