TSCH puts ONLY the radio to sleep, the rest of the functions are working well. So you can prepare your transmit buffer anytime, then when the node has something to send, it will be sent when the radio wakes up. The send function, doesn’t actually send immediately, it just puts the payload into a buffer, and the TSCH engine will transmit that buffer at the next available time slot.
There is no function that wakes up the radio, its in the stack.
