Seeing recent response to my original question on multiple chip selects, I've opted to share a modification to spi_master that I've implemented in part to make handling some...
What is the official status of the Softdevice Serialization for S130 in SDK 9? I could see an older answer on how that was removed in SDK 8 but since almost half year has...
Hi
The documentation for the new feature in S110 v8 to change the gatt table size says that to change it the linker configuration needs changing .
This means it is a...
I used to be able to see my development kit in nRFgo studio and flashed S110 onto the chip. Now all I see is: "No boards connected". I am still able to flash programs onto...
Hello,
I have an iOS application communicating with a custom device having a nordic 8001 chip.
They have established a bonded relation. In nRFgo Studio, in Security...
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...
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...
