How do I receive multiple signals simultaneously at a single receiver (433MHz) with multiple transmitters ?
I am working on a polling system. This one is similar to the audience...
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...
Here are two simple functions to use when you want to use timestamps for time measurement.
uint32_t millis(void)
{
return(app_timer_cnt_get() / 32.768);
}
and for comperison of current with given…
There are times that we needed to flash the nRF5x series on a PC where the development software were not installed. The problem could be worst when network access is limited. With a HEX file on hand…

Setting up the Timeslot API
When you want to use the radio while still maintaining a BLE connection or have a task that you need to do uninterrupted by radio activity, you can set up a timeslot. The timeslot…
Radio Notification
In this tutorial we will set up a beacon example and modify it to use radio notification. Then we will use radio notification to light a LED when the radio is transmitting.
While this…
