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 have to replace the bd address i can not be found in the ble_app_ibeacon_bcs source code.
Is it any way to fix the bd address...
Hi. I'm curious if there's a way to filter devices in the "Discovered Devices" list while scanning with MCP. We have a lot of BLE devices in our office, so the list is fairly...
Hello, I am looking for the way I can use PWM to control duty cycle of connection. I am really novice and my understanding about programming and Bluetooth protocol is really...
I'd like to use the pin sense function as the power switch of my NRF51822 device. That is to say, after the very first power cycle (reset or battery change), the device goes...
