Two ESP32 Bluetooth Comms with UART..Help

[kmmaran]

To all Experts.

I have two ESP32 boards and connected to two different computers each, what I like to do is use UART to send data using Bluetooth and received by Bluetooth and to UART on the other end.

I can see there is example using SPP Client/Server, and there is another SPP Accessor/Initiator. I have tried using Accessor/Initiator for initial starting point. But I don't see any data transfer in putty. Do I need to do anything additional to make it work?

For SPP Client/Server, I am getting below from Putty, for Server and Client. And no data transmission. Is there anything I have done wrong here with the setup?. Guide to troubleshoot will be helpful.

Server

I (645) GATTS_SPP_DEMO: EVT 22, gatts if 3
I (645) GATTS_SPP_DEMO: event = 16
I (645) GATTS_SPP_DEMO: The number handle =b
E (655) GATTS_SPP_DEMO: GAP_EVT, event 4
I (655) GATTS_SPP_DEMO: EVT 12, gatts if 3
I (665) GATTS_SPP_DEMO: event = c
