OP_TXRXPEND pending #3

Hi all,

I'm using an EZSBC ESP32 Dev board with separate rfm95w (EU868) and having the same problem when using TTN V3 credeńtials. Problem starts when TTN sends an unconfirmed downlink LinkADReq after a regular unconfirmed uplink by the node (FCnt 19 in the attachment) and this gets answered with an LinkADRAns. After this, the node is starting it's deepsleep , and the value for LMIC.opmode that is written to RTC seems to refer to a busy mode. After waking up, the node continues with LMIC.opmode: OP_TXRXPEND OP_NEXTCHNL which causes the system to be unable to send data to TTN See Attachments.

@JackGruber : can we solve this issue by checking the LMIC.opmode status before writing it to RTC and -if necessary- correct it. Do we need the value for LMIC.opmode saved to RTC anyway?

Thanks a lot!
