Hello,

I would like to use AT command with 3V3 LVTTL RX/TX Pins on MangOH Red.  
My main goal is to simulate usage of HL7802 with WP7702.  
Is it possible?  
Thx for your support

Best regards

Francois

François,

Please see [WP7700 AT command Interface over UART using MangOH Red](https://mangoh.discourse.group/t/wp7700-at-command-interface-over-uart-using-mangoh-red/1574/2)

But you’ll get the set of AT commands for the WP77, which is different from the AT command set for the HL. Cf. respective AT command guides on [https://source.sierrawireless.com](https://source.sierrawireless.com)
