Hello Jelly,
thank you for your reply!
I followed step 1. and 2. and now I can download the firmware again.
But… the module stays in download mode, sending ASCII “C” and ignoring any AT commands.
When I press the reset button the output changes to “Q” for a short period, then it sends “C” again.
After
it stops sending “C” but still doesn’t respond to AT commands.
</s>AT+&<e>
How can I leave the download mode?
Are there other
commands? The official document only describes AT+…
</s>AT+&...<e>
commands without ampersand :idea:
Best regards
Andreas
