Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
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'd just start developping with the nRF52832 and I would like to communicate with a sensor using the I2C protocol. Has I am a stranger with the nordic uC, I would like...
Hi guys, me again.
I was very confused with my current process on developing with nrf chip now... so I would like to post my develop step and some problems I had so maybe...
I am using ATT MTU throughput example and I noticed that using CLI (calling cli_start) causes the main while(1) loop forever. In other words, wait_for_event does not block...
I just received the Nordic nRF52-DK, and am unable to do anything with it as my laptop does not recognize when it is connected. I do not have the original cable as I did not...
Hi!
I have AD5611 DAC connected to nRF51822 by SPI.
In DAC datasheet we need to send data by MSB first order.
Data packet is 16 bit length.
I feel variable uint16_t...
Hello,
I use the pca10040 and the problem is in 14.0 eaxmple ,when I push the button switch the protocol mode like : ble->gzll->ble and then I find the example loop into...
Hello,
based on the saadc example of SDK 11 I am trying to change the code to use the SAADC's local timer to sample the input given number of times (10 times for the below...
Hi,
well I struggle with another problem right now.
In case of some errors, I use 'sd_nvic_SystemReset' to reset the system.
But the WDT is used in the application. Thus...
Hey guys,
how can we use DSP math functions on the nRF52832 little monster?
Is there somewhere some documentation?
What about power consumption and performance?
...
Hi, I'm using blinky from the SDK12 as an example here with a nordic nrf51 DK (pca10028, onboard nrf51422) which I am using as a programmer with a custom board (with a nrf51822_XXAA...
Hi guys, just signed up here for some help.
I was learning how to develop a project with nrf51822 core chip. The one I'm using is this one . I also have a DK for the nrf51...
I'm attempting to change phy in a program based on the UART example and am following the same process used in the att_mtu_throughput for changing PHY.
Calling sd_ble_gap_phy_request...
Hi,
I'm using nrf52 + SDK11 + softdevice 132 2.0 and trying to integrate
the OTA dual bank bootloader. Using the nrfjprog tool I program the
softdevice + bootloader....
I am using the nrf52832 soc, and have a requirement to run the device in low power mode and using the timer with a timeout value in days? how can I do so?
Sample code would...
