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...
The S130 SD supports up to 3 concurrent central connections. Once it has made the maximum number of connections can it still scan for non-connecting peripherals, e.g. to look...
I have 2 PWMs working with the version 8 softdevice on an nRF51422, and it's straightforward enough to change the duty cycle with app_pwm_channel_duty_set() in the app_pwm...
The way of entering the bootloader mode is sending the command,then run the code as follows:
void jump_to_bootloader(void)
{
uint8_t softdevice_enabled;
uint32_t err_code;...
I'm sorry but i don't know where else to turn. The tutorial on adding a characteristic to a service (the nordic tutorial i am basing this off) isn't finished and I have no...
Hi
I did not quit yet understand the Gazell Pairing library.
If an encrypted message is send, how do I add some payload to the acknowledgement.
And how will I be able...
Hi,when i set NRF_RADIO->MODE in RADIO_MODE_MODE_Nrf_1Mbit ,then use radio_tx_carrier(txpower_, mode_, CH_LOW); i got a picture with spectrum analyzer like this ! , when i...
Hi
I have been using the double buffer DFU for a while now, and it works reliably for me.
However, I am hitting the application size limit that can be handled by the double...
Hi,
We developed the app using the nRF Beacon App sample code.
I want to ask for a good application notes or some hints which I can use for developing.
* Is the API documentation...
The nRF51822 Product Specification says that "Maximum number of pins with 5 mA high drive is 3."
Does that mean that you can only configure 3 pins as high drive, or could...
I managed to upload my application OTA DFU when there was only the bootloader running. After my application is there, I can start DFU and my application runs thru reset_prepare...
Is there a firmware locking feature for either 51422/51822, or can you purchase OTP (one time programmable) versions?
Can you buy them mask programmed from Nordic?
I...
I want to get sensor data from arduino, with atleast 200 samples per second, but at present I am only getting around 20 samples per second. I went through forums and got to...
