I'm looking into a rare issue on the BBC micro:bit V2 which uses the nRF52833 as its (application) microcontroller. I used to be familiar with some CPUs from the 80s but my...
Hi,
I have an idea to implement BLE based access control application. I considered nRF51822 based Peripheral device & iOS application for central device
Both the Central...
We are in the process of creating our 2nd pass boards with following components to achieve good RF range>20 meters. We are considering discrete BALUN components and SMD Chip...
I see 5V pins on the schematic for the new nRF51 development kit. If I power the board via USB, I understand that 5V is regulated down to 3.3V for the chip. Is the source...
hi,
i'm gonna make 51822 enter low power consumption mode.Meanwhile it could be wake up by "GPIOTE_IRQHandler()"

Hello dear Nordic community,
currently I am working on the NRF51822 Direct test mode (DTM). I tested the ble_app_dtm example and it works fine for me.
This means I can...
Hi,
I bought nRF51822 Evaluation Kit and would like to blue wire an external MCU( Kinetis Cortex-M) to talk to the SoC. It looks like the SoC on this board has many GPIOs...
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...
