ELS61-E: Hardware flow control CTS signal remains HIGH indefinitely | Thales IoT Developer Community

August 10, 2020 - 2:54pm, 1893 views

Hi,

I'm using ELS61-E module to stream binary data using ASC0, 921600 baud with Hardware flow control enabled.

I use the transparent TCP service as explained in the Cinterion® ELS61-E2 documentation (10.15.10, page 6/08/2).

The CTS signal remains "LOW" as long as I have stable LTE connection, but when the connection is 2G/3G the signal goes "HIGH" and remains in this state indefinitely, evenif I stop streaming data and reset RTS signal.

any suggestions what the problem could be ?

The module I have is:

Cinterion
ELS61-E
REVISION 01.000
A-REVISION 00.026.00

Best regards,
