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...
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...
Hello I am using sdk v17.0 and nRF52DK.
I'm going to simply read the analog sensor MICS-5524 (gas sensor). And to do this, we used the SAADC example code and connected it...
I want to write a piece of big data to flash. Every time I write 112 word length, I write it many times. Every time I write, the address is shifted back 112. Before I write...
