I'm using S332 0.9.1 with freertos. nRF52.
BLE and ANT are both active. I would like to run the ANT continuos wave (CW) test after a specific trigger (a command over a console...
I want to encrypt advertisements using aes-ccm peripheral present on the nrf51 board. I am not using softdevice, instead I am generating my own packets and transmitting them...
Currently, it using the I2S at nRF52832.
I want to play the wave file,But can not play well.
So, I ask you for a check because there is the following question.

We love the radio range of the Nordic bluetooth chips. I am looking to see if anyone is developing a long-range bluetooth pendant or wearable? if so, I interested in perhaps...
I'm trying to read 8 adc channels using SPI, but then if I dont put some nrf_delay_ms the MISO return nothing and the CS is being driven low by default, high or a period of...
Does rbc_mesh_value_enable() API is designed for ? and how should I use it? and what does its parameter handle mean? Is it has the same meanning as the parameter handle of...
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...
