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...
Hi,
I'm programming the nRF51822 and save some user data into the FLASH by using pstorage_update . It works fine if I set system off mode, and wake it up. I can read back...
Hi,
I have been using nRF51822 with my Android app using Android's Bluetooth Low-Energy APIs.
In order to get more details, I am currently working on integrating the Android...
I'm looking at interfacing a typical Wheatstone bridge sensor to the nRF51822 ADC. This particular sensor only requires a mA or two for excitation and the output fits within...
When use the "nRFBeacons" app to update the info on my beacon the following happens:
Go to update tab.
Select "Connect"
Press "SW2" on beacon and see the LED begin flashing...
Hi:
I come across a problem when I debug NRF51822. I don't know how to config its clock.My board XTAL is 16MHz, and I want config is to 32MHz，Is the method below OK?
NRF_CLOCK...
Hi,
My settings are:
NRF_DRV_SPI_FREQ_1M, NRF_DRV_SPI_MODE_2, NRF_DRV_SPI_BIT_ORDER_MSB_FIRST.
I'm trying to readback 0xD8. The proper value should be 0x71. Instead...
Hi,
I am trying to use the nrf52 in serialized mode, where I was successfully able to program the connectivity board (using SDK 11.0.0) However if I try to load any of the...
We are using a module which has nrf51822 on it. Before we have programmed it, we were able to see it when we scan for ble.
But after we program we could not able to detect...
I am building an automated test stand for programming our production devices. After programming, I need to pin-reset the device to leave debug mode so I can get an accurate...
We have an BLE application that we are targeting the nRF52 device for. The application demands using a UART interface to communicate to a host processor. In addition, we typically...
Hi all,
until now, I used nRF51 Chips on my board. I programed them trough the nRF51DK(PCA10028). But now I would like to work with nRF52832 Chip. I have a nRF52DK(PCA10040...
hi ..
i am new to mbed and nrf51.
softdevice is s130
if i enable the ADC in my project then other output(out3,4,5,6) is not working ok.
if ADC is not enabled then...
Thanks Stefan. The zip file making and updating steps work perfectly for me, if I follow your steps and make it from your stock pre-built "dfu_test_app_hrm_s132.hex". My question...
Hi
I have a problem when bootloading with nrf toolbox. It seems like when i flash files over 0x10000 in size the program overwrites itself. When i flash files with smaller...
I know this is somewhat "how long is a piece of string". I'm happy for guidance rather than solid numbers:
I'm trying to spec a "keep alive" circuit for an nRF51822 project...
In my S110 softdevice I want to accept connections only from centrals which passed OOB pairing.
My situation: There can be many centrals around my peripheral but only authorized...
We are trying to get an mBed-compiled hex file uploaded to production hardware but it is throwing the error "failed to read hex file".
The code is compiled for the nRF51...
Hello
I want to connect nRF51822 (on a readbearlab ble nano) to arduino micro which uses 5V logic on a 32U4 IC. I know I can use an external logic level shift, but I need...
