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...
Hi,
We're working on BLE communication between iOS and 51822 and found a data reliability issue. We have a custom characteristics that iOS read 60 bytes data from 51822...
Hi,
I have made some changes with how we update tick timer inside FreeRTOS and the results are promising
.
The improvement is
RTOS tick will auto correct if masked...
I went through a similar post for nrf51 which explains the numbers pretty well ( devzone.nordicsemi.com/.../) . I wanted to know what the values are for nrf52. The internal...
We have a nrf51822 device that has to send 6 bytes back to back at 12K8 and 6-18 bytes at 38K4 in the future.
The bytes are in an array and do not need to be generated...
Hi experts,
I have just tried lbs example. I saw in the ble_lbs_c.h, the base uuid and service uuid are defined for the peripheral peers who are going to be connected....
I'm developing with nRF52, SDK 12.2 and softdevice s132 3.0.0 . I modified the saadc_ble code from github which uses SDK 11.0. It seemed to work fine. But disconnection happens...
Hi,
I adapted the ble_app_multilink example to continuously scanning for ibeacons and collecting rssi data.
Data are then sent via UART to a microcontroller which provides...
Hi everyone,
Im new in embedded world so first sorry for maybe stupid or basic questions... Also there is not a lot of information about nRF52840 and IEEE802.15.4 :)
Im...
As a small team, we have to find silicons from retell market. Sometimes even the trader can not promise its source and batch. Here is a small list of nRF51822 available from...
I would like to hide BLE advertising from normal BLE scanner software.
And only be able to see such advertising with dedicated scanner.
I was thinking of changing access...
There have been a couple of questions asked that are similar to my question but in the interest of getting more clarity I am asking a new one as others have had accepted answers...
So, I open a nRF51 project today and found out that it failed to build. Turns out my uVision lost all of the target devices in its list, leaving only STM32 F0 and L0 series...
