we also produced self PWM for ADC wave form testing. when we stop transmission, we will get good waveform out, but when we starting transmission, output waveform shape is...
Dear Support,
I have some troubles with the Evaluation Kit for nRF51822 :
I use the broad as a central role with S120_nrf51822_1.0.0_softdevice.hex and example...
Suppose a nRF9E5 transmitter is set for continuous transmission on a channel.
A nRF9E5 receiver listening on that channel:
finds carrier and sets CD
finds address...
I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...
I am try this at nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard

Hello,
can I change the message that appears in the notification bar of the beacon server lib for Android 5.x? I know how to do that. I would like to know if it is allowed...
Hi folks! First post here. Can anyone recommend an external amplifier (preferably preamp and PA, but just a PA will do) for the nRF905 for use at 900MHz?
Thanks,

Our system will awake from an external accelerometer interrupt, so I would need a code fragment which shuts down S110 soft device (and radio of course) and also all the nRF51822...
Hi,
I'm trying to test a new nrf51 board using the s130 softdevice and the ble_app_hrs_130 example. However, the program seems to hang in the ble_stack_init function (code...
I'm trying to implement DFU-OTA (Bluetooth transport) for our custom board and currently i'm facing problems in flashing the different elements (softdevice, bootloader, application...
I need to implement a PWM analyzer. I looked at the example in SDK 6 and it's fairly easy to follow. When I tried it, it doesn't look like GPIOTE handler gets called frequently...
I'm trying to backport the code form SDK 9.0 to SDK 7.2,
but i need to make sure that can be supported.
I found the "ATT-51", and there is a table about that,but the last...
ble_dtm.c has some bugs related to signed integer representation which prevent negative power (less than 0 dBm) from being requested in the vendor specific message.

Hi, all.
I'm using "SEGGER_RTT_printf" for debugging. Because have no uart port on my development board.
I want print double type variable like below.

I am currently trying to communicate with a GPS module using the UART on an nRF51422 (using the Dynastream N548M5CB module). I am using SDK v9.0.0 and the FIFO version of...
Hi,
I want to send a continuous stream of data very quickly into the nRF51 through SPI and then dispatching it to a smartphone via BLE.
However I keep getting BLE no...
Hello
When i am in keil uvision 5.18 and use the pack installer all the examples using Softdevice S110 are gone in Keil. Is this a known issue and is there any way to solve...
I followed the instructions and comments in devzone.nordicsemi.com/.../ . I built a project around the ble_app_gls example (with a couple of minor changes such as using -DNRF_LOG_USES_RTT...
Hi, I would like to program nRF51822 flash over SWD interface. I have another micro LPC1100 series that has the flash image for RF51822 and connected to nRF51822 over SWDIO...
