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...
Hello,
I am using nRF52840, SDK_16.0.0, SoftDevice S140 V7.0.1 and Segger for flashing the image. I am using ‘ble_app_blinky’.
I want to send packet with different...
Hi,
In our project we are using the adc pin (p02) for batttery level measurement.
The analog dc signal from the battery is connected to p02 pin after the voltage is...
Hello,
Our peripheral device has no keyboard and no display.
Yet we would still like to have the most secured way of communication.
For our application, we don't like...
Apologies for the newbie question. Does this BLE Module need a separate antenna to be purchased? Or are you supposed to design your own with PCB traces? Some BLE modules have...
I want to avoid the soldering of the inside (Becoz of production isse) pins that's why I'm using all the outer pins of the ic. But the problem is RESET pin is inside so can...
Hello,
I am using UART_1 in my program to comminicate with other sensor. So the data is read from UART_1 and print to UART_0. Now I want to communicate with other sensor...
Hi, I am using BMD301 chip on my custom board which schematic i have shown below,I need to enable UART as well as nrf_log in my application. For this I am using SDK 15.3 PCA10040...
I am getting small power spikes but cant seem to pinpoint what is causing them.
The smaller spikes in between the transmissions. (The wave is clipped from the top so the...
Hello,
Has there been any success with getting the python bindings for the pc-ble-driver running on openwrt? I've succeeded with the driver itself but not the bindings....
So with the errata in mind the RC oscillator has a accuracy of +/-500 ppm, while the XTAL on the nRF52 DK has a accuracy of +/-20 ppm. During the longest waiting period of...
I have your full eval board as well, I also have multiple NB_IoT sims from Vodafone but have not tried them yet. How do I get your Thingy:91 unit with your sim running please...
Hello,
I want to implement a data logger that will save events in an external flash (even if i think i will start with the FDS). My purpose is to identify some behavior...
Hello,
I am looking to start an independent project this month. One of the tasks will be to use BLE to relay information from a custom PCB board with the nRF52810 chip...
