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.

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...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
Hello,
I've been playing around with with the nRFsniffer for a couple weeks now. Adafruit was out of stock of the BlueFruit LE Sniffer so I ordered a BLE400 and a few Core51822...
I would like to program the NRF52810 with the SoftDevice 132 and my bluetooth program. Is there any way to reprogram the NRF52810 over bluetooth rather than using a wired...
Hi,
I'm wonder is the speed of i2c on nrf52832 can be faster then 400kbps? even use EasyDMA, the speed still can't faster then 400kbps? I also look into the max speed of...
