If we enable PUART for calibration device during production by using
BLE_PROFILE_PUART_CFG (Baudrate = 115200) and call the init function
bleapp_set_cfg(... ... puart_cfg ...)
If we try to disable it when run-time on device. Any related API to call for it??
This thread talks about toggling the PUART with GPIO, so it may be helpful: How can I reassign port pins to GPIO after they have been assigned to puart_tx and puart_rx?
However, I believe this is what you need: How to Disable PUART
