Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary?...
Hello,
I am using a nrf5340 dev kit. When I use SPIM the output from the pins gives the correct hex values but the output's amplitude is only around 100-200 mV. I know that...
Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
Hello,
I want to request AGNSS information from nrf cloud services using my nRF9151DK board. As a first step, I flashed the nRF Cloud multi-service application onto my DK...
Hello,
I just received my Thingy:91X which I purchased through DigiKey. I am trying to connect it to hello.nrfcloud but I keep getting the following message: " The fingerprint...
we are making a pedometer. when you are connected, you get notification for every step you make (just an integer)
you just did 50 steps. you can see it in the app. now...
I'm trying to implement a wake-up button on central multilink example. I.e, i need to implement the app_button in order to wake up from sd_evt_wat() function. The problem...
Please can any one tell me from where I can get this programmer? Nordic have stopped selling development boards in which we can get the programmer. I think this could be a...
Hi all!!
sorry to trouble you with this but I work over it for the last 3 days and no breakthrough..
I am using a nRF51DK with the MBED program. I am trying to download...
We are a contract manufacturer. We are trying to help one of our customer's with their bare board design which uses your NRF24L01+ (NRF24L01P) that comes in a 20-pin 4x4mm...
Hi!
We are currently writing a simple bootloader which reads the new application image from a external SPI based flash memory. We are using the S110 SoftDevice, which works...
Hi All,
I have been developing a bluetooth chip based on nRF51822 QFAC. I have followed the design rules very closely but at the end I do not get any bluetooth signal coming...
main.c Hi ,
I'm using nRF51822 and S110 stack and sd_6.0.0.
having an ble app UART example.
Facing a strange problem that when (from nrf Uart App)connecting and disconnecting...
Hi
I set one GPIO interrupt with low-to-high sense, but seems it did not triggle the interrupt when SD run.
I want to confirm the SD would make the interrupt loss? If so...
Hi folks,
I have a 2MHz clock (call it DRDY) coming into my nRF51 on one of the GPIO pins (call it AFE_DRDY). I need to read an external AFE chip on every falling edge...
I have a project where specification requires disconnecting immediately after sending a response to a BLE read request. I'm using authorized reads.
Currently, I'm using...
Hello,
I am measuring 5~6 mA of current consumption in standby mode, even when not broadcasting/connected. Why is it so high?
Aditional info:
I am using a custom...
I am using IAR workbench. Using softdevice s110 Version 7.
I have created a bootloader at memory address 0x3A000.
My application sits at 0x16000.
