Support for TTGO T-Beam v1.2 with SX1276 (915 MHz)

[wb2osz]

Kindly consider adding support for TTGO T-Beam v1.2 with SX1276 for 915 MHz. I was able to get it working with the following diffs. platformio.ini had sections for TTGO_T_Beam_V1_2 and TTGO_T_Beam_V1_2_SX1262. I added a similar section for TTGO_T_Beam_V1_2_SX1276. Your instructions did not mention changing the "[platformio] default_envs" line but I figured that one out.

Thank you for all the work you put into this. 73, John WB2OSZ

Sure John, I will have this ready this week as I was finishing some stuff over igate firmware before

[richonguzman]

please test now as versions for 915 has been added for all boards

[wb2osz]

Muchas gracias!

[richonguzman]

Muchas gracias!

please test and then write to know it worked for you ;)
