Hi,
On the nRF93M1 DK, we can switch between physical SIM and eSIM with %SIMCFG="SimSlot" (mfw 1.5.0).
1. Is SimSlot written to NVM on set, or in the flush at CFUN=0?...
We are implementing key handling for the nRF5340 and have come across an inconsistency between the CC312 and Oberon key management drivers. I wanted to verify if this inconsistency...
Hi, we would like to create a kind of game using 2.4Ghz emitters . The 2.4Ghz USB Dongle emits and the mobile phone detects the frequency + embed unique ID/code so we confirm...
We feed the nRF54LM20A’s VBUS pin (the USB high-speed PHY) from the nPM1300’s VBUSOUT, so that the PMIC’s input protection guards the module and the processor sees VBUS only...
With PM device runtime enabled ( CONFIG_PM_DEVICE_RUNTIME =y ), calling uart_irq_tx_disable (actual driver function uarte_nrfx_irq_tx_disable) may result in increase the PM...
So far, 10,000 chips have been produced. More than 100 chips encountered the situation where there was no pwm output at pin P0.20. The program is the same. A multimeter was...
