I recently attempted to upload a new image via OTA. After emailing the zip file to my iPhone as an attachment and tapping on it, then tapping on the share icon several choices appeared but neither nRF tToolbox nor nRFconnect were there. I renamed the image emailed it again and they both showed up! unsucessful. mmdd.hhmm.zip successful mmddhhmm.zip
Is there a specific format for the filename that nRF toolbox/connect has specified that they will accept?
