[0m[bt_socket_send_data] failed. Required key not available

It may be a problem with my source code. However, it may be a hardware problem or an operating system problem.

We bought a new Raspberry Pi. Please test with a new device. @Kasania @Kanu1755

D/BLUETOOTH_FRWK_API( 5542): bt-rfcomm-client.c: bluetooth_rfcomm_write(1337) > FD : 27 [31;1mE/red-light( 5542): [0m[bt_socket_send_data] failed.

I think this issue is related with method "bluetooth_rfcomm_write" in "BLUETOOTH_FRWK_API".

Kanu1755 commented 5 years ago

Hmmmm..... @Kasania found that messages so I think RFCCOM WRITE SOCKET ERROR @sjy5386 and might be not hardware problem I hope so...😂😂

sjy5386 commented 5 years ago

Thank you for testing. 😉 @Kanu1755 @Kasania It's likely a problem with my source code. 😥 Because the three Raspberry Pis are unlikely to be defective.

Kasania commented 5 years ago

Fixed issue. @sjy5386 @Kanu1755 This issue caused by data length mismatch. Desktop application is now read only 62 character. So should be send 62 character include of null character.

We don't need fixed data length anymore.
