We are using smartbond tiny module (DA14531MOD-00F01002) in our application.
The thing is we have connected SWD pins from the module as shown in attachment, for debugging & development of software.
We had connected UART with flow control to our microcontroller as a host interface to module.
Since these pins are not accessible when assembled as a unit, How to proceed with Over The Air programming of the module (OTA) for first time ?
Also how to update the firmware for subsequent updates using OTA ?
Appreciate your help at the earliest !!
