Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

Hi,
I am using a 52832 part as a peripheral communicating with a central running on an ESP32. It operates in the following manner:
1. When it is active, the peripheral...
I am getting a "Stopped by vector catch". This isn't particularly informative. How does one find the code location where the fault is generated?
Thanks
Hello everyone,
I just started learning BLE. I want to develop an application that gets RSSI from a beacon and displays the magnitude of RSSI using 4 built-in LEDs.
Beacon...
We want realize mesh network to mibile phone clients using BLE5
We assume we are have to use 3 types of devices:
