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,
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...
Hello,
Does nRF905 communicate underground? I mean if I bury one chip underground would it be able to transmit to a receiver on the ground?
If yes, How deep could the...
I'm looking for a way to speed up connecting to a peripheral (IOS or Android device, nrf52 is central). I understood that caching data to avoid needing the discovery phase...
Scan in the background while connected to one Peripheral in a multi-linking central.
In this state, we confirmed that there was a period during which Central could not communicate...
Many of your descriptions of your product keep talking about Bluetooth 5 support.
For example: https://www.nordicsemi.com/Products/Low-power-short-range-wireless/Bluetooth...
We are using the secure BLE bootloader from the nrf52 SDK versio 15.2. We did put in our own key files, but other than that I think that I don't think we changed much in the...
Hi, I am a beginner with nRF52840. In the SDK under modules/nrfx/templates we find a file "nrfx_glue.h".
This file contains macros that should be implemented according to...
Platform：NRF51822, SDK12.1 S130
Phenomenon：By flipping the led light in the NRF_RADIO_CALLBACK_SIGNAL_TYPE_START event, it is known that the timeslot request is normal....
This maybe a stupid question but is there any reason to include support for older versions of the SDKs? I am using the pc-ble-driver approach and the example is full of if...
Is there any new information released about the GPS current consumption of nRF9160? I want to estimate the battery lifetime of a 1000mAh battery running the asset tracker...
Hi,
I am under long run test between coordinator and end device.
End device sends a message and goes into system off state until next event(door open) for minimal power...
Hi Everyone,
I am having problems writing to an array in NRF52832 without causing the program crashing at run time.
I declare the array to be 512 uint8_t long
then...
hi, I'm a fresher of this kind of development. My boss give me a board and let me run the Zephyr OS on it. But I am not sure whether I lack some things and how to assembly...
