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...
Is there another IC I need to integrate into my board to allow the chip to be programmed through USB? Also, is the same true for programming OTA? I understand that I will...
Is there anyway to enable the UART on a NRF51822 to be 7-bit data instead of the default 8-bit?
Lowest level driver structure I could find is
NRF_UART_Type (nrf51.h...
I'm using Master Control Panel for PC to try to test bonding with MITM security on the peripheral I'm developing, and I suspect there's something wrong with the Master Emulator...
I am using the nRF52 in 2Mbps proprietary mode. I am running my own custom stack to maximize data throughput. There are no re-transmissions in my design. I have a loop of...
In sample code for central devices,, the BLE event handler, on_ble_evt() , handles the `BLE_GAP_EVT_CONN_PARAM_UPDATE_REQUEST' by accepting the request. Is it possible to...
On pages 49-50 on the nRF51 Product Specification, in section 8.5.2, there's a bunch of current consumptions listed for the Radio with the DC/DC disabled.
Do those values...
Hi there,
I was hoping to first pull the SD version and application version from the device before I attempt to send an update.
Are these values exposed anywhere within...
LAST EDIT AT END OF POST
We are using a custom board with an nRF51822 programmed with a modified beacon application (which worked several months ago). After opening MCP...
Hi,
Everyone,
I am Using S130 and sdk 11.0.0.2-alpha with nRF51422 chip.
I have two crystal in my custom pcb,
one is 32 Khz crystal for LFCLK between XL1 and XL2 (pin...
My application is using the FIFO UART module to communicate with another MCU. It is also running softdevice S132 v2.0.0.
While most of the time everything runs smoothly...
Hi
Are there any major OSes/stacks (e.g. Linux, Android, iOS) that provide support for the L2CAP feature so that we can test our Nordic device against?
Thanks
Hi,
I would like to know what is wrong with my code, which is presened below. Each time the timer is triggered I would like that the program writes four bytes into the...
I have a project that requires a bluetooth central to be used to gather data from a HRM service, which shouldn't be too much of an issue. However, it also has to store this...
I have searched here for an answer to this, but cannot find exactly what I am looking for. I am trying to put my Rev3 51822 to sleep and wakeup via GPIO. When I enable GPIO...
