RE: Thingy91: USB-UART bridge AND BLE gateway in nRF52840 ?

Hi,

[quote user=""][/quote]

Now let's say we want to implement a BLE gateway in the nRF52840 but still want to keep the serial programming capability of nRF9160.

Do you see any problem with that? We can simply merge the USB-UART bridge and BLE gateway sources?

As long as you take the UARTE1 for BLE-HCI (remove the CDC1 references, enable H4 on both ends), that should be do-able. However; we have not tried this, so there might be bumps in the road when implementing this. Be sure to have this fix when compiling the gateway:

Kind regards,
