we have some challenges with our settings to avoid echo / feedback once the mic is connected to our pcb. Individually both (mic / speaker) work fine but we have been trying already 3 days without any improvement. in our previous module everything worked fine.
Does anybody have sample / best practice configurations for a smart watch?
Does anybody provide consultancy in that case - actually it should be a Sierra Topic but since we outsourced the production it is difficult to get the right person at Sierra.
Thankful for any help / advice,
