Hello,
I am using nRF52840, SDK_16.0.0, SoftDevice S140 V7.0.1 and Segger for flashing the image. I am using ‘ble_app_beacon’.
1) ‘ble_app_beacon’ will only broadcast...
Hello Devzone:
Would I be correct if I assume enabling APPROTECT should prevent writes into UICR? - for other readers, NO, IT CANNOT PROTECT AGAINST SOFTWARE READS/WRITES...
I am in the process of adding central functionality to ble_app_buttonless_dfu on a PCA10056.
When I call nrf_ble_scan_filter_set, the resulting builds debugging is broken...
Hi, I want to use the ADC peripheral (SKD16) and I am looking for the most energy-efficient way of doing this. I design a prototype that will be based on nRF52840 IC and will...
For a temperature sensing application, I am trying to implement a TWI interface with a TMP116 temperature sensor. I am using Keil uVision 5 to write the program. I have been...
I am attempting to port a BLE application to the nRF52840. The original application used a standard HCI serial interface so I am trying to adapt that to use the Nordic SoftDevice...
Calling the lte_lc_connect() function eventually leads to the code breaking on:
