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, We designed a board using NRF5340-CLAA-R by following the Altium Reference design. Although when we tried to place an order with JLCPCB or PCBWAY, then informed that they...
Hi, I am pretty certain I have used RTTViewer before on the nRF9160, albeit not frequently. I cannot remember if I only used it on custom nRF9160 boards or if I used it on...
hello,
on our bm833 dev board, I scope (using a PIO) the time it takes for the bt_nus_send function to send 146 BYTES. The PIO goes to 0 after the callback nus_sent_cb has...
Summary
We are developing a Central application on the nRF7002 DK (nRF5340 SoC) using NCS v2.7.0 . The goal is to establish and maintain 11 concurrent Bluetooth Low Energy...
We're working on a project that interfaces an nRF9151 with a BQ40Z50 from Texas Instruments (via I²C / TWI / SMBus), and we've noticed the communication is unreliable. The...
Hi,
We are currently working on power optimization and want the device to wake up from the System ON state ( PM_STATE_SUSPEND_TO_IDLE ) using the RTC0 timer. However, I...
Trying to prototype a pinout on the nRF54L15 dev kit. We want P1.02 to be a GPIO pin instead of NFC. We followed the instructions to recover the device which erases the UICR...
Hi,
I am facing the following issue when i am calling west build from gitlab runner.

Hi,
I am trying to come up with a different approach to SED reattachment using a backing off MLE session. Is there a way for the SED to keep on the polling even when in...
I'm working on an nRF9151 application that periodically sends small UDP packets (20-40 bytes) over both terrestrial LTE and satellite NTN networks. The device uses PSM between...
Hi,
We are doing some RF certification testing, EMC and also FCC, and wondered if you had advise on setting the modem on and transmitting, potentially if there is some...
