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,
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.
When...
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...
Hello everyone, I combined work with a timer and an example from ble_app_aurt pca10040 s132, the problem is that the timer does not work evenly, yes, I know about the low...

I'm using led1 alisa for indication that network core is runing. But if I compile program, variable is not initiated from DTS. It looks like compiler does not init dtLed variable...
Dear Nordic,
we are developing FW based on nRF52832, SDK 17.0.2. We have 2 devices: BLE Central with SD S332 and BLE Peripheral with SD S112. The Peripheral is basically...
Hi, I am working on an IoT project that will use lwm2m, I developed an event manager architecture using the helloworld example base. Now that I am starting to develop the...
Hi,
Is it possible to check somehow if a BLE packet has been transferred (or not) from a peripheral to the central device?
Through a succesful transmission flag or something...
Hi, I'm using nrf52832 custom board and 14.2 SDK, S132.
In my program I'm using SAADC, PWM, I2C along with softdevice and PID. my device is working fine for some time but...
Hi! I've noticed that softdevice S113 is Bluetooth 5.1 compliant , and that the nrf52 family chips are Bluetooth 5.2 compatible in terms of hardware. a. Is there any target...
fds_init fails for several valid reasons, but my issue is how to recover. This for me was triggered by a firmware upgrade overwriting the fds file area. This can trigger fds_init...
Hi, I learned how to replace the softdevice for a normal application. I've replaced 140 with 340 in my app. However I don't know to do that for the boolloader.
What I want...
Hi Nordic,
I want to control an LED with the nrf GPIO, the LED Anode is connected to VDD, through a resistor, and the cathode is connected to the GPIO. Under this configuration...
I want to use the nPM1100 to battery manage, and supply power to the nRF52xxx - along with a heavy duty load ***directly across the battery***, so that full battery voltage...
Hi,
I'm running the experimental example: 'ble_nfc_pairing_reference_pca10400_s132' using sdk17.0.2 (and 17.1.0).
After I installed the micro-ecc following the guide on...
Hello
I am evaluating design of wireless communication in power supply with nRF24L01P , and I have 4 questions.
