Error after flash [Radio] Initializing ... failed, code -705

[Waldmensch1]

I checked out build and uploaded the sketch with platformIO. I only changed the Radio frequency to 868 in board_def.h. The rest is unchanged. Is the Radio chip selection wrong? How I find out which chip is on the board?

I had same problem, its because the RADIO_TYPE setting in board def, I have EU 868 too and had to change my radio to SX1276 - See below

/* Replace the model according to the actual situation

RADIO_TYPE option:

• SX1278
• SX1276
• SX1262 */

  define RADIO_TYPE SX1276

For me this fixed the issue
