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,
I am working on nRF51822 Microcontroller. I am not using any kind of stack I mean Bluetooth etc. I have a simple nRF51822 microcontroller and am running a simple application...
Like the title says, I'm making a call to nfc_t2t_emulation_start, and getting NRF_ERROR_INVALID_STATE (0x08) back.
The only prerequisite that I'm aware of in order to...
I'm testing with S132 nRF52 SoftDevice 3.0.0, BLE dfu operation with single, nRF toolbox on Android version 1.16.5.
I have checked the example in SDK, nRF5_SDK_12.1.0_0d23e2a...
Hi,
I am trying to make communication between two nrf51822 modules. I am using nrf11 SDK, In this i am using proprietary_rf-> esb_low_power_prx(ptx) examples.
In this...
URGENT
First of all, I have to mention that I dont understand PPI.
I have application which uses PWM to control a pump which is connected to the nRF52. To the nRF52...
What would be the payload size? That is, without any ble involvement? I assume it's 31 bytes? Or maybe this question is invalid since you can transfer unpackaged, raw data...
Issue: when the battery level is requested for the first time from mobile its responding correctly. but, when it is requested for the second time from mobile, disconnection...
We are trying to import blinky example(Keil project) to SES, we could succesfully build the eaxmple and dump into nRF52-DK, example is from SDK12.1. After we dump into kit...
Hi, I'm planning to create a custom PCB that uses nRF52832-QFAA.
Currently, I chose the Q22FA12800025 32MHz crystal to use, which is the same one in the PCA10040, I believe...
Hi,
I use nRF51822 with 256k flash and external sensor, and i want to write the data i receive from it via SPI to internal flash?
After the data received i want to send...
I've seen a few posts in regards to the usage of MCP in a windows virtual machine. From what I can gather, this setup just will not work, however I haven't really seen an...
Hello:
I was wondering about the random addresses programmed into the FICR on some of the devboards that I have. I read the devzone and it appears that the DEVICEADDR is...
I read that the DEVICEADDR is always in the advertising packet, so i need to take these data from the master each time that a slave is conected to them. I trying do something...
I'm using nRF52+SDK11.0.0+s132. In the ble_hrs PCA10040 example, the following are defined:
BLE_STACK_SUPPORT_REQD
BOARD_PCA10040
NRF52_PAN_12
NRF52_PAN_15
NRF52_PAN_20...
