DeepSleepLock not released in LWIP/PPP with Cell Modem Mbed OS 5.6.6
Using a Cell modem on Nucleo 446 where I need to deepsleep 24 hrs between transmissions. DeepSleep is locked once I connect to LWIP/PPP and will not be released when disconnected or complete. Usually the UARTSerial interrupts have caused this but it is released at completion but a lock still remains that prevents DeepSleep. Any ideas.
