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 have both the nRF8001 dev kit and the nRF51822 Eval Kit (EK). We are using the nRF8001 for most of our project with the BLE Arduino SDK. But I wanted to just load a...
Hi we are using NRF51822 board.
i flash ble_app_hrs application. then it is giving advertisement.
but when i call twi_master_init() function from main. advertisement...

Blicky project runs and I can set break points and run through them - watching the LEDs blink appropriately. However, the HRS and Proximity projects will successfully load...
Hi all,
I'm using the LE1 to do the mutilceiver,if I donn't use the dynamic payload,I can do it successfully.However,if I use the dynamic payload to do Multiceiver,the...
Hi,
For the LE1,I found that 32.768kHz crystal oscillator need long time(about 350ms) to running,I must do some delay(about 350ms) for the software then use the RTC,or...
In moving to the "rev-2 51422 silicon, we find that the app_timer inevitably fails after minutes to several hours. Power requirement moves from about .002ma to 4.5ma then...
Hi,
I am planning to use an external DCDC to supply the NRF51822 in Low Voltage Mode.
In the datasheet a voltage range of 1.75-1.95 on VDD and VDD1.8 is mentioned. ...
Dear all
I'm testing for RF stability. As i used 24LU1(host) with 51822(device) be the platform. For audio data transmission. 8k 8bits data rate.

Hi,
I don't have any problems running the bootloader with S110 7.0.0.-3.alpha on the PCA1001 but when using the same code (minus the led and button config of the PCA1001...
Hi,
I am having a hard time with the permanent storage.
I got it to work with updating a 24 bytes long struct in a persistant block of 32 bytes.
I noticed that the...
Hi,
What is the suggested method to change a pending request, and make it earlier than previously requested, without closing and reopening the session?
For example,...
Hello Gentlemen,
I'm looking for a good example on how to pair BLE sensor and Android using static passkey. I looked at ble_app_gls but I could not see how they set the...
I have the following code
