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 tried the following AT settings on the nRF9160 DK board:
AT+CPSMS=1,,,"00111000","00011110"
AT+CFUN=1
After this the modem enters PSM mode and the current is...
Hi,
