Hi,
I wonder if it is possible to exchange data with P2P LoRa protocol between a Heltec HTCC-AB01 and Multitech mDot USB dongle using AT commands.
Multitech command reference manual gives an example of AT commands séquence for a P2P LoRa communication between 2 mDot modules :
AT+NJM=3
AT+NA=00112233
AT+NSK=00112233001122330011223300112233
AT+DSK=33221100332211003322110033221100
AT+TXDR=DR8 (US:DR8-DR13,EU:DR0-DR6)
AT+TXF=915500000 (US-ONLY:915.5-919.7)
AT&W
ATZ
AT+SD
My problem : I have no idea about the AT command sequence to send to the Cubecell module to communicate with a mDot module configured in P2P mode with the above AT command sequences.
I saw there is a AT+LORAWAN=0 command in Cubecell for a pure LoRa communication but all my tentatives have failed.
I am also a bit surprised by the multitech AT commands sequence because they specify a Network Session Key (AT+NSK) and a Data Session Key (AT+DSK).
Can anyone help me to achieve my goal or should i consider that it is not possible to make a P2P communication between 2 modules with different brands using only AT commands ?
