BC127 Melody 7.3 not getting out of data mode


I’m trying to get out of data mode, I wait for the guard time before and after I send the $$$$ and it does not get out of data mode, it’s this a bug?

Kind regards,

Hi @ssmavilete,

I have tried to connect 2 BC127s via BLE connection then enter Data mode, send data and exit Data mode with the command “$$$$” successfully.
The last “OK” in the left terminal is to send “$$$$” successfully and exit Data mode.


Hi @jerdung !
Thank you for the quick reply.

Can you show me your configurations? I truly don’t understand what I’m doing wrong.

Hi @ssmavilete,

I simply followed the steps of the Melody Audio User Guide, please refer to Table 2-7: BLE Connection Establishment on page 160 at the following link: https://source.sierrawireless.com/resources/airprime/hardware_specs_user_guides/bc127-melody-audio-7-user-guide/#sthash.85k1G6LL.dpbs

In addition, I attach the log used with the BC127:
Log BC127 device A.txt (1.2 KB)
Log BC127 device B.txt (423 Bytes)


Hey @jerdung ,

Thank you for your answer, I still don’t know what is happening because it seems that I’m doing the same as you.
One last question, do you know if the BC will go to sleep mode if there’s nothing being sent and received?

Kind regards.

Hi @ssmavilete,

Please refer to Deep Sleep Mode section on page 148 and DEEP_SLEEP configuration on page 98 of the following link: https://source.sierrawireless.com/resources/airprime/hardware_specs_user_guides/bc127-melody-audio-7-user-guide/#sthash.62v8khnE.dpbs

In addition, I have attached a log to configure sleep mode as below:
