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'm trying to use the nRF COMP peripheral in Zephyr. My application boots and runs normally until I enable the DeviceTree overlay for the COMP. As soon as the overlay...
Hello,
What will happen if I try to change the device's TX power using the vendor-specific command SDC_HCI_OPCODE_CMD_VS_ZEPHYR_WRITE_TX_POWER while LE Power Control feature...
hi,
I use nrf54l15dk with ncs-v3.1.0, the project is based sample "central_hids";
The purpose is I want to change console uart from "pin1.04/pin1.05<uart20>" to "pin2...
I’m developing a project on the nRF52840 that uses BLE + RTC + an SD card. It’s based on a previous project that only used BLE + RTC, and I’ve added the ability to store data...
I'm trying to use a Power Profiler Kit II with a Mac running Ventura 13.7.8. If I update the Power Profiler App to v4.3.0 or v4.3.1 the PPK II is not detected and this is...
Dear Team,
I am using NRF54L15 DK, where I have UART defined and mapped as following:
uart20_default: uart20_default {
group1 {
psels = <NRF_PSEL(UART_TX, 1 ,...
I'm struggling to obtain stable ADC readings on the nRF54L15, and I'd appreciate any suggestions. I have the ADC configured with gain = 1, internal reference, 10 bit resolution...
Hello,
I'm trying to get a TIMER triggered ADC read on P1.11 AIN4. Sample advanced_non_blocking_internal_timer sounds like what I want but it isn't NRF54L15 compatible...
I am designing a very-low-cost device based on the nRF9151 and would like a quick technical clarification.
My plan is to power the SoC and all GPIO rails from a single 3...
I'm working on a project were we require the use of a custom OOB key (not generated by the device itself) and LESC.
We have both the central and peripheral device to configure...
Hi ,
Our nRF52840 chip is drawing a high-current burst of about 1.5 seconds during the DFU upgrade. Because we have a 10 mA current limit on the battery, the system browns...
