I ran in exactly the same problem. Tried several option (forward declaration, etc.) but did not manage to declare own function os_getBattLevel without modify the source code of the library....

yes, it supports downlinks and it works. Check your setup, i.e. cabling of DIO lines of SX127x chip. DIO0 and DIO1 *must* be wired to GPIO ports of the CPU...

It won't be possible to sync a node's RTC with DeviceTimeReq, if this shall happen with high precision. As far as i understand DeviceTimeReq in LoRaWAN 1.1 this command does...

When i was checking different power settings on my test node today, and comparing the LMiC code with SX1276 data sheet, i came to the same findings as stated in...

I opened [issue](https://github.com/mcci-catena/ibm-lmic/issues/15) in the IBM's repo on this.

If you're on a single core system, without RTos, you may use the lmic scheduler to execute your sensor read & send job, using lmic functions: ``` os_setCallback (osjob_t* job,...

Sounds like RX problem, possibly a timing issue. RX is needed with OTAA only. To debug this, active LMIC debug level and carefully analyse the timestamps during OTAA phase.

As far as i know you need to connect DIO1 with GPIO33 by an external wire.

That is the part in radio.c where RegVersion is checked. It seems your LoRa chip, probably a HPD13, reports different version than expected by LMIC. Put a Log line in...

Semtech chips sx1276/77/78/79 all answer with same RegVersion 0x12. 1278 is 433 Mhz version. Some TTGO boards do not have original Semtech chip, they use HPD13 modules (which probably use...
