Hi,
We designed the circuit followed the reference circuit(QFN48), but we always failed in the 8kv ESD test.The CPU always reset while ESD testing.
The 8kv ESD power...
Does anybody got an app inventor2 "project" to communicate with the (Adafruit) Bluefruit LE UART (or SPI) ?
Note: my Android version is 4.4.2 (LE "advertising" not supported...
I've created a Secure DFU client using the multilink central example with S130 and SDK 12.2 (running on PCA10031).
There are a few issues we have trouble with.
The...
Hi,
After successfully managing to preserve our devices bonding information (and custom app context data) across DFU updates, we have a few related questions.
I should...
I would appreciate some suggestions on a good development flow to go from an Example to end application
I have nrf52832 on a custom PCB.
I tested several sdk13.0.0 examples...
If anyone will ever have this error:
When using c++ and singleton the use of operator new is not possible.
I found the solution in this post: forum.arduino.cc/index.php...
I'm using 3.6v battery and I want to read the battery voltage, can I get the power ping directly to the any ADC pin of nrf52833 ? Or it cause any damage to the ic ?
Hi,
In the attached study from Nordic and Energizer there is data regarding the discharge behavior of a CR2032 Coincell battery under different conditions. I wanted to...
We are using nRF9160 as the host MCU and Modem for communicating to server. If VDD_GPIO is powered by 3V external supply and SIM card is powered by VDD_SIM i.e. 1.8V Do we...
Hi,
I have a hex file generated by uVision Keil 5 IDE . I would like to combine this with the hex file form the soft device. These two hex files once combined would help...
Hi,
I would like to change the manufacturing data with time. My advertising_init function implements the following line
init.advdata.p_manuf_specific_data = &manuf_data_response;...
I've been using the nRF52840 DK to load the firmware into my custom nRF52840 board using nRF Connect v2.6.0 and programmer v1.0.2.
However, on another laptop when I install...
Hi,
We have developed a custom board using nrf52832 chip and currently everything like (BLE, TWI, ADC etc) is working fine but we are having issues with the UART. we have...
Hi,
We are using nRF52840 with nRF5 SDK ver 16.0.0 with Softdevice S113 ver 7.0.1.
We use the radio timeslot to implement low level radio comm with very tight timing requirements...
hi i am using this to capture the adc value data_ADC=adc_buffer[1]*(1024+gain_error) / 1024 + offset_error - 0.5; data_ADC_double=data_ADC*3.6/1024; MULTIMETER MEASUREMENT...
When I used nrF52832 mouse application, the SDK version was 15.3. When I connected to MacOS, I had to make several attempts to connect. Can you tell me why?
Thank you very...
Our nRF52832-based board is powered by a coin cell battery, and spikes in current can cause the voltage to drop. This is okay early in the battery's discharge curve, but as...
The communication between the UART peripheral and the nrf52840 works fine until some device connects to the nrf device via BLE. Using a digital logic analyzer I'm able to...
hello
now we want to use nrf52840 qspi interface to connect with fpga. we have a question:whether nrf52840 could be used as qspi slave, and fpga used as master?
if it...
