I tried InSSID on my PC but can't find the Primo there.
The WiFi network where I originally configured the Primo is in my summer house (150km away ;-))
So I guess I will need to wait until we get back there..
A more general remark: I have a hard time getting the technical details for the Primo. With earlier Arduino models this was a lot easier, just download the data sheets from Atmel and you have most of it. Here there is little detail on how the NRF and the ESP play together. I also saw that the Primo has been retired, pretty fast for a relative new board with a high price.. So from that perspective the Primo seems to be a failure..
I am a big fan of ESP32 and use a few of them for several projects, but this time I wanted to update an existing project what uses a Leonardo and extend it with WiFi and BLE capabilities. Ideally I would use an ESP32 with Arduino Uno Form factor. There are a few about, but their suppliers do not give me a lot of faith, I would rather use a "known" supplier such as adafruit or sparkfun.
Having said all this, I still would like to "revive" my Primo
