You said "power off-on"
It's mean off-on only BT device and PSoC is still alive?
If so, it seems BT device need to re-initializing, simply.
Or another issue?
no I mean the complete system psoc board and BT module
I have written an error, I have CY8C55 Family and not CY8C58LP Family
It seems issue of start up sequence on electronically.
Warm start: the BT is stable in electronically when accept initiate command.
The other hand,
Cold start: when the BT accept initiate command, BT is not enough to rise up.
So, you would be better set CyDelay before submit the initial command to the BT module for a TEST.
What did you change since it was working correctly? (Even if it seems unrelated).
Can you describe a little bit more: what Bluetooth module? How is the communication process (what software on the PC side)?
now it works again, yesterday I deleted CyDelay before the initial command to the BT module. Thanks
