Safe temperature range for nRF52840 - nRF9160 UART 115200 without external crystals for HF clocks

Hi,

what is safe temperature range for nRF52840 - nRF9160 UART communication on 115200 baudrate without external crystals for HF clocks please ?

Thank you.

Hi

This config was temporarily disabled for current consumption reasons in a previous release, and has not yet been resolved. We are currently working on a fix to enable the XTAL while the current consumption stays at the desired level. We have not seen any issues with UART instability while this config has been disabled, but we can't guarantee stable communication I'm afraid.

Best regards,

Simon
