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
Firt I connect to Android device and keep one whitelist.pp_addrs and one whitelist...
Hi, I have two device. S120 Scanner and S110 Peripheral Device.
At Scanner, I use SDK 9.0.0 and S130 1.0.0, At Peripheral Device, I use SDK 9.0.0 and S110 8.0.0 ..

hello,
I have a custom board which works fine with SoftDevice+Application , but if i Combine a boot loader hex that i complied it doesn't work. But the same ( bootloader...
I found and implemented an example that gives me a decent idea of how to go about polling for data with the UART/FIFO. However this doesn't give any indication of how to use...
Hi.
Trying to set up the Ubuntu development environment for you nRF52 development kit.
I followed this tutorial:
devzone.nordicsemi.com/.../
Stuff done so far:...
I am using the nRF51822 chip. The RAM memory is composed of two blocks (0 and 1) of 8kB each, divided into 4 sections : Call Stack, Heap, Application, and SoftDevice.
If...
Hello,
I have migrated to the latest version of the sdk11. However, I get a nrf error 4 when I call sd_ble_uuid_vs_add. Multiple people on this site have been having this...
I am trying to port blinky_blank (no SoftDevice) to my target and started by creating a custom_board.h header file with correct GPIO pins for the LEDs and duplicating blinky_blank_pca10040...
Can anyone help me reading IO capability in Android? Basically there is a known bug in some Android versions across different manufactures where Android reports wrongly IO...
I want to use chacha20 cypher to encrypt and decrypt a 64 byte message and send it over BLE. I tried using wolfSSL, cifra both of which provides the implementations but there...
Hi,
To measure the transmitted RF power (to reach EN 300 328) we Need some ATT commands to set fix channel and maximal output power. In additional we test the EN 55022...
In this previous discussion on minimizing power consumption on the NRF51-Dongle, it says:
You are using evaluation kit or
development kit and LEDs are connected

My system is a BLE peripheral with 2 states. There is a characteristic that represents the state, and it can take 2 values: 0 and 1.
You can read the state, write it (force...
When the supply voltage drops below 0.6V and then get back to 3.3V the nrf51822 starts up in an undefined state and often some flash pages are corrupt after that. Is this...
