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...

I learned how to use FEM driver through this blog . I added the corresponding...
Hello,
Is it okay to supply the nRF21540 with a DC/DC or do I need to use an LDO? Are there any performance differences of the nRF21540 when choosing one over the other...
I'm finding that the signal strength of the radio is too low in my nRF52840 custom BLE project. I would like to increase the radio power from the default 0dB as our RSSI values...
I made a custom model under ncs1.6.0 to publish uart data. When the data I want to publish exceeds 85 bytes, an error occurs in debug:
<err> bt_conn: Unable to allocate...

I'm facing an issue where I cannot enable NFC and softdevice at the same...
Hello everybody. I am currently evaluating some BLE Tags, if they can be used as an BLE doorkey. The chips I am talking about are the following: nRF51802 nRF51822 nRF52832...
Hello support team,
I try to get the NRF52840 DK to work as a central with FreeRTOS. Connecting and getting notifications works well, but the device freezes on a disconnect...
I am running a Zephyr OS, and I am using the mbedtls APIs to do my cryptographic operations using the Cryptocell as my backend. My question is should I be using a mutex of...
Hello,
We have a physiological monitoring system in production where we used NRF52832 as a peripheral. Connecting this peripheral with Windows bluetooth, we realised that...
