10 months ago Ok, I got TTN join and Chirpstack join both working now with the #865 PR. TTN actually works without it, but Chirpstack will deny all joins/communication if wrong.
What does not work is as described by #858 - a re-join is not possible at all, if the connection is lost or we try to re-join from a fresh startup with .restoreOTAA(); I get a failed -1101 / DevNonce issues.
Following is the code part and log.
A second issue is the Antenna Switch which is on GPIO25, I finally figured out that it actually powers the antenna switch (no matter TX or RX) as described here: https://www.nico-maas.de/?p=2607 - Update to the Antenna Switch / GPIO25. Maybe you got a better idea on how to include this without having the global
pinMode(25, OUTPUT);
digitalWrite(25, HIGH); which does have the Antenna Switch powered at all times. To be precise: DIO2 controls the "direction" (e.g. TX or RX), GPIO25 just powers the switch. However, the switch should only get enabled if we actually want to RX or TX to keep the power profile as low as possible. Do you have any suggestions for that?

Hello there, I am trying to get the RAK11300 integrated module working using the "normal" Arduino Pico Framework ( https://github.com/earlephilhower/arduino-pico/ ) and the latest dev/master commit from this library.
The RAK11300 is a module directly wiring an RP2040 core to SX1262 module ( https://docs.rakwireless.com/Product-Categories/WisDuo/RAK11300-Module/Datasheet/#description ). The description is sadly very vague, but I got more information to work with (especially the link between the RP2040 core and the SX1262): https://forum.rakwireless.com/t/rak11300-pinout-rp2040-to-sx1262/8414
Most important infos are here:
With that, I used the default example as shown. Note that I had to re-configure the SPI1 interface, as its usually on different GPIOs on a stock RP2040. With this, the module intializes successfully, however, trying to OTAA on TTN either with a) 1.0.2, Reg Rev B (with AppKey set to false) b) 1.1.0, Reg Rev B (with AppKey) both does generate successful join-accept messages and forwards join-accept messages - however, the RAK11300 always ends up with a failed oota code -6
I am not sure yet if this is an error as shown in https://github.com/jgromes/RadioLib/issues/858 - or if its something about the RXEN that needs to be setup. I can hardwire the RXEN to HIGH or LOW - it does not change anything in the result (Update 2023-11-03: Actually I figured out RXEN is really controlling the power to the antenna switch. No matter if TX or RX (direction is controlled by DIO2 of the SX1262 directly) - if you want to do any transmission/receive you need to put GPIO25 as OUTPUT and pull it HIGH. More info and references to the source code here: https://www.nico-maas.de/?p=2607 - Update to the Antenna Switch / GPIO25)
As additional infos, here is the official repo which builds just for Arduino Mbed: https://github.com/RAKWireless/RAK-RP-Arduino/tree/main And there is also an AT firmware that can be built https://github.com/RAKWireless/RAK11300-AT-Command-Firmware/tree/main/RAK11300-AT-Arduino
The AT firmware works without issues on the RAK11300 and successfully joins.
Maybe you have an idea what I am doing wrong?
Thanks!
