Hello,

I am using the MangOh Red with a WP7610 and trying to monitor the transmit power of the modem during LTE operation. I can not find a function in the [le\_mrc\_interface.h](https://docs.legato.io/19_11/le __mrc__ interface_8h.html#a09ff33b24fd01be18a145b2b3f1f579a) to perform this measurment. I’ve also tried some of the AT commands like !GSTATUS but that returns – in the TX column.  
Is there a MangOh red command that returns the Tx power?

You can do “ping [www.google.com](http://www.google.com)” in the background and then typing AT!gstatus? in AT command port. You will see the TX power sometimes will have value:
