Cipher suites
For TLS, the ublox SARA-R4 series AT Commands Manual provides the list of supported cipher suites
under the SSL/TLS security layer profile manager +USECPRF heading.
The only documented shared suites between the XBee3 Cellular LTE Cat 1 Smart Modem and the
XBee3 Cellular LTE-M Global Smart Modem are:
n TLS_RSA_WITH_AES_128_CBC_SHA
n TLS_RSA_WITH_AES_256_CBC_SHA
For the Telit LE866 cellular component:
n TLS_RSA_WITH_RC4_128_MD5
n TLS_RSA_WITH_RC4_128_SHA
n TLS_RSA_WITH_AES_128_CBC_SHA
n TLS_RSA_WITH_NULL_SHA
n TLS_RSA_WITH_AES_256_CBC_SHA
This list may be incomplete.
For the u-blox SARA-R410 and SARA-U201 cellular components:
n TLS_RSA_WITH_AES_128_CBC_SHA
n TLS_RSA_WITH_AES_128_CBC_SHA256
n TLS_RSA_WITH_AES_256_CBC_SHA
n TLS_RSA_WITH_AES_256_CBC_SHA256
n TLS_RSA_WITH_3DES_EDE_CBC_SHA
Server Name Indication (SNI)
We do not currently support SNI. Therefore servers which use SNI to present certificates based on
client provided host data may be unable to establish the expected connections.
