I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
Hello,
I could use some guidance on where to look for a power draw that I am not understanding. I am not a hardware engineer but have been tasked with completing firmware...
We experienced an issue in production, in which about 40% of boards had excess current consumption by about 75uA. Root cause was found to be the PIN_CNF of a GPIO pin. During...
Is there any way that a BLE event handler installed with NRF_SDH_BLE_OBSERVER, can stop the execution of other (following) observers?
I have various modules using their...
Hi
I am a student and this is my first project working on BLE. Please keep that in mind.
The end goal is to create a fingerprinting system with a Thingy (nRF6936) as...
I have modified the BLE app Blinky example so that the LED is enabled (state 1) on power up. However, this is not being reflected on the BLE side because when I connect with...
Hi, when debugging, I'm encountering this problem where relevant SPI registers (likely status registers) signaled a successful read before the actual data could be pulled...
We're developing a mobile application which will communicate with a satellite antenna over BLE. We will not have access to the antenna for a few months, and therefore we aquired...
I am using the UART to perform serial DFU on nRF52832. I got it to work fine using nRF Connect SDK 1.8.0.
Now, I need to pass some serial data to the APP when not in DFU...
Hi, I have to develop a new nRF5340/Zephyr/MCUBoot-based device that communicates with a Windows application via USB. The Windows application already manages other legacy...
Hello,
I'm trying to implement a set up of the ble device name from the NVMC UICR register.
But when I try to take it from the register and to set it has a name, it doesn...
Hi,
when using the spi peripheral in slave configuration, what can I expect at power consumption level? does the spi peripheral derive its clock from an internal system...
Hello,
I am using nRF52840 DK's P20 SWD to communicate with an external nRF52840 board . My setup works fine with nrfjprog running from command line. To communicate with...
Is there any example code using a QSPI image as the input for the bootloader instead of e.g. BLE? What format does that have to be in to begin with? Currently doing DFU updates...
Hello friends
I am fresher for Nordic semiconductor . I want to interface triaxial accelerometer of 15MHZ frequency with nrf52840 with inbuilt ADC and transmit the data...
