Do you have miniprog3. If yes can you try acquiring the device with that?
Unfortunately we don't have miniprog3. We use CY8CKIT-042-BLE and we don't have any problems with CYBLE-022001-00 module. We use SWD protocol.
Is there a difference between miniprog3 and CY8CKIT-042-BLE? Is there some reason why this could be a problem?
The kit uses kitprog and miniprog is a different hardware. Some options like powercycle mode is not available in kitprog.
1)Can you check the kit prog version?
2)Can you check ECO Capacitance Trim Values for EZ-BLE™ Modules - KBA218990 . Are you selecting the right trim value?
3)Are you facing issue on all boards or only some of the boards?
4)Are you powering the board by kitprog or an external supply?
Here are answers:
1) KitProg Version 2.20
2) Example that we tried didn't use BLE component(or ECO). So I assume that's not a problem.
3) We are facing an issue on all of the boards. We can detect module on only one board and program it, but on the others we can't detect the module. The one we are able to program seems like it's not running firmware and when in debug mode connection breaks sporadically.
4) We are powering board externally with stable 3.0 VDC.
