| Sep 23, 2023 at 13:03 | comment | added | SamGibson♦ | Update: I now see that the "old" table 17 was labeled "RF Power-Consumption Specification" and the new table 4-4 (same table, same units within it!!) is labeled "Current Consumption Depending on RF Modes".|| Perhaps this situation does turn out to be a confusing description of a table in an old datasheet version, which they corrected in a later version. | |
| Sep 23, 2023 at 12:45 | comment | added | SamGibson♦ | @Dan - Hi, Thanks for adding the required link. However I don't understand what you mean when you say the new datasheet version "now expresses power consumptions for BLE in dB, so this post is no longer valid". Table 4-4 on page 47 of the current version looks to be exactly the same as the table 17 which you copied into the question (from an older datasheet version, I guess?). So the question seems to be just as valid now as before - it could just mention that the table in the question is (currently) now labeled 4-4 rather than 17. Yes? | |

| Sep 23, 2023 at 12:38 | comment | added | user222967 | @SamGibson I have tried to find the datasheet but it seems they have updated the version, see espressif.com/sites/default/files/documentation/…. This datasheet now expresses power consumptions for BLE in dB, so this post is no longer valid. | |

| Sep 23, 2023 at 12:30 | comment | added | SamGibson♦ | Dan - Hi, Please note the site rule which requires that when a post includes content (e.g. text, image, photo etc.) copied or adapted from elsewhere, that content must be correctly referenced. As a minimum, for online material, the source webpage or PDF etc. should be linked (see that rule regarding references for books / articles etc.). Therefore please can you edit your question to include the original source PDF link for that image (and please include references in future). Thanks. | |
| Sep 23, 2023 at 12:30 | comment | added | user222967 | I have edited the post to ask for watts instead, as I believe mAh doesn't make sense either, as you say. | |
