I was wondering how I can update my current code (see below) to reuse a single socket for multiple HTTPS requests, rather than opening and closing a socket for each HTTPS...
Does someone could tell me where can I find information on the sequencing of events BLE_EVT_TX_COMPLETE and packet transmissions during connection periods?
In my application...
Hi,
I am using nrf51822 evaluation kit, and the sample program i am working on is ble_app_hrs.
I have created 4 characteristics with notify property and also created...
Hi every one,
I'm working on a custom broad and I'm trying to setup a gazell based protocol.
I had a solution using soft device and BLE which worked fine but we want to...
Hello,
I'm a few novice in BLE, and I've got a problem.
I'm using a custom project based in UART example. I'm using Nexus 5 and nRF ToolsBox for text it. I'm saving...
Hi! I want to send the temperature data that I get from the beacon sensor not one by one but in packets for example of 100 samples. I have followed this tutorial devzone.nordicsemi...
Hello,
I am trying to get SPIS EasyDMA to work. Currently the SPIS MISO response with high when the CS is pulled low by another master device, but no correct data present...

How can I handle more...
Hi, is there RSA-512 cryptography (or maybe another asymmetric cryptography system) implementation for nrf51 or some implementation that can be easily ported to nrf51?
Hi. I played around with the MQTT example on nrf51822 module.
I get it connected to an openwrt device and can connect/publish to mosquitto on button press.
In next step...
Hello all
If you could please point me some directions on how to solve my issue, I would be grateful:

Dear Nordic Developer Zone,
I have a silly question. After searching in the Nordic and Bluetooth documentation, I didn't find what CCCD and SCCD mean. Theses metadata are...
I had a design on 4-layer PCB with nrf51822, then the requirement was changed, then the 2-layer is sufficient for routing.
But I thought 4-layer PCB is better for RF circuit...
I've run into a problem with an OS API call when running FreeRTOS on an NRF51 due to how ticks are corrected.
vTaskStepTick() is getting called while the MCU is awake and...
Hello all,
I am trying to activate ADC to measure a voltage every few seconds using nrf51822. When it is done, I supposedly deactivate ADC so it does not consumes while...
