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;

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...
Does anyone know how the raw data message is structured to enable GATT Proxy? Here is a screenshot from the app. I know one byte is used to indicate whether to enable or disable...
Hi,
actually I developed a system based on an nRF24AP2 able to read data coming from different HRM ANT+ sensors and transmit them via WiFi using ESP8266 that is acting as...
I have clock drift issue, should I calibrate anything? I test this simple code to get 1second or 100ms signal both of them are inaccurate.
here is my code for 100ms; I tested...
I'm trying a new device based upon the nrf52810 and it won't run past sd_softdevice_enable - it goes to the assembler window and halts. The device does have a 32kHz xtal and...
Hello,
I was reading some SDK 15.3 code, there's something like this:
__STATIC_INLINE void pwr_mgmt_sleep_init(void) { #ifdef SOFTDEVICE_PRESENT ASSERT(current_int_priority_get...
Hi all, I'm developing nRF52840-DK to use it as an central device.
Base example is usbd_ble_uart: I'm going to communicate with peripheral device using BLE, and control...
We have a product that uses the nRF52840. We have seen that very rarely, unexpected resets happen with the reason being OFF. We have yet to encounter this issue in a lab setting...
I'm using the SPI manager to talk to an ILI9342 graphics IC. I need to toggle an IO line during a transaction or in between transfers. For the first byte the line will be...
I am trying to enable DFU over USB with the nRF52480, while keeping the possibility for Serial communication. I got a working example with both separate, however when I try...
It's my mistakes.
1.I want to measure temperature from DS18B20,but I don't confirm the capable of the pin - P0.05.Because it's Analog ，but DS18B20 is Digital.
2.I set the...
Hello, I'm getting started with a nRF52832, I've got the SDK 16.0 installed and what I think are all the latest packs installed. I try to build the examples\ble_peripheral...

When my program starts, I set up a watchdog timer for 100 milliseconds and I start a repeated app timer that runs every 90 milliseconds to feed the watchdog. I use the app...
I'm trying to send data via UART from a NUCLEO-F401RE to the nRF 52840 DK. But the data I send is not comming through correctly. For example when I send 3 the nRF prints 32...
I have an existing product to which I need to add SPI to get Wifi compatibility. Basically the Nrf52 is acting as central and passes BLE events on to an ESP32 with Arduino...
