I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
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...
Everything was fine until I updated to the latest SDK version 6.0.0 and the new nRFGo ap version 1.16.1. Now when I try and connect to my device I get J-LinkV4.52c Error ...
Hi all,
I am trying to send and receive generic data from the L2CAP layer. So, initially I am just trying to send data with sd_ble_l2cap_tx with S110. The code that I am...
We are considering moving from the nrf51822 wlcsp to the qfn48.
We would like to minimize the changes to our design. Can we, should we keep our wlcsp antenna design and...
Exactly what baluns are known to work with the nRF51822. I believe there is the STMicro balun and am uncertain about the status of the Johansen balun. Is there a list of preferred...
Hi,
We are using nRF51422 in our project and we observe a strange thing, that even there is no external pull up resistors, the I2C communication using the built-in TWI...
Hi,
I am trying to power off and/or disable a RR[0] with no success.
I am Powering OFF the watchdog in main and then successfully POWERing ON in wdt_init but then I...
Hi,
I am trying to create a star network with 12-16 slaves and one master.
The master would be a nrf51822 and the slaves nRF8001/2.
The slaves would not transmit...
Hi,
I'm using the UART_OVER_BTLE base example and I'm investigating what needs to be done to enable security.
Using the Following security configuration the device stops...
Can you tell me which antennaes i can connect with nRF 8001 to make it discoverable and transfer data. And i think pi network is solved depending on the antennae only. Can...
Hi,
Is it possible to extend the RAM memory by using internal flash memory?
Actually i need to collect 4KB of data from accelerometer and flash it to the EEPROM when there...
I'm working on a device which may spend months, or even years as deep as 1000 ft underwater...a harsh environment. Accordingly, the PCB will be completely encased in plastic...
Is it possible when using the S110 softdevice to limit the maximum number of packets per connection event? I would like to reduce the maximum amount of time the CPU spends...
