I'm trying to solve an intermittent problem when using the nRF51422 UART with CMSIS-RTOS (RTX) and MDK Networking library (V6.2) (TCP/IP stack).
My questions relate to...
Hi...
When i was working in SDK v6.1.0 i have tried nrfprog.exe to merge and program bootloader, softdevice, application and bootloader_settings file as explained in devzone...
But now I have a new problem that is whenever I set " PWR_UP " bit in CONFIG register then it drop the 3.3 volt vcc to 1.2 volt. I don't know why its happening. Anyway, is...
This previous question about multiple advertisements seems to be related to softdevice 7. I was unable to get a similar example working in SD/SDK8
My end-goal is to add...
We are considering using Gazell for an outdoor application, i.e. lots of noise and disturbances, constantly changing environment, where the amount data being transferred is...
Hello,
Happy New Year.
I'm not able to find nRF52840-QIAA-T or any replacement of this SoC available in the North American market.
I need atleast 5 SoC of the...
Setup: nrf52840 (without internal dc/dc), VDD = 3.3V
Assuming the VDD rail ramps up slowly, the nrf52 will start booting at it's power-on reset threshold of 1.75V (POR)...
Dear BLE Experts, I've followed this tutorial to create a custom GATT service and characteristic. The tutorial seems to be based on the BLE SDK , not the MESH sdk, hence the...
Hello,
Our company is kicking off a project (while we are at the very beginning stage) where multiple nodes (up to 1K) should be connected within a mutual network. I wanted...
We are looking to increase battery life for a product that uses the nRF52832. I'm wondering if it's possible to provide 1.3V directly to the DEC4 pin rather than use the internal...
Hi, I'm referring to this post over 3 years ago: Nordic DevZone (nordicsemi.com)
I'm using Android 8.0, and I'm using SDK 12.3.0 for firmware. I'm trying to create bond...
Hi,
I noticed that when I initiate a chip-erase on the flash-chip and reset the MCU, I'm getting NRFX_ERROR_TIMEOUT's on my nrfx_qspi_init().
I found this ticket: https...
i am using nrf52840 DK with softdevice (s140_nrf52840_5.0.0-1.alpha_softdevice) and applying this throughput example ATT_MTU Throughput Example . and notice that when I use...
Hello I have a problem with the scanning of ble phy coded in Android, I need it to be continuous (or almost) but it seems that for coded it is not possible unlike with legacy...
There are more than one task, after completing the periodic work,the 52832 module should enter system on low power mode,sleep 30 minutes,then wake up and continue with the...
Hello:
I have set the scanning module to search devices by MAC address. It finds the devices that are using a Static Random address, but it cannot find the ones using a...
Hi,
in my project I have a custom board with a nRF52832 chip that reads SAADC data and transmits this data (peripheral role). This data is received by a nRF52840-DK board...
I have an application that is running on using nRF52840 and FreeRTOS. I am considering transitioning to nRF5340. For now, it appears that this also means transitioning from...
Hi,
I am exploring the feasibility of building a firmware for nRF52840 that supports both BLE Mesh as well as ZigBee stack (in the same firmware) but only require one of...
