I am trying to make a product with NRF8002B. I finally have the product prototyped. The user will connect to the device, beep, light up, and track. It will always stay on...
Please,
It seems that "Flow Control" signal is not available on nRF24AP2-USB.
EVENT_TRANSFER_TX_START event message appears only one time after the first data packets...
I am looking for cheapest (up to few hundred USD) and simplest Arduino basic solution to track real-time RFID tags distance (also direction if possible) without additional...
Hi all,
I am new to Nordic semiconductor but I could be interessed by nRF9E5. To check if it could fit my requierement, I would like to know if it possible to configure...
Hi,
I am using ADC without external reference and no analog input in order to measure the battery level with a timer (code at the end).
I am also reading several ports...
I'm currently trying to merge the S120 softdevice with the compiled code from the ble_app_multilink_central sample under Linux (Ubuntu).
Here is the command I'm executing...
There are a couple problems with the SDK 7.1.0 implementation of nrf_delay_us for GCC. The experiments I've run show the provided version generates delays 40-50% too long...
Hi,
I am developing an application to capture data on a PC over ANT+ using the ANTUSB-m as slave and the nRF51 DK as master.
In order to test my program I want to be able...
I had the same experience as fishman and I went back to give Eclipse a try. (Post: nRF Beacon does not build on Android studio) I tried to build it in Eclipse Luna with the...
I am trying to use the nrf51822 to send media button commands over HID. I have seen several questions on here and they usually involve the HID Mouse example (which doesn't...
Hello,
I have been trying to implement AES in order to encrypt a time stamtamp to be sent in the advert of the iBeacon ( 128 bits, using Minor and Major bits, (16+16)*4...
Hi,
I am trying to decrease circuit power consumption that's why I am using sd_ble_gap_tx_power_set(TX_POWER_LEVEL) function. When I set TX_POWER_LEVEL as 4 or -20, I dont...
We are looking to change tx_power setting to Neg30 dBm and for this we have accessed NRF_RADIO->TXPOWER = (RADIO_TXPOWER_TXPOWER_Neg30dBm << RADIO_TXPOWER_TXPOWER_Pos);

I have the NRF51 DK working with CrossWorks on OSX. I have the blinky example working.
Now I would like to figure out how to get very basic HELLO WORLD type demo to iOS...
I am implementing dual bank DFU on the PCA10001 board using the latest SDK (7.2.0) and S110(7.1.0). I am able to enter bootloader from my app as detailed here:

I'm just reading the documentation regarding the analog digital converter and wonder why there is one bit in the configuration register for every analog input. What will happen...
I'm using a relatively large GATT db that has rd_auth and wr_auth set to true for every characteristic. This prevents the stack from automatically replying with cached values...
I'm using the MAX9814 electret pre-amp's output as an input to an analog pin of the nRF51822. The MAX9814 has a 1.2V swing at 1.2V DC (so it goes from 0 to 2.4V). VDD for...
Hello,
I have some questions about the DC/DC conversion factor in nRF51822.
In the datasheet nRF51822_PS v3.1, Figure 11 shows the graph about conversion factor...
