Hi, Any one kindly suggest and Chip based antenna for the Thread + BLE and Wi-Fi + BLE protocol in NRF54L15 protocol. Also kindly suggest the PCB based antenna for the Thread...
Hi,
We are currently in the research and development phase for a new line of IoT devices designed to work over the Matter protocol. After thorough evaluation, we found the...
Hi,
I started the LBS example on the nRF52DK_52832 kit and connected the PPK2 kit to the P22 pins for measuring power consumption. I am not sure if I did something wrong...
Hello forum ,
As i m working in nordic nrf52840 where i have taken adc value of photodiode ,then i have created service and characteristics i will share the image for that...
Hi,
Does Central or Peripheral UART enable ACK/NACK in the code for BLE communication? How does Peripheral recognize if Central has received all the data ? Is there any...
Hi
I had a device that did not start up - because it was waiting for the 32KHz clock to be stable.
So I tried to change the setting below from 15pF to 5pF and it started...
Hi,
Could someone can explain, how to handle Static Passkey in iOS Central application?
I would like to know whether iOS application allows static key based pairing or not...
Hello,
i'm programming an iOS app to connect to the nRF51822 (peripheral). The Problem: Any kind of authentication and encryption is needed, but in the final Product the...
I've seeing random crashes at that originate from ll_lm.s0.c:404. It seems to be happening when I have uart logging turned off. I don't think i've seen assert callback called...
Says it all in the title. I'm making a sensor which puts its data in a non-directed non-connectable advertisment packet. I want to read the sensor just before it is sent....
Hi,
We are designing our 2nd pass design based on nRF51822 this would be our production version PCB.
We would like to have our Schematics,Layout and BoM reviewed from your...
Hi,
I am using softdevice-7 and SDK 6.1 for our application. I want to implement static key pairing for serial port over ble application "ble_app_uart".
I have implemented...
I have a 384 byte, writable, variable length, vloc user characteristic and I want to trigger an event when the write completes so my application can operate on the data. ...
Hello-
I am trying to program a custom nRF51822 board with a J-Link-lite.
From the J-Link-lite, I am using the 10-pin header and have it wired like this:
I'm using pins...
I have a situation where I need a software PWM for several channels, which are multiplexed via a shift register.
The output loop needs to run at several kHz for this to...
Because of the limitation in the GPIOTE hardware that only one channel can be connected per GPIO , care must be taken when changing a PWM duty cycle. If for instance the compare...

Hi Nordic
I do not know why sometimes program can build pass in keil ,but can make nrf51822 do not work and unable download program . For this , I have damaged a lot of...
Does the nrf51822 support 2 spi masters (on different pins)? I want 1 spi channel to talk to one set of peripherals, and the other to talk to another set. I see SPI_MASTER1_ENABLE...
