case about nRF9160 serial_lte_modem wake up other MCUS by sending and receiving HEX data

[peter.min]

Hi,

ncs v1.9.1

dk: PCA10090 0.9.0

example :serial_lte_modem

Does this example have the following capabilities?

1. The hex data received from the server in EDRX mode is sent directly to the MCU

2. If MCU is in hibernation, the HEX data will not be received

3. Does Example A have this function, that is, when receiving hex data from the server, it sends MCU A wake-up signal, delays for A while, and then sends data to MCU

Thank you for all your assistance.
Kind regards,
Peter.Min

All communication is driven from the host controller when using serial LTE modem.

If you want to receive data on a specific socket, you should call the RECV:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/serial_lte_modem/doc/SOCKET_AT_commands.html#receive-data-xrecv

 

In certain protocol modes, you can enable notifications from the device, for instance in mqtt mode:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/serial_lte_modem/doc/MQTT_AT_commands.html#mqtt-event-xmqttevt

These will notify the host controller if a new event occurs, provided that the notification has been enabled.

 

Kind regards,

Håkon

Hi Håkon Alseth,

Hex mode can only be implemented by code.

Thank you for your information
