IC880a fails calibration, status 127. Service keeps restarting


#1

Hello,

I’ve got some problems with my setup. Last few weeks my concentrator was failing intermittent.
While debugging and checking different SPI-speeds (not the problem) and checking the connections (not the problem) I’ve found out that my board does not get trough it’s internal calibration (see below).

The voltage to the Pi and concentrator was a bit low @ 4.2 Volt, now it is at 5.0 Volt, but problem persists.

Does anyone know what to check next?

#2

Solved: I had both radio’s “tx_enable”:true in global_conf.json. The low voltage was probably the first error (now solved), while debugging I changed the config and introduced a second error.
