Hi all, 

Regarding EVKIOTST87M01-2. In the design guide is mentioned the High Speed Interface (HST), in the same guide specifies that this interface requires an external Hardware TPA device, named Dongle HST Logger to recover the data flow for ST Analysis. 

The questions are:
Do you sale this Dongle HST Logger? Is the ST-Link compatible?
or is the the data available through the STSW-ST87M GUI?

Thanks in advance.

Dear Susana,

This HST is used only in case you face a serious telecom issue, which could not be solved remotely with our support. In this case, we would send you the TPA device so that you can record some data logs and send them to our telecom team (the logs can only be read with our internal tool).

The GUI will display the AT commands, the answers and the URC messages from the modem.

Best regards,
