BC127-EXT: DEEP SLEEP

Hi,

Am working with BC127-EXT module. The area I have an issue with is DEEP SLEEP mode. I noticed when I connect via BlueCreation’s Android Melody App and characters less than 12 sent there is character corruption towards the end of the message. I have updated my module to the lastest firmware but the issue still persist.

This is my log…

BlueCreation Copyright 2017
Melody Audio V6.1.5
Build: 1496939390
Ready

SET BLE_CONFIG=0 ON 40 ON
SET DEEP_SLEEP=ON

The following sent via App.

abcdefghijklmnopqrstuvwxyz

The following is received from the module’s UART

RECV 14 20 abcdefghijklmnopqrst
RECV 14 6 uvwxyþ¯ø

I also noticed character corruption with the OPEN and CLOSE commands again whilset DEEP_SLEEP is enabled.

OPEN_OK 14 BL‰ÿ
CLOSE_OK 14 BLÿQÃ

Please can anyone shed light on my issue?

Hi,

I have seen this, can you confirm that if there is more than 12 character you do not see any additional character?I have a ticket to try to get it fixed at the moment.

Matt

Hi Matt,

I do not see character corruption for 12 and more characters.

Via the App I sent

0123456789ab

and received via module’s UART,

RECV 14 12 0123456789ab

but I do see character corruption for 11 and less characters.

Via the App I sent

0123456789a

and received via module’s UART,

RECV 14 11 0123456789ÿXÃ

Just repeated the 11/12 byte thing and you are right, I have fed this back in.

Matt

Hi Matt,

Have you had any update to your support ticket on this issue?

Thanks.

Hi,

Its not in the code we have access to so have had to raise a ticket with the chipset manufacturer, as a result it is beyond our control.

Matt
