Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
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...
Hello,

Hi
we are using the nRF52840 and antenna signal i connected ceramic chip antenna(ACAG020-2450-T).
The above attached schematic of ant signal matching circuit schematic...
The only way I can see to do it is by two separate PPI calls. So Timer1 "tasker" is firing both the capture and clear... but will they execute sequentially?
Hi,
I just bought the NRF52850 DK. Currently I do not have the JLink connector to perform debugging using UART.
Is there is a way I can print printf or NRF LOG through...
Hello expert,
I would like to design a custom PCB that has two transceivers on it. One transceiver is working as a beacon/continuous wave generator (TX) and the other one...
On the basis of NRF24L01 +, an antenna was designed. after designing, I need to carry out the coordination of circuits. Do not tell me how best to do this, what values to...
I had a setup where I could DFU OTA a NRF52832 based board
I moved to a NRF52840 based board and now during the OTA DFU I get messages like this
I did try a new bootloader...
Hello, guys.
We have nRF9160DK and nRF Connect SDK v1.3.0. The version of the LTE modem firmware is the latest (v.1.2.0).
In our design, we are able to initially connect...
Hi Nordic team,
I just purchased a row of new nrf9160 SiPs for our IoT products. We are testing with new made cuicuits.
We use the same circuit schematic that worked with...
Hello,
Problem: BLE doesn't work on a OurBoard with nRF52840 (Schema1).
1) BLE example is working DevBoard (can see BLE server by scanner). On the OurBoard the examle...
Hello,
I've been testing HCI_UART from Zephyr RTOS on nRF52840DK and own device which has nRF52840 + FT232R as USB-UART converter. Regarding the own device it's a circuit...
