why use 50ms and 400ms connection interval for testing the maximum data throughput(2M,247byte payload)?
Because 50ms can only send a pdu , and 400ms can send up to 8 pdu...
Hi,
I am using Keil IDE to develop nRF51822 project.
in main(), the command line

Hello,
I'm new to the Nordic SDK and I would like to ask you for help with implementation of PORT events for revision < 3 in "low power" mode instead of "high power" mode...
Hi Nordic,
I've built a ble app with a custom protocol, but am struggling with storing bonds, when running under freeRtos.
What I see:
central app crashes (hardfault...
Hello All,
I am new to this forum, I have been using nRF51822 for a while, and its a great little BLE chip. I am usinga BLE keyboard to send a key to iphone and I captured...
I WANT COMMUNICATION BETWEEN A NRF51422 AND NRF528321 BOARDS, IN WHICH IN NRF51422 BOARD I WILL MEASURE PWM COUNT(IT IS PHERIPHERAL) AND SEND IT TO NRF528321 BOARD WHICH IS...
Hi,
I've been working on a way to detect and prevent replay attacks when beacons are used for sensor data. This is mostly used for home automation sensors, where I have BLE...
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...
Hello,
I will try to use the macro ZB_ZCL_SET_MODIFY_ATTR_VALUE_CB to define a callback when an attribut is written in my device. But the callback I write is never called...
