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...
Hi. I've developed a PCB with nRF52832 and I'm having problems with the circuit. When I put my hands closelly of P0.00(XL1) and P0.01(XL2) the bahavior of nRF changes... I...
I apologize if this was already answered elsewhere - I didn't find it.
I have been digging in the nRF52840 source code for the serial_nRF52840 SES project to understand...
Hello, I am trying to switch from BLE_GAP_PHY_AUTO to BLE_GAP_PHY_CODED in runtime, and I need to change central event length via sd_ble_cfg_set(). Whether is it possible...
Hi, i am working on servo motor using nrf52840 development kit , i want to run parallely four servo motors , i have merged the ble_app_uart+pwm library example ,
1. As of...
Hi,
I am using an external RCT module to provide 32.768kHz square wave for the nRF52832 instead of an external crystal oscillator. When the system goes to deep sleep mode...
Hello,
I'm aiming for flashing the nrf52832 via SWD via my own SWD implementation.
I'm good so far with the init phase, reading IDCODE writing registers. Long stort short...
Hello,
I am using nRF52840, SDK_16.0.0, SoftDevice S140 V7.0.1 and Segger for flashing the image. I am using ‘ble_app_blinky’.
I modified ble_app_blinky with below...

Hi,
I am working on nRF52840 (dongle) using nRF Connect for desktop on windows 7.
I was able to write the "peripheral/blinky" example and was able to see the output...
I am willing to use the uart or uarte driver to be able to have to buffers for the Rx, I have a huge flow of data at high sped arriving to the UART, I have read for few days...
My goal is that disabling the interrupts other than soft device interrupt.
I think that this is achieved by d isabling interrupts below a certain level (in this case, 2...
Hello,
I am using NRF52840 with SDK 16. In my project I need to restart the chip after a successful pairing but I can't find any event that can make me sure about pairing...
Hi,
On zephyr, I am using the cryptocell as my backend to do the following operation:
