I have been running a mqttsn client publisher/subscriber project (based on the example) successfully for some months. I have added a mosquitto broker to the raspberry pi border...
We are designing BLE products based on the Nordic nRF52840 chipset and star network topology which are used indoors, according to the network structure, we use one Master...
Hi everyone!
I've been using the Power Profiler Kit quite successfully for the past few months. Instead of using the UI, I designed a python app to communicate with it ...
The nRF52840 OPS 0.5.1, describes nWRITE,BLOCK as the amount of writes allowed in a block between erases, and lists nWRITE,BLOCK = 403 Maximum.
It looks like 8 blocks are...
Hi folks,
I have a system basically working with the following setup:
#define MIN_CONN_INTERVAL MSEC_TO_UNITS(7.5, UNIT_1_25_MS) #define MAX_CONN_INTERVAL MSEC_TO_UNITS...
adv interval : 1s
adv data: 31byte
tx power: 0dBm
MCU: nRF52832
The power consumption is shown in the figure below,when I don't enable DCDC.
what may be the reason...
I followed all the steps mentioned in the tutorials. In one of the threads, it was mentioned to erase all and then try and it worked for some. I tried that as well. Still...
I'm using nRF Connect v2.6.2 on windows 10 using an nRF51 dongle to update my target OTA. Target is an nRF52832, softdevice s132 v6,1,1. The DFU process takes like forever...
Hello,
I work in a startup, and we aim to measure cooling conditions in data centers.
For that, we have developed customs boards with a nRF52840, and we are using Bluetooth...
Hi, I am currently using Nordic nRF52 dev board (with nRF52832 SoC) and trying to test "dfu/secure_bootloader" example in that board. Because my target ship is nRF52810 I...
Hi,
We would like to activate the "legacy" 4G DRX with a period of 1.28s. Do you confirm that the needed AT command is: AT+CEDRXS=1,4,"0000" ?
