i am using RN2483 module (57600 baud) and put it into sleep mode with command sys sleep 36000000 (sleep for 10 hours). After 3 minutes i want to wake the module up with sending a break with 0x55.
(here i put the Rx line to low for 300µs followed by transmitting 0x55). The module respond with ok and all seems good. Then i transmitt a few data to ttn - this also works fine.
But after transmitting, i put the module again in sleep mode but this doesnt work. It seems that the module hanged. Enclosed the image of waking up procedure.
