to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
I would like to power the nRF54L15-PDK from an external source for power measurements. On the nRF52-DK I am able to power the chip through P21 and measure current through...

I have a task in front of me to design a battery charger.
In the program I use two interrupts to solve...
Hi,
We are working on power optimization for our project using the nRF5340 board. Our code implements an RTOS, BLE for data transfer, I2C and SPI for device communication...
Hello everyone, We are working on a low power design with a nrf52805. The low power feature did work well initially on the eval board. When the main supply drops away we power...
Hi,
When you use `bt_scan_filter_add` to add multiple UUID filters on advertisements, and pass `match_all = true` in `bt_scan_filter_enable`, the system will not behave...
