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.

Using nrf52840, is it possible to change advertisement from BLE5 long range to BLE4 on the fly?
i.e. interval of 2 sec, first BLE5 long range, than BLE4 and so on
I activated the iBasis SIM (Rochester, NY), but LED's 1 and 2 don't blink. LED5 is mostly on solid with a 1-second slight off-pulse.
AT commands from nRF Connect just timeout...
