I am working on firmware for prototype of device which will use WP7700 module for cloud connectivity. Communication with MCU and WP module is going to be through UART and ORP protocol.
Since I do not have final hardware current plan is to use magoh red and communicate with it using UART on RPi connector.
I’ve configured UART1 for ORP as described in manuals.
And hooked up MCU to RPi connector (MCU TX-> RPI connector pin 10, MCU RX-> RPI connector pin 8, grounds are also connected). Even though mangoh is online on octave cloud, there is no response from it when my MCU communicates.
As mentioned in other threads, directly after reboot ORP device (that is Mangoh in my case, right ?) shall send SYNC packets until either a direct response is received from the remote OR the remote sends any other valid packet. But I see nothing on MCU RX pin (output from Mangoh).
I’ve also tried reconfiguring ORP to UART2, connect mangoh to my PC using other micro USB connector (CONSOLE) and connect to newly available COM port, but there is no activity (SYNC packets) as well.
Am I doing something wrong? Are there any exact steps that should be taken to troubleshoot the issue ?
