Hi Mark,

Hi Mark,

I dont know if you are going to be able to get the first character that your device sends, since the da needs time to wake up. You can send some dummy data at the beggining of the transaction untill the da is awake and then send actual data to the uart. You can notify the sender that the da is awake by toggling a gpio pin.

Thanks MT_dialog
