Hi,

 

That at command shall still be present in SLM in ncs v1.9.0.

Could you elaborate on what the problem is in the newer version compared to ncs v1.8.0?

HI Alseth 

 In older version's Serial LTE modem (eg NCS 1.6.0), Command  #XTCPSEND support different data type. 

Detail could be showed as below 

Fig 1 NCS 1.6.0

However in NCS 1.9.0, command #XTCPSEND not supprot the various data type, all data has been convert to string.

Fig 2 NCS 1.9.0

The user's question is in NCS 1.6.0, They can directly send their data by use hexadecimal string. after they porting their project to NCS 1.9.0, they found that they could not send hexadecimal string.

They want to know how to send  hexadecimal string data in TCP.

Hi,

 

The SLM application enters datamode if no data is supplied, as described here:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/serial_lte_modem/doc/slm_data_mode.html?highlight=xtcpsend#entering-data-mode

This was changed in ncs v1.7.0, as described in the release notes:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.7.0/nrf/releases/release-notes-1.7.0.html#nrf9160

 

If you want to send plain text, just omit the "1," to your original XTCPSEND command.

 

Kind regards,

Håkon
