My device contains a CC2541 BLE Module. I would like to use Production Test Mode for some radio testing. I understand there is a way to start this mode wirelessly, which would be ideal for me. As I understand it, I should be able to connect to the device through BTool and then send the HCIExt_EnablePTM command. But I'm not able to get that to work. I'm connecting through BTool fine but when I send the HCIExt_EnablePTM command I get a response indicating Unknown HCI Command:
What am I doing wrong?
One guess I have is that I saw the following in the TI BLE Vendor Specific HCI Guide, in the section on the HCIExt_EnablePTM command:
“This command is only available when the BLE Controller is built without external access to the Controller (i.e. when no transport interface such as RS232 is permitted).”
My CC2541 Firmware does have UART communication enabled. It requires a UART command to go into advertising mode - which is a precondition for a BTool connection. If that is the problem, is there some other CC2541 Firmware readily available that I could load on the BLE Module which allows entry into PTM?
Thanks,
Sasha
