Re: ESP32 UART HCI RFCOMM

Update: I tried using the Android hack for connecting directly using a channel ID rather than a UUID (essentially skipping the SDP lookup), and this resulted in the same error - suggesting that the problem is with the actual connection rather than the SDP lookup. After trying a few more things I swi...

ESP32 UART HCI RFCOMM

I'm trying to use the ESP32 as a bluetooth coprocessor for a raspberry pi compute module using HCI. It seemed like everything was working, but then hit a last minute snag that I can't find a solution for. The device is able to successfully pair with the Android cell phone that I'm trying to use as t...

Re: UART HCI Mode with UART0

Found the issue. RTS/CTS were reversed and the host controller settings weren't quite right. All is working now, thanks for your help

Re: UART HCI Mode with UART0

Tried this, still having no luck. I'm not sure whether the issue is my ESP32 logic to change the pins or the setup on my host controller. In any case I was able to successfully flash the ESP32 over UART0, I used a modified version of the controller_hci_uart example. I used the following code to atte...

UART HCI Mode with UART0

Is it possible to use UART0 for UART HCI? I'm trying to use a ESP32-WROOM as a bluetooth coprocessor for a raspberry pi. On the PCB there is only one UART connection between the pi host and the ESP32, on UART0, similar to the example shown here: https://lb.raspberrypi.org/forums/viewtopic.php?t=1836...
