Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi,
I want to increase the amount of BLE MIDI packages I am sending. Softdevice 132 nrf52832
MIDI data is sent by notifications and updates of the characteristic value...
Hi,
I want to use uart async on the nrf9160, I get the following linking errors at build time:
here is my prj.conf
If it's defined CONFIG_UART_INTERRUPT_DRIVEN...
Hello,
I have a question regarding the nRF5340 microcontroller or similar. Usually, when programming UART, I2C or SPI bare metal, one is using interrupts, register and buffers...
Hi Team,
We are working on project where we are trying to encrypt the advertisement data (non-connectable) using our own defined keys.
currently I have been through the...
Using Segger with PCA10056 as a debugger connected to a pcb with a NRF52840 on it. Been working fine and I tried building open bootloader and programmed it. I see the device...
Hello,
I am a newby to the nRF5340 and Zephyr and I am stuck. I would like to know how to map physical pins to a particular UARTE.
I have read in the user manual OPS_v0...
Hello,
Currently developing a system based around the NRF9160 running Zephyr. My application is threaded and i would like to run the thread_analyzer. I got this working...
Hello,
I want to hide the BLE(RF signals) completely soon after updating the configuration in my application and whenever I need to update the config I should be able to...
Hi, I'm reading an ADC channel connected to large capacitors. I do the read when charging is off so no ripple. The caps are large (super-caps) so hold well enough to show...
Hey. If the device is repeatedly flashed without turning off its power (it does not matter if I program it through SES or nRFgo), it may start to malfunction or slow down...
Hello
I would like to use three PWM to output multiple sounds with one buzzer.
First of all, I am testing using two PWM. There is no problem using only one PWM, but there...
Hi, I'm currently using TAIYO YUDEN's EYSLCNZWW (nRF52810) and We are developing a device like a pulse oximeter.
I would like to change SAADC_SAMPLE_RATE from 400ms to 100ms...
Hi, after using the nRF SDK examples with SES for some time now, I decided to go with a project from scratch but for some strange reason the directory where I keep the nRF...
