Previously, I designed a PCB for the nRF52832 chip using the RFANT3216120A5T antenna ( link ). However, I was only able to achieve a very limited Bluetooth range of around...
Hi, I'm relatively new to Nordic microcontrollers and have recently completed the beginner's course. Sorry in advance if I made an obvious mistake.
I am currently trying...
We are running a nrf54l15 board that uses an NFC T2T tag to encode a URI to open an application. We have noticed that sometimes, the current stays higher (~200 uA) after the...
I’ve got a bit of a hardware issue with the nRF52811 UART, receiving DMX data from a Chinese DMX controller.
Standard DMX data-rate is 250Kb/S, so the minimum bit time is...

Hi!
I'm trying to configure my NRF8001 module with the help of nRFgo studio. I'm using Nordic UART over BTLE service template. The module can be discovered via nRF Master...
I am developing a power aware TWI driver for 51822/422. All appears to work properly except when I simulate a bus fault by shorting SCL to ground or shorting SCL and SDA together...
Hi,
Firstly a warning I'm a noob in this area.
I'm seeing some strange events consistently returned from the nRF8001 over SPI. I have an example of the SPI traffic below...
Hi! I would like to get adc sample from two different channels at the same time on my beacon (nrf1822), using the same interrupt. Is that possible?I mean I can use ADC_IRQhandler...
Hi,
It's a very simple question, is there a simple way to check GPIO pin status. I just want to know at a given time if the Pin is High/Low. I don't think I need an ISR...
Hi, I just started working on nRF52 with Bluetooth, and I have some concerns about DFU and security.
I’m working on a product equipped with an nRF52 and a MEMS microphone...
Hi!
I am using the NUS service and I noticed that Android 6 (Marshmallow) will not go faster that 47.5 ms. Even iOS can go to 30ms. My target is 7.5.
Am I doing something...
