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 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...
I want to send a set of 64 bytes data with ble. as I understand, the max data length I can send within a characteristic is 29 byes. when I send 4 bytes data it works fine...
Is it possible to bit bang a 9600 baud UART on the nRF51822 while the BLE softdevice is running?
The reciprocal of 9600 baud is around 100 µs, so the interrupt handler...
Hi Team,
My application is based on nrf51822 SoC in which I am using
BLE and UART interfaces.
There is single UART available and I have used it in communicating with...
Hello,
I am using am using sd_ble_evt_get and sd_app_evt_wait in an endless loop for handling all incoming events.
If I block this loop from executing, I'd expect that...
Hi all
I'm struggling with the easyDMA UART of nrf52. I've got a preview nrf52-DK here where I wanted to make a simple example with the following code but I never reach...
I'm doing a custom board with a nRF51822 FAAG0. I have in it the ST BAL-NRF01D3, with a 0.8pF capacitor.
In the forum I read in a post that some versions of the nRF51822...
Hi everyone,
I am using the nRF51 SDK 10.0.
The documentation for the Debug Logger API suggests sample code like:
uint32_t retval; // Initialize module
retval = app_trace_init...
I want to use the J-link to program the nRF51822 via SWDIO and SWDCLK, every time I click the
"nrf51 programming", the studio stops working immediately, PLZ help, thans
I'm trying to set up communication between an nrf51422, and an nrf24l01+.
The nrf51 is supposed to be the PTX device, and the nrf24 the PRX device.
Communication from PRX...
I was learning GPIOTE using the example provided in SDK 9.0.0. (examples\peripheral\gpiote). The example only uses GPIOTE task and a timer to drive the task through PPI. ...
We have created a firmware and encrypted it with a private key and made it public. When we download it to the chip it's decrypted with a public key stored in the chip. Right...
I have about 200-300 sensors, each requiring to send data at around 0.5-1Kbps to a central node (coordinator/master node), what will be the network configuration/topology...
